All. Right welcome everybody, um I'm, Taylor Wilson for. Those of you who know I am I'm a nuclear. Physicist, in my day job I built. A nuclear reactor, and I was 14 I think that's one, of the many things that we share in common our interests, and things. Of that nature and we're really young so I'm excited to be here today to interview, dr. Kaku about. Physics. And the, future so, I, guess, what that we'll get, started I will, say that when we finish our, talking, up here we're, gonna take questions from the audience so if you want to start thinking about some. Questions. That you have for dr. Kaku about the future of humanity, or physics we're, happy to try to give you an answer so, with. That thank, you for joining us this morning my, pleasure yeah I wanted, to start with kind of something. That's been in the news the, last couple weeks and I'm sure a lot of people are really interested in and that's that picture. Of a black hole that, was taken by the event horizon telescope, maybe, you could talk a little bit about how you. Feel seeing that image and what that tells us about the. Physics, of the universe well. When, I was a grad student at Berkeley. Black. Holes were considered science, fiction it, was, considered, like finding. A unicorn, it's. A fabled, animal, everyone, talks about unicorns. But no one's ever seen one because they don't exist now. We've, got, it in the bank we've actually photographed, the silhouette, the shadow, of, a black hole but, that's just the beginning, you. See this black hole is spinning spinning. Rapidly, we've. Clocked black holes at about a million miles an hour and, if you look at Einstein's, equations. And. Have. A spinning, black hole they. Don't collapse, to a dot they. Collapsed, to a ring a, ring, of neutrons, such. That centrifugal, force prevents. It from collapsing. It's stable, if, you to fall through, the North Pole of the, Ring you. Wind up mathematically. On a parallel, universe, and. If you go a second, time, you, wind up on another parallel universe, and. You keep on going through, the ring it's, like going through an apartment, building hitting the elevator. Each floor, being. Another, universe. And. We want to know is that real, or is it just a mathematical, fiction. A unicorn. In other, words a wormhole. At the center of a, spinning, black. Hole and. That's, what we want to do with, the next generation. Radio. Telescope. Technology. Okay, that's fascinating, so this idea that black, holes. 4050. Years ago we're something that we might have had theoretical. Evidence of or even in direct observational. Evidence of but now we have that real first, true. Direct. Observational. Evidence of and so what you're saying is maybe, what's next, what. What could those other, possibilities. Be for, objects. That we have not yet seen right in other words a black hole is a cosmic, roach, motel uh-huh. Everything, checks in nothing. Checks out, but. Then the question is where does it go where. Does all that stuff go if it falls into a black hole some. Theorists. Have stated, that maybe is blowing out the other end as a white hole so. Maybe there's a white hole on the other side of, a black hole such. That it spews, out matter now. Doesn't, that sound, like the Big Bang, some. People even think that maybe our universe is. A white, hole and, that, we are connected. With a. Umbilical. Cord to another universe, faster this is the multiverse, idea which, is now gaining a tremendous, amount of theoretical. Credibility. Though, of course we have not yet proven this theory at all well. That's a good segue talking about multiverses, and, into. Something that you're quite familiar with string theory so maybe you want to tell everyone kind of your background and how you ended up in physics you're, from this area originally, correct that's. Right I'm a local kid I was born in San Jose I grew. Up in Palo Alto he, went, to school up. To High School in power. But, when I was 8 years old. When, I was 8 years old, something happened, which changed.

My Whole destiny. And that, is in, the newspapers, they. Announced, that a great scientist. Had just died and they, put a picture of his, desk on the front page and the, caption, said this. Is, the unfinished. Manuscript. From. The greatest scientists. Of our time and. I thought to myself why. Couldn't he finish it what's. So hard. That. A great, scientist. Could not finish this theory it's a homework problem right, why, didn't he ask his mother what. Could be so hard so. When did the library, I found that this man's name, was Albert. Einstein. And that. Book that book, on, the desk was the unfinished, theory. Of, everything. He. Wanted an equation one inch long, that, it would allow him to quote, read, the, mind of, God. So. I said to myself wow, that's. For, me yeah, that's what I want to work on I want to help finish this. Great, theory, that I understand could not finish well, today we, think we have it it's, called string theory has. Not yet been tested, but, we think that this could be the. Final unicorn. The, final, theory, of everything. So. That every, Neutron, every, proton, every, electron, there's, nothing but tiny vibrations, on, a tiny, string this, is an electron, that's. A quark this is a neutrino. Nothing. But musical, notes on a string, physics. Therefore. Is the, harmonies, you, can write on a string. Chemistry. Is the. Melodies. You can play on vibrating, strings the, universe, is a, symphony. Of strings and then, the, mind of God. The. Mind of God that Einstein, wrote about for the last thirty years of his life the. Mind of God is. Cosmic. Music. Resonating. Through 11 dimensional, hyperspace, amazing. That is the mind of God so. This this idea this grand, unified theory that's based on string theory is. Something. You've spent your entire career, working on that's. Right we want that equation, when inch-long now. Four strings not membranes, but just four strings we had that equation yes, that's my equation I'm the, co-founder of string field theory which, allows you to summarize this vast body, of knowledge into. An equation one inch long but, today we have membranes. M-theory, which makes things more complicated, so. It's unfinished, so. If one of you in the audience ever, figures, out the final, theory be, sure to tell me first. We'll. Split the Nobel Prize together. Now. It's not a bad deal for you. That's. Really, interesting so this is the idea of taking the, physics large. Like. The. Laws that govern, gravitation. And the like and. Unifying, it with the theories, that govern the very small and the very hot the the quantum rules of the universe so your idea is that the, best way to solve this problem is through, string theory, that's, right nature has a left hand and a right hand the. Left tennis you said is a theory of the very big black, holes the Big Bang Einstein's, theory, of gravity but. The other hand of God is. The, quantum theory the theories are very small so why should we have two hands, yes, but.

