Michio Kaku: “The Future of Humanity” | Talks at Google


[MUSIC PLAYING] SPEAKER: So I
think before we get into some of the exciting things
that come up in your book, today was a pretty
big day in astronomy. There is some news
about a black hole. Can you talk about that? MICHIO KAKU: Yes. A black hole is a
cosmic roach motel. Everything checks in,
nothing checks out. And we photographed this. This is incredible. History was made
when we actually showed a photograph of
a gigantic black hole. It weighs six and a
half billion, with a B, billion times more
massive than the sun. It is 55 million
light years away. It is a gigantic monster. And it’s sort of like a unicorn. We physicists knew at some
point this exotic object would be found. Einstein’s equations
predicted it in 1916. We’ve known for a hundred
years that a black hole could be lurking in the
heavens, but we finally– we finally photographed it. And it was revealed
this morning. Next, in a few weeks,
we’ll reveal the black hole at the center of the
Milky Way Galaxy. So tonight, when you go
outside, look in the direction of Sagittarius. There’s a raging black hole in
the constellation Sagittarius, in the center of the
Milky Way Galaxy. It weighs about two to
four million times more massive than the sun. And it’s in our backyard. So children ask the question– if the moon goes
around the Earth and the Earth goes
around the sun, what does the sun go around? And the answer
is– a black hole. SPEAKER: So you talk about
children asking questions. And you’ve talked
about that you had a moment when you
were growing up, of what sparked your
interest in science. MICHIO KAKU: Yeah, when
I was eight years old, something happened which
changed my life completely. They made the
announcement, when I was in elementary school, that
a great scientist had died. And they flashed a picture
in the newspaper of his desk. And on the desk was a
book, an unfinished book. And the caption said, this
is the unfinished manuscript of the greatest
scientist of our time. So I was eight years old. I said to myself, why
couldn’t he finish that book? It’s a homework problem, right? Why didn’t he ask his mother? So, I went to the library. And I later found out his
name was Albert Einstein. And that book was “The
Theory of Everything.” He wanted an equation no
more than one inch long that would allow us to,
quote, “Read the Mind of God.” So I said to myself,
wow, that’s for me. I want to work on this
theory of everything. And in fact, that’s
what I do for a living. I’m the co-founder
of string field theory, one the main
branches of string theory. And we think that that is
the theory of everything, that everything we see
around us is nothing but vibrations of tiny strings. Each subatomic particle is a
note on a vibrating string. What is physics? Physics is the harmonies we
can write on vibrating strings. What is chemistry? Chemistry is the melodies we
can play on vibrating strings. What is the universe? The universe is a
symphony of strings. And then what is
the mind of God? The mind of God is
cosmic music resonating through eleven
dimensional hyperspace. That is the mind of God. SPEAKER: I think
for all of us who are not theoretical
physicists in the room, we appreciate that clarifying
explanation, really elegant metaphor as well. One of the things
that I found when I was sort of thinking about
questions that I might want to ask you, or that
might be interesting, is that, in looking at
the breadth of your work, it’s really hard to
know where to start, because your work spans an
incredible range of fields from the history of
astronomy, to string theory, to theories of consciousness. And so I was going
to ask you, what do you feel like is at
the heart of your work? If your body of work
were a solar system, say, what would be the
sun at its center? MICHIO KAKU: Well,
when I write books, I write for myself as a child. Because when I was a child
going to the library, I would look up things
like the fourth dimension, like anti-matter, like
parallel universes. And there was nothing,
absolutely nothing in the library for
a young kid who wants to know about all
these fantastic things they see in the movies. So I said to myself,
when I grow up, and I become a professor
of theoretical physics, and I work at the
unified field theory, I want to write for
myself, as a child. And then when I
was in high school, I decided to put
this into motion. So I went to my mom one
day, and I said, mom, can I have permission to build
an atom smasher in the garage? SPEAKER: As one does. MICHIO KAKU: Yeah. I grew up in Palo
Alto, where a lot of young people in their
garages built machines. So I built a beta-tron
particle accelerator. I got 400 pounds of transformer
steel, 22 miles of copper wire, and I built a
6-kilowatt, 2.3 million electron vol beta-tron
in my mom’s garage. I plugged it in finally. I closed my eyes. I shut my ears. And I heard this
huge crackling sound as 6 kilowatts of raw power
surged through the capacitor bank. And then I heard this
pop, pop, pop, sound, I blew out all the
circuit breakers and fuses in the house. So my poor mom, she’d come
home from a hard day’s work and say to herself,
why couldn’t I have a son who plays baseball? Maybe if I buy
him a basketball– and for God’s
sake, why can’t you find a nice Japanese girlfriend? Why does he have to build
these machines in the garage? But it earned the attention
of another physicist. A physicist took
an interest in me at the National
Science Foundation– at the National Science
Fair in Albuquerque. And he arranged for me to
get a scholarship to Harvard. His name was Edward Teller,
father of the hydrogen bomb. SPEAKER: And from
then to now, how do you feel like the course
of your career has changed, or what– have your interests
shifted since then, since that beginning
of you want to solve the theory of everything? MICHIO KAKU: Yeah,