Don't Coordinate, with each other and that's what we do believe that there is a final theory yes and we're, gonna test it the, Lauren change on collider has. Given, us the Higgs boson giving, us the so-called god particle but. Now we're, gonna build a successor. To. The Large Hadron Collider the Japanese. With, the international. Linear collider the. Chinese, with, a circular, Collider and the, European. Union, three. Three. Ventures, have been proposed for, the successor, of the Large Hadron Collider but unfortunately. Not, from the United States we're. Left in the dust, one again yeah, but that's the way to really, test the theory is to build a very large Collider collide, the particles and, see, what comes out our, super, collider was cancelled in the 1990s. To be built outside Dallas, Texas, one. Reason why it was canceled is because. A congressman. Asked, the physicist on the last days of hearing quote, will. We, find, God with. Your machine if. So I will change my vote well. The. Physicists, didn't know what to say. Ten. Billion. Dollars, to, find God so. He said we're gonna find the Higgs boson. Well. All the jaws hit the floor in, the United States Congress ten, billion. Dollars, for. Another goddamn subatomic particle. They. Took the vote and it was cancelled yeah since, then we, physicists. Had to ask ourselves how. Would, we answer that question yes, the next time someone asks us will we find God with your machine, how, will we answer, it mm-hmm I would, have answered it differently. I. Would. Have said. God. But. Whatever signs, or symbols you ascribe to the deity this. Machine, the. Super collider will. Take us as close as humanly. Possible to, his greatest, creation. Genesis. This. Is a Genesis. Machine, it. Will recreate, on, a small scale the, most incredible. Event in the history of the universe, its. Birth. Unfortunately. We said Higgs, boson. Not. As exciting, wrong, answer, wrong. Answer and you, have a little. Personal. Experience of colliders, maybe you want to talk a little bit about what you built when you were in high school yeah, well just like you when. I was a junior. In Cubberley, high school which is just about two miles from here I decided. To build a particle accelerator an, atom, smasher in my mom's garage. So. I went to my mom and I said mom can, I have permission to build a two point three mil, in electron-volt, betadron electron, accelerator, in the garage and she. Kind of looked at me and said. Sure. Yeah. Why. Not no and don't forget to take out the garbage, yeah, so. I went to Westinghouse. I got 400, pounds of transformer steel I went, to Varian got 22, miles of copper wire and on the football field over, Christmas, we're, on, 22. Mile of copper wire it, finally, was finished it soot consumes, six kilowatts, of power, I put. Plug it in I close, my, ears and. I heard this crackling, sound is all this energy surge, in the capacitor, bank and then, I heard this pop pop pop sound as I blew out all the fuses, in my mom's house yeah so.

The Whole house would be plunged in darkness and, my poor mom she must have said to herself. Why. Couldn't, I have a son who. Plays basketball huh. Maybe. If I buy him a football and, for, God's sake why can't he find a nice Japanese, girlfriend. Why. Does he build these machines, in, the garage I, think, our parents would get along I think they have similar, similar. Opinions, about these things so, that's that's really exciting so that was kind of something. You did in high school and then you went on to college to, study, theoretical. Physics and develop, string theory and now I guess you spend, a lot of time thinking about the future and what. All this science of technology, means for our species and, our evolution, that. Leads me into kind of a segue, away from, basic. Theoretical, physics which is the, topic of the brain it's, something I think a lot of people are interested in knowing, what is the nature of consciousness, and and, this, thing inside our head that controls, our lives but, it's something we know very little about today, I. Know you've spent a lot of time thinking and writing about the. Brain and human consciousness. I was. Recently in China with. The. What. China calls the father, of quantum pangaean. Way and he, was talking about this idea of quantum. Consciousness or. The quantum mechanics, that underlie, consciousness. So I. Give. You that question for. Your thoughts what. Are kind of the quantum, mechanical, possibilities. That underlie, the, functioning, of the brain and, consciousness. Well. The two greatest, mysteries. In all of science, in all of science, the, two greatest, mysteries, are if one what. Happened, before creation, why. Did, we have a big bang what, banged, are there other universes. A multiverse, before. The Big Bang that's, out of space then. The second, mystery is inner space yes, what, goes on behind, your, eyeballs, we. Have a hundred, billion neurons in. Your brain, as, many. As stars, in, the Milky Way galaxy, each, neuron is, connected to 10,000. Other neurons and. So what is the brain we. Made a mistake fifty years ago and we're still paying the price for it today, fifty. Years ago we, made a huge mistake we. Thought the, brain. Was. A computer, a digital. Computer, but. You see the brain has no operating, system it. Has no programming, it, has no windows, it has, no GPU. It, has no Pentium, chip it, has no subroutines. The. Brain doesn't, have anything. Resembling. The. Brain except. Neural, activity. Fifty. Years later, after. This wild-goose chase, we. Now understand. That the brain is a. Pattern. Seeking. Neural, network, a learning. Machine and it, learns and rewires, every. Time you learn something new for. Example, your laptop, today is. Just, as stupid, as it was yesterday, your. Laptop, never, learns, anything. Except. Now we have deep learning, but. Our brain constantly. Rewires. Itself and, that process can, be recreated, with, MRI. Machines, with. Physics, we can look at the blood flow in, brain now and, actually, sees thoughts, as they move in the brain amazing. We, can actually test, Freudian. Theory we. Can actually test, old wives tales. For example, there's. An old wives tale that everyone, believes but no one could prove until now, that. When a man talks to a pretty girl he starts to act stupid. Yeah. Now everyone, believes it no but. We now know why. When. A man talks to a pretty girl blood, drains. From the prefrontal cortex and they, start to act mentally, retarded. Absolutely. True we can quantify this effect, now yes we can actually measure this dropping. Of blood in the, prefrontal cortex, because. Of MRI machines, we. Can now extract images. Images. Can be extracted, from the living brain with an MRI machine, meaning. That art design. Will. Be revolutionized. Artists. Of the future, will simply think. Think. Of a conception, and will, print it out on a 3d, printer hmm. Designers. Of Buildings, architects. Will, dream of their creation, and a. 3d, printer will then print. It out and, when. You go to sleep, the. MRI machine keeps, on plugging away and, will, print out your. Dream in, the. Future when. You wake up in the morning you, may push a button and see, the videotape, of the dream you, had the previous night, just. Don't tell your wife or husband. So. These are things that were considered, science, fiction, but, now we. Can put these on the Internet the. Future, of the Internet is. Brain. Net. Instead. Of sending digital.

Signals, Will. Send emotions. Memories. Feelings, on, the Internet, the first memories, were recorded, about three years ago at Wake, Forest University also. In Los Angeles. Memories. From animals can now be recorded, next. Will be, memories in monkeys, we're doing that today. Next. Is Alzheimers. Patients and, Alzheimer's, patients, will push a button and memories. Memories. Will, come flooding into their, mind and after. That, who. Knows maybe. We'll be able to upload calculus, or. Learn. Learning. Disciplines. Inside. Our mind and. By the way let me ask you guys a question. Let me ask you guys a question one. Day we may be able, to upload, reality. Itself just. Like in the movie The Matrix right. How, many of you early. Late, late at night just before you go to sleep how. Many of you have ever had that weird, feeling. That, strange. Feeling, that maybe. Life. Is, an, illusion. Maybe. Everything. Has been uploaded into your mind maybe, you're the only real thing, and, life. Is an illusion raise your hand raise, your hand if you ever had that feeling oh my. God you're all crazy. We. Have so many crazy people in this audience how. Can you be the only person in the world when, I'm the, only person, in the world. I'm. Just dreaming I'm, here at Google, I'm just dreamy I'm I'm in New York right now you know that yeah, I'm just about to go to sleep in New York I mean come on give me a break. But. This is this idea of kind of humanity. And our brains interfacing. With machines, and and that being kind of a future, step in our evolution as a species I think that's a very interesting topic to think about what, are the implications of, that both, positive, talking about being able to learn things at a fast, rate or download, memories. But you know potentially, the the negative consequences. Of that, we. Can definitely see with digital architecture, today the the problems that we face so imagine, if we're a part of that architecture well there's good news and bad news the. Good news is, that, information, will be everywhere. No we're almost, for free the. Internet might be in your contact, lens you'll. Simply blink, blink. And then. The internet, will appear inside, your contact, lens and who, were the first people to buy Internet. Contact, lenses. College. Students, taking final, examinations. College. Students will blink and see, all the answers, to my exam, right, there in their contact. Lens this, could be really helpful your, contact, lens will recognize, people's, faces and tell, you what. Their background, is and translate, Chinese into. German, into, English so let's. Say you're at a cocktail party and, there's, some very important. People at that cocktail party but, you don't know, who they are in, the, future you. Will know exactly who, to suck up to at, any, cocktail, party. On. A, blind date know, if your blind date says that he's rich he's, single, he's, loaded. But, your contact lens says that no he's three times of course pays, child support, payments. It, is a loser. It. Could be very useful now. That's the good news, yeah the bad news though the future does have bad news the. Bad news is that in the future. We. Will have lawyers. Significance, because only a human, can, argue, to a jury only. A human, can argue, to a judge robots, can't do that robots. Cannot, understand. Death ixora, morals, so yeah, people, involved, in person-to-person. Relationships. Like lawyers professors. Mentors, they. Will have jobs in the future yeah, but. The, more monotonous tasks, will probably be going away what. The more monotonous tasks they'll probably be going away well, those dirty. Dangerous yes the 3ds, dull. Jobs dirty, dangerous. Repetitive. Jobs jobs, that involve danger, those, jobs will be done by robots in, the future yeah that's. Interesting so okay we've talked a little bit about the brain we've talked a little bit about. Artificial, intelligence. When, to ask your thoughts on something I think it that is near to dear to both of our hearts which is space exploration and, we're, we're going beyond. Earth you've, written a lot about this subject about, missions. To Mars and and the planets and beyond what. Are some of the most exciting, things you can imagine us. Seeing in our lifetimes, and then maybe even.

Beyond, That well. The fundamental problem. With space travel, has been a four-letter word cost. C. OST. It, costs, $10,000. To put a pound of anything in, orbit, around the Earth that's your weight in gold your. Weight in gold that's how expensive, space, travel, is until. Recently. Prices. Are dropping, like, a rock now, for, example how. Many people here in this room have seen the movie the, Martian with, Matt Damon raise, your hand, Wow, that, movie, cost, a hundred, million. Dollars. But. The Indians, sent, a probe to Mars for, 70, million, dollars. So. Going to Mars, costs. A Hollywood, movie about going, to Mars cost. More, than. Actually, going to Mars. That's. How much space travel, has dropped, and, when. You drive a car and you commute to work do. You jump your car after, one ride no. Cars, would be expensive, if you junked, it after one ride but, that's what we do for rockets yes week's junk rockets, after just one, use we, junked them all, that's changing, with reusable, rockets, with, Silicon, Valley billionaires. Now fulfilling, their dream of creating. Fantastic. Devices, in space we're, entering the second, golden. Era of space, exploration I wouldn't. Be surprised, if some of your grandkids. Honeymoon. On the, moon I, think. The, moon is only three days away yes, or trip as costs, go down yeah, I think our grandkids, may honeymoon, on the moon it's great weekend location, not. Great scenery but well, look you like craters and dust. That's, great and we were talking backstage you're. One of the, one. Of the interesting. Things that come out of a grand unified theory and string theory is the explanation. Of, what happens, at, these very extreme conditions where, you have incredible. Amounts of energy incredible. Amounts of heat in, a limited space and and, we, were talking about could, this be a way to travel. Vast. Distances that. We can't travel today maybe. You could speak a little bit to that, well. Many people want, to know like in Star Trek can. You break, the light barrier can. You go faster than the speed of light well. It was Einstein himself, in. 1935. That, opened. The door to. Faster, than light travel when. He introduced, the, wormhole, that. Was the first paper, written. About wormholes, the first book about wormholes was, written in the 1800s. By. Charles, Dodgson Mossberg. Mathematician. Who, wrote a children's book Alice, in Wonderland. Now. This Oxford mathematician. Could not write under his name Charles, Dodgson yes it was a children's book so. He wrote under a pen name Lewis, Carroll. But. The looking-glass is, the. Wormhole you, put your hand through the looking-glass and, you, wind up on a different, space, and time, so. We think that yes that would be a way to go faster than, the speed of light now. What's the catch there's. Always a catch someplace first. Of all the, energy, necessary. To, punch a hole in space in time is that. Of a black hole you're. Talking about fantastic. Amounts of energy, second. You have to stabilize it, that means negative, energy. Positive. Energy to open the gateway and then, negative energy, to prevent it from collapsing. In other words stability. And this, has not yet been, worked, out it. Would take a very advanced. Civilization. To, do this now. I'm, on radio. And. I, broadcast, every week and, some people call me on the telephone and, they say professor. You're wrong. You're. Totally wrong the aliens, aren't very not a space, with warp drive the, aliens, are here, on. The earth and then. I asked them how do you know and they. Say well they've been kidnapped, kidnapped. By flying saucers they know that they're out there well. I have a word of advice the. Next time you. Are kidnapped. By a flying saucer, for. God's sake, steal something. There's. No law against. Stealing from, an extraterrestrial, civilization. Stir, yeah, no law whatsoever, an, alien, ship an alien, hammer an alien paperclip. Anything. So, that you have bragging, rights about, going into outer space. It's. Good advice it's good advice all. Right I guess we. Can start opening it up to questions if you want to make your way to the mics start to line up we'll, try. To do our best to answer the, questions that you have so over. Here you were the first doctor. Thank. You so much for coming out I'm really inspired I wanted, to hear some of your thoughts on. Ethical. Development and, how, we might be able to help machines, uphold, ethics, in our society. Ethics. And how we help machines, uphold, the ethics that we as a society hold, is that correct.

Well. Several, things first. Of all we have to make sure that. This. Technology. Is used by. The largest. Numbers, of people but. You see when technology, first, becomes, available it's, always for the rich when. The telephone, first. Came out over a hundred years ago who, had personal, telephones. It, was rich people, but, eventually we have things like Moore's, Law computer. Power doubling, every 18 months, and so with time the, cost of telephone, goes down we. Once thought that was going to be a digital divide, when. Rich, people would, have laptops, poor. People, would have nothing. But. Now we know that most children, are the first to be wired up because. If a child is not on the Internet, they don't exist, on the Internet. But, there's also another, ethical, problem, for the next coming decades. Some. People wonder when, robots, become. Smarter, and smarter are they. Gonna have a civil rights movement. Maybe. Because. In the future robots, may, be programmed, to feel pain. Today. We feel pain because. It's good for us otherwise. We lose our fingers. They our, fingers get burned cut, up pain, is, good, because. It prevents, us from destroying. Ourselves. Eventually. Robots, may have to feel pain, otherwise. We will tell them to jump off a cliff and they'll destroy themselves they, have to feel pain at. That point it has to be regulated so. We may have a robots civil, rights movement, to limit, the, amount of pain that a master, can impose upon, their, robot. Now. That of course is many many decades away but, eventually robots. May also be part of our ethical, understanding. Of Technology. When, they, feel, pain. Interesting. All. Right over here, dr.. Kaku one, of my earliest. Memories, is of watching, the Discovery Channel, and seeing you on there thank, you for the role that you played in shaping that part of my early childhood executives. And related. To that I wanted, to hear what you are excited, about when, it comes to expanding, the scale, and accessibility, of science communication into, the future.

Well. It used to be that mass media would. Stay, away from science because, quote science, doesn't sell, so. Back, in those days we only had three networks, and. Science. Was invisible, for the most part and most. People when they learned about science, they learned about science in school, but. There's a problem there first. Of all we're all born, scientists. When we're born we, want to know why the Sun shines we, want to know where we came from but. Then we. Hit the. Killer. Of. Scientists. Known to science, the. Greatest, destroyer, of scientists. Known to science, is. Junior. High school. While. We hit you in your high school it's, all over we, lose, scientists. By them hundreds. Of thousands. Why because. Scientists, made boring, It's, Made repetitive. You, have to learn to name, name, things, rather. Than learning the great principles, the, great concepts. Of science and that's, why more recently, we have the internet we have cable which. Brings, science, to an audience now. It, turns out that about a million people, subscribe. To. Scientific. American that's. The hard core these. People, will seek out science. Even, when there's no science, about a million people the hard-core but, then there's another five, to ten million people who. Will tune in, sometimes. To Discovery. Science Channel, National, Geographic if there's, something really, interesting happening. So, we know that we can reach five. To ten million people on a good, program. And then, with, the discovery, of the black hole we, can reach a hundred million people when. We, reach, residents. We resonate, with the people of the world so, we need more people. To, write books more, people to be on television to, do radio shows we, need more, people like that rather, than less people to become role, models for. A. New, scientific. Revolution. Definitely. Trade. Advice. All, right up here I think. Sir thanks, for coming out today, I was wondering your thoughts on NASA's recently. Announced. Plan to return to the moon in 2024, do. You think it's feasible. First. Of all I think we're gonna have a traffic jam. Around. The moon very, soon, first. The, NASA has. The SLS. Booster, rocket next, year, we'll orbit, around the. Moon then. We have Elon Musk of SpaceX. Who's, selling tickets. Tickets. To the general public, he's. Been sold out a Japanese, billionaire, bought out the entire tickets. For. The, Falcon, Heavy rocket, that is also fully, capable of, going around the moon and then. We have Jeff Bezos of, Amazon. Formally. The richest man in the world he. Has, a whole spaceport. The. Blue Origins rocket, program, to, go to the moon with, the new Armstrong, rocket. And then, we have the Chinese, the. Chinese have announced, they're gonna plant the Chinese, flag on the. Moon so. I think we're gonna have a traffic jam with. Three American, rockets one. Chinese, and perhaps one European, rocket, fully, committed, to go back, to the moon and the, question is why. Because. Costs, have been dropping. Technology. Is catching up you, realize it your cell phone your. Cell phone has more computer, power than. All of, NASA in. 1969. When. We put two men on the, moon that's, right your cell phone today has, more computer, power than all of NASA in.

Fact I think it's criminal what they were doing in 1969. Criminals. Say they humans, into space backed. Up by one cell phone would. You go into outer space knowing. That your rocket, is backed up by one cell phone that's. What we did in 1969. I think it's criminal, so. I think that we're gonna witness a second, golden. Era of space, exploration as, costs, begin, to drop not. 10,000, dollars a pound ninety. To one thousand dollars a pound but eventually a few hundred, dollars per, pound that's the goal oh. That's. Great. All. Right over here. It's. An honor to be here with you dr. Kaku, I have, a question simple one do. You believe humans, will reach a type one civilization. Okay. I I'm. A physicist, we rank, civilizations. By two things. Energy. And information, that's. How we rank, anything. Energy. Information. Energy. Of a planet, eventually. Reaches, type 1 so. That earth becomes, planetary. We. For. Example can, control, the weather, we, can mind the oceans type. 2 is stellar, where. You then begin to consume the power of a star, like. Star. Trek Star. Trek would be a type two civilization, where. They've colonized, a few solar systems, but not much more type, 3 is. Galactic. A galactic. Civilization like, star wars where. You can roam the Galactic space, lane now, what are we are. We type one that can mind the oceans play with the weather, well we type two that played with stars we. Type three that play with black holes. No. We're. Type zero. We. Don't even rate on the scale we. Get our energy from dead plants oil, and, coal so. We have all the savagery, of a type 0 civilization. Sectarianism. Religious. Hatred, racism, all, the garbage from the past but, by. The year 2100. In, a. Hundred, years time we. Will become. Type, one and, that. Gives, us room for hope, that. We will be a planetary, civilization, by 2100. For example, what language, will they speak, already. The, two languages, on the Internet are English. And Mandarin. Chinese. Look. At. The Internet what is the Internet, the Internet is the first type one technology. To. Arrive in, this century that's. What the internet is the first type. One technology, to, arrive that. We have the European Union type one economy, we. Have the. Beginning of a type one sports. Olympics. Soccer, we. Have the beginning of a type one music rock. And roll rap, music yuck. We have the beginning of a type one culture, but it's not guaranteed, that. We will make the transition, to type one because, we still have all the savagery, all the backwardness, of our, ancient. Past by. The way I once, spoke in London at the planetarium. And that little boy comes up to me a little, boy says professor. You're. Wrong. You're. Wrong there's, Type four and, so.

I Told them look kid. Look. Kid there are planets stars. And galaxies. That's it folks, planets. Stars, and galaxies. Therefore. We have type 1 type, 2 type 3 and, he said professor, you're wrong this type 4 I said. What energy, is beyond galactic, and he. Said the. Continuum. Now. Who here is a Trekkie who, understands, what I just said what, is the only type 4 civilization. On network television. The. Cue if, you. Did not understand. What just transpired, get. With the program. The. Cue is extra, galactic, and what is that energy dark. Energy, dark. Energy, is beyond, galactic, that, is the energy of a type 4 hmm. Interesting, all right we'll take one more question over here ok. First. Off thank, you for being here. Second. Thank, you for being somebody else who had a question about the Kardashev, scale, so. I had to kind of think of something, new, that's, still in kind of the same veins so. My. Question would be how. Long do you think it will be before we actually. Really. Begin to register on the scale and what can each of us as individuals do. To kind, of do. Our part, in society to push. It that way before we destroy, ourselves as a civilization. Well. On, this question I actually. Differ with. Many, other, scientists. Most. Scientists, would say that technology has. No direction. No moral, direction, science. Is a sword a double-edged, sword one. Side can cut against disease ignorance. Poverty, the, other side can cut against people I disagree. I think, technology, does, have a moral direction because. The internet spreads. Information. Information. Gives, you empowerment. Empowerment. Gives you democracy. And. Democracies. Do not war, with. Other democracies. Let's. Do a science, experiment, write. Down, every. Single war you. Had to memorize as. A child, since. You were in grade school every, single war, every. War has been fought between kings, emperors, queens. Dictators. But, never, between. Two, major. Democracies. And. So I think we are entering a, new moral. Dimension, where. Technology. Is changing. The way humans. Interact. With other humans, so, that we don't tolerate. Dictatorships. So much when. I was young in. Our history class we learned something called, dictator. For life. You. Had Russia you, had the United States if you were a pawn of Russia or a pawn of America. You were there forever, the. Only way to take you out of power is through a coffin. Dictator. And for life today. We, laugh at that, I mean, dictators. For life I mean come on right. We, have the internet, we have empowerment. We have knowledge and so, dictators. Are endangered. Species now, so. I think that technology, does have a moral, correction that I think it is liberating, it is empowering, and. It, is changing, world history, a new, chapter in world history is being written as, individuals. Make. Their mark on human. History. All. Right well, thank you all, it. Was great thank, you all for joining us. It. Was it was a lot of fun to get to talk to you about physics. And the, universe and I think this is a great audience for that because you're all involved, in technology you're, all involved, in that pursuit. Of taking us forward as a civilization, so. I hope this inspired, some interesting, questions and ideas, and hopefully. You helped take us towards that type, one civilization that, we so desperately need so thank, you so much dr. Kaku thank you.

And what the strings made of? Something can not be made of nothing...even if they find the smallest particel, even it must be made of somthing


Speed is relative, you can go beyond the speed of light..

"that's right"

I could listen to him speak all day about the universe

he said: there are planets stars and galaxies.. this is like religion.. we dont know what is out there. may be another dimension? dark matter? dimensions?

Such a pain to watch this interesting video, I'm not sure why the video is so shaky, it is definitely something you guys might want to work on for the next I/O. It happens on another videos also.

"Not great scenery" but you'll have the best view of Earth...

This man talks about future a lot ..

Avengers never discovered this

Interesting and impressive conversation

I love the concepts of reality and once understood give a greater understanding of others. It allowed me to interact with people in a much more successful manner. Knowing that someone is experiencing something they perceive as reality , even if not, that is the absolute to them. That's their reality. Don't try to tell someone their reality is wrong, because it's real to them. Approaching with the intention of attempting to align your shared reality. You're changing the shared reality while leaving their personal reality aside.

Somewhat religious

This is very random.. but interesting

We will plug our consciousness with an all-knowing Super AI

Two spinning rings perpendicular to each other and those vibrations or how they merge are the sequence of vibrations. They create sheets by spinning just like blankets etc.


"The mind of God is cosmic music resonating through eleven dimensional hyperspace ", that sounds like new age ravings.

Talking about the future of brain internet but everyone is already suffering with slow internet.

i think Dr Michio is wrong ... with the new laws that EU pass for ex. Article 17(13's new number) .. we are begining to see the wold going the other way .. this kind of thing will end in a police state .. so people need to stop thinking that our right is save ... because as robots is begin to right take jobs ... the gov. will need to control the poeple when we get 10 or 20% of people without jobs .... so we need to start finding way we can share the jobs that is jobs ... with the same pay .. as the jobs gos away and then start the move in to a new world without money when we end up with jobs ... we need to start train kids to me researchers and that kind of things..

I should be sleeping 43 minutes ago!!

Perhaps we already know all the answers, we might be looking in the wrong places.



The video recording of IO19 needs improvement. Don't use the same crew for next year. A lot of videos have shaky images and unfocused subjects

Mr. Kaku, long time no see. ( I mean on films.)

"What could be so hard?" This man took the Dark Souls approach to Physics.

Challenge accepted!


Michio Kaku is such a great man.

please sir @michokaku come to India also... please please

Does it really matter where he stays? You can listen to him from anywhere in the world.

Please, stabilize the video.. It makes me feel sick!

one of the most inspirational scientists out there, Dr Michio :D!

Good interview, Taylor. You look great! Thank you for this important video

This was fun to listen to!

Great that they found a black hole. And I also believe in the idea that our universe is a white hole of a black hole in a parent universe. Actually, the whole multiverse tree of black/white hole universes could be an ever expanding quantum computer that was the result of a technological singularity and an intelligence explosion in just ONE root universe.

The interviewer is So excited.


Welcome to the Brain-net declaration.

Always inspiring to listen to Michio Kaku...

Because of conquer land quarrels certificate quarrels and other settlement are the dangerous jobs. Not computers. I only kill don't listen to those.

This is an amazing talk. Kaku has many points.

"It would be so great if science was actually a religion!" said my 10 year old cousin. I can only imagine the depth of thought a kid would have if they are taught about science instead of holy books. Listening to this interview was so inspiring...... I am sure any person would be a at least a little bit interest to pursue science after listening to such interviews.

Japanese Dracula to rule the world! And I actually like it

I swear Michio Kaku has a script he always recites, I've heard this so many times.

this guy shouldn't express his ideas about AI and robots like he knows what's up cuz he don't. I study this area and robots don't have to feel pain to know jumping off a cliff is bad for them. And they Can be taught morals and ethics. Google Assistant can already speak to us with good manners. They can be taught. We need to Learn morals and ethics too, it's not exactly an innate thing to living things...

Michio Kaku: "We could record memories" Me: *Turning on incognito mode and setting up proxy*

"Built nuclear reactor at age 14" no big deal...

Good speak... how i wish people get liberated in their thoughts, understanding.. all humanity sooner not 100 years which dr. kaku is saying... hopefully it will happen

Nobody: ..... Dr. Michio Kaku: ROBOTS NEED TO FEEL PAIN

I don't know why every one excited about Universe!.  Everything written on Hindu Temple over 3000 years ago, In South India which is in Tamil Nadu.

opened the vid, instantly upvoted best crossover ever

you cant be the only one imaging to us because im watching what you talking about

whatever it may be in future but i see that privacy would no longer exist.

Energy and Information! Thats how Civilizations are ranked.. i wonder how I'm contributing towards a Category 1 Civilization

A black hole is caused by a big rock that gets so big it keeps light from escaping. The big rock is still there and you will become a part of that big rock if you think it might be a worm hole. Then you can really be star stuff.

Nice talk. But that camera shake will make me blind.

How all knowledge and experiments can help develope a more balance and civilized society? How science can spread a benefit to all Humanity?

They trying to make Science a religion. I think we have enough of that already.

Smart man. Shockingly naive to the dark side of human nature. The internet spreads lies just as fast as truth, and lies can evolve.

too short...

My prefrontal cortex is tickled :)

How many times has he told that particle accelerator story? Serious how many times???

Awesome insight. Truly delightful

String theory has made no predictions and it is a dead end

The spacr tine warpists did not predict the future ofvscurnce 10 years ago, because, they were not good predictors no you did it?thsnks.

a key to dark matter or no time for energy exchange short version Energy exchange limit or limit for two point to interact. it is a bit hard to write down this thought for me. if two points have relative speed more then speed of light, they not able to interact. but they can interact through the third point. (exactly like dark matter) 1)You know how space can expand faster then light? And it also can curve? soo, it most likely can curve true it selfe. and this how it not interacting with it selfe. (in black holes space curveture length is extremely small) 2) How many time need for Sun to exchange energy with you? soo every energy exchange take some "time". There for if two point have speed difference more then C, they will have no "time" to exchange energyx, have no "time" for exchange to occure. Even if they will share same place. also you may see it as, FLT parts in more then one place at a "time" compare to us. For FLT part we in less then one place at "time". (why mass go up) it more about interaction limin then about speed of light. can be tested, if we will represent a third point. long version -dark matter in our galaxy, (most likely particles emitted by central black hole) is particles that moving faster than light. (most likely you do not "belive" in this) if i assume it is correct, then big amount of hydrogen on edge of galaxy, is where this "dark matter particles" decay after losing speed. (decay like new particles from hadron collider) -parts of dark matter alredy found, but we do not about it. (perseption(particles from hadron collider)) -particles found with hadron collider behave like a dark matter after loosing speed. -most likely there is a energy exchange speed limit in betwen two points (not sound speed), most likely it is a speed of light. (that about why we do not see dark matter, but see it interction with other(slower for it/faster for us) particles) -particles from hadron collider will be stable if placed in faster then light speed. whant to tell more, I hope this is enough to contact me. the key is a energy exchange speed limit (i want my Nobel for showing you dark matter) Best regards, Dynin A.I.

i work with ai most of time now, when with it my iq goes up to 200. just information and illusion done by off and on machine

in reality god do not exist, probability says he exists

mind of god is more stable than cosmic music resonating through 11 dimention

god did a horrible thing when he created us

The first "Moonlanding" was fake, we are not "Returning" to the moon. They never been to the moon how could "Nasa Forget the technology and now it is coming back?" Zero logic. Neil, and many other Austronauts confirm they never been to the moon.

Animals feels pain too.. We need to wake up to our companions of earth and stop consuming/thinking of them as "food"

What a bunch of hooey. It’s a Hologram. There is no “nuclear” and the future is what you want it to be, You Are the Universe staring at a Hologram

There's a lot of heavy stuff Mr. Kaku just said. I'm scared and excited at the same time

1st time I've heard it, but it feels totally scripted. Very distracting for me.

Do we REALLY not yet have the capability to mine the oceans and control the weather? Like as in not yet publicly accepted or what?

Dark matter is in the black hole. .. you guys aren't thinking big

Michio Kaku talking about robots replacing repetitive job is relating to Detroit: Become Human.

Awesome video!!!!!!

well unicorns do exist but aren't horses


And he's so optimistic about good technological cybernetics. Thumbs up.

Based on the comments I've seen so far, barely any of you can watch a video for more than a few minutes before judging it.

Humanity has no future at least not anymore we humans are heading for extinction and total destruction no matter what our time here on earth is coming to an end and probably within the next 30 years.

And not even a boring second. Very cool talk by Kaku!

i d like to know what a flat earth believer think about this LOL...

Too bad... symphonies don't happen by evolution or big bangs.

"democracies do not war with other democracies" is a completely historically inaccurate statement.

I can repeat what others have said also.

The professor is correct. Once we can harness the energy freely, man will not fight because energy is free

What a shame this man that has the ability to tell the physics in a such fun way but only relying on the god-non-sense stuff. I couldn’t stand it anymore.

The last time I heard a discussion of string theory was in the mid 80's. It did not make sense to me then, nor does it now. (speaking intuitively, of course).

The humour physics brings to the world is astonishing.

Hindu religion said it..that our whole body made up just string of music...damn ...why ppl still not notice it. that's..hindu religion already said it

Knowing that most of what he said is scripted, but it is still very chilling and inspiring to hear him say it.

Sold out.

Thanks Kaku.

Science makes me a believer in its creator!

I have had these theories for over 30yrs without having a sheepskin. You folks are just catching up to me. Mr. Kaku I would find working with you to finish the ultimate theory my gift to humanity call me I would bet we are on the frequency, if you understand this then i will hear from you.

Begin anew... from scratch. Too late for this Civilization.

im in a very strange mood... i have a question to do with the state dependent theory of cognition, from psycology: if all future experience is conditioned by the past, and if we are having a crisis of consciousness, which i think is hard to deny at this point, might we be able to construct a theoretically tenable baseline of shared common somatic memory and by non local interferance beams, download an awareness of potential futures into the brains of all humans, a la total recall, to guide humanity toward positive potential futures, while mitigating the risk of negative ones, while at the same time forming a completely visceral and tangable emotional bonding between all of the human race, with the help of quantum computers and the theoretical frameworks of asmr and coherer technologies? im genuinely currious, is this possible? thanks. :)

What a combo ! Kaku and Taylor

im in a strangely peculiar mood and id like to share an anecdote. i was very young, maybe about 4 and was feeling deeply contemplative about logic and physics. i had just recently come to a deeply personal conclusion about opposits containing each other and being in a funny way identical, and was fooling around with the temperature knob in the bathtub, and noticed that the very hot setting and the very cold setting produced an distinctly similar sensation of numbness on my skin, which, based off my earlier conclusions, let me to theorize that perhaps temperature was circular, and that perhaps the most extreme heat actually went right past hot back to absolute zero. i dont know if what im saying has any theoretic validity, or even why exactly im sharing this, but it was a deeply personal experience i held onto for a very long time. love your work. :)

michio, no disrespect, but there are certain distinct phenomena that string theory cannot acurately represent compactly or intelligably, like the epicycles of history, human consciousness,or even black holes themselves. ive jokingly stated that such nonlinear self recursive phenomena could be theoretically represented by adding a yoyo to the end of your strings, but maybe im Not joking. i certainly dont have time to work on that kind of mathematical framework. we both definitely agree, though, on the triune nature of vibration being completely fundamental. although, i do wish that you would have come up with at least ONE new popular metaphor, or published SOMETHING readable i had access to over the past ten years. all jokes aside, you've done a great service to the feild. all this new black hole physics is extremely exciting. to infinity and beyond. :)

10 billion dollars for another god-damn subatomic particle LMAO

i have a very serious question about consciousness and physics i was not able to ask in person, but want an answer to, anyways. if one was able construct a completely believable alternate reality of pure imaginaion with ones own consciousness and travel there in a dream state, would it be real, could you stay there, and what would happen to real reality? thank you. :)

i respect scientists, but one thing i cant tolerate about theme is their tendency to view ordinary humans as animals and subjects, forgetting that they themselves are human.

What Kaku explains around 32:00 is what makes me want to become a scientist and pursue multiple masters degrees after i finish my (currently f1/4 finished) B.S. degree to educate the world and inspire millions to be explorers

Brilliant talk, thank you

It’s 10:24:36. Gonna be sleeping in 40min

Thank you


We probably in A black hole in sole level and we look At black hole with another dimension !

I don’t think we need to wait that long to reach the future those physicists mentioned. Just CGI every knowledge that we already know. What is the different if we see the same thing when we are in space to when we use CGI and virtual reality. It cuts lots of cost and risks. And yes the aliens came to Earth long time ago (look into those ancient temples). Without aliens technology, it is impossible to build such things. Yes democracy is ideal but democracy doesn’t have a congruency which lead to nowhere. Dictatorship is harsh but it get the jobs done fast. I think we should first clean up our house before going to look for someone else’s cribs. Trillions of dollars that spend on the journey to someone else’s house could be spend on fixing our own. We need ocean clean up, air clean up; etc. The rich should help straighten out the poor, unless they plan to live in others’ homes. After all, we share the same house so far.

The bh spits the matter out in heavan and its turned into our future home

Ask him how much of the milkay way has been eaten by the the sagetaris super massive black hole ?

Keep dreaming!

hands down

God is a Musicien


I think he is a bit too optimistic about the war part...

Oh, no. I was not expecting a recent Dr. Kaku interview to begin with so many speculations about black holes, speculations which appear to be professed as if these are known scientific truths. Sigh. Even after all these decades, Dr. Kaku unnecessarily blurs science with sci-fi. The viewer is then responsible for doing the necessary tedious work of separating the wheat from the chaff. Sigh.

yeah... hopefully we don't die of climate change and plastic pollution before all that...

Michu has something against rap music

Stabilize, dammit!1

YouTube to censor this video. Too much science!

Nicely explaination. i thing in sub atom particle the distance electron and proton very litle and in the end is empty space

The host is so smart asking smart questions that we've easily understand Props for him

Nasa has to reveal all their secrets that belong to humanity. thanks for the updates.

Shaky Video!!! Anyway thank you :)

The best interview of Dr.Kaku to date

Mr.Kaku: Talks about great concepts in details Interviewer: That's.... Interesting

Who is sponsoring Michio Kaku?

..I always wondered in school (university) where does the 1/x and -1/x graphs( and the likes) go too? Surely, it's a ball or a 3D object, that we looking at, thinking in 2D? There must be a point, that it reaches zero. Then, curve inwards to another axis.( " parallel " university ) or curve outwards, because the axis line still is moving, and there has to be a point - somewhere - where it flips. Yip, and that's why I never pass maths or physics... Require $60 per month( for 12months only) to study more, at my own slow pace. Thank-you.

i think Dr. Kaku should meet Indranu Suhendro. seriously, he got the theory that black hole is has another side. they can sharing about it

Maybe in Civilization3.