that’s still the goal. But as a hobby I like
to read science books. I’m a science junkie. And I have the privilege
of interviewing hundreds of scientists for
BBC Television, the Discovery Channel. And whenever I interview these
scientists– about one a week, for my radio show and TV– I always ask them
the key question, the question of all questions. And that is– is there
intelligent life on the earth? Well, I was watching the
Kardashians on TV last night. And I’m convinced that
there’s no intelligent life on this planet. But maybe in outer space,
maybe in outer space there’s intelligent
life out there. SPEAKER: So, in
your book, you talk about how we might leave
the earth to possibly meet intelligent life elsewhere. MICHIO KAKU: And we may have to. The dinosaurs– the
dinosaurs did not have a space program and that’s
why they’re not here today. That’s why there are not
dinosaurs in this room, because they didn’t
have a space program. But we do have a space program. And prices are
dropping every day. Things are getting cheaper. Silicon Valley billionaires
are writing checks. And, for example, how many
people in this room have seen the movie, “The Martian”– raise
your hand– with Matt Damon? Whoa. That movie cost $100 million. But the Indian government sent
a probe to Mars for $70 million. So a Hollywood movie
about going to Mars costs more than
actually going to Mars. That’s how much
prices have dropped. And rockets are going to
be reusable in the future. When we commute to work, and you
drive your car to work and park the car, do you junk your
car and sell it for scrap after one trip? That’s what we do
for rocket ships. We take one trip in a rocket
ship and dump it in the ocean. You’d bankrupt the
world if every car had to be junked after one ride. That’s going to change the
economics of space travel when we have reusable rockets. SPEAKER: So, one thing I
like about your book is you’ve structured it as sort
of like, we’re starting with, how do we get off the planet? How do we colonize
our solar system? And then how do we think
beyond that and beyond that? So, when someone
asks you, like, well, how close are we actually
to living on Mars, how do you answer that? MICHIO KAKU: Well, first of
all, we’re going to the moon next year. After a 50-year gap,
the SLS booster rocket is going to be fired up and
we’re going to go to the moon. And not only that, there’s
going to be a traffic jam around the moon, because
Elon Musk has his Falcon Heavy rocket capable of going not
just to the moon, but Mars. He has sent a Tesla sports
car on a trajectory to Mars. And then we also
have the richest man in the world, Jeff Bezos– or the former richest
man in the world– he has the Neil
Armstrong rocket. And then the Chinese have
the Long March rocket. We’re going to have a
traffic jam around the moon pretty soon. And I think our grandkids– our grandkids may
have the option of honeymooning on the moon. The moon is– the moon
is only three days away. It’s a hop, skip, and a jump. SPEAKER: So the moon is closer,
Mars is a little bit farther. So, you talk in your book
about also possibly colonizing some of the moons around
Jupiter and Saturn. How do you imagine
us getting there? How far– I mean, is this within
our generation, our lifetime? MICHIO KAKU: Well
starting next year, we’re going back to the
moon with an unmanned space probe that will orbit
around the moon. Around 2023, humans will
go back to the moon. And so we’ll begin the process
of making the moon a base, to eventually go to Mars. And then SpaceX already has the
preparations for a Mars rocket. It is a huge rocket, the
biggest one ever conceived. It’s called the BFR,
the biggest rocket. B for Big, R for Rocket,
and F for your imagination. It’s already being built.
So we’re already laying out the steps to go to Mars. And when Elon Musk was
a high school student, he read the book,
“Foundation” by Isaac Asimov. How many people have
read the “Foundation” series by Isaac Asimov? Then you know that that
is a dream of becoming a multi planet species. It’s not going to
happen anytime soon. But we begin the process of
terraforming Mars perhaps in this century. SPEAKER: I love how you talk
a lot about science fiction and that there’s– that science
fiction has both inspired and predicted some of the
technological advances that we’ve seen and some of the
things that we learn about our universe. Do you have a favorite
anecdote or story of where fact and
fiction have intersected? MICHIO KAKU: Well, I’m on radio. And people call me. And many times people say,
professor, you’re wrong. You’re wrong because the
aliens are already here. They’re not in outer space. They’ve already landed
with their flying saucers. So, I tell them,
well, how do you know? And they say, well,
they’ve been kidnapped, kidnapped by flying saucers. So if any of you have
ever been kidnapped by a flying saucer, for
God’s sake, steal something. There’s no law
against stealing from an extraterrestrial
civilization, no law whatsoever. Steal anything– an alien
chip, an alien hammer, an alien paperclip,
anything, so you have bragging rights about
going into outer space on a flying saucer. SPEAKER: I like that idea. Noted. Not that Google endorses
any kind of that activity. MICHIO KAKU: But there’s
no law against stealing from an extraterrestrial
civilization. SPEAKER: Should there be? MICHIO KAKU: No. SPEAKER: No. So what are the– once
we’ve established a presence within our solar system, and
we know how to get around, what’s beyond that? MICHIO KAKU: Well,
already we physicists are looking at starships. NASA has a 100 year
starship program. My colleague, the
former Steven Hawking, already was responsible for the
break through Star Shot program to send the first
starship to a nearby star. It would be the size
of a postage stamp. It’s a chip with a
parachute, inflated by a bank of laser beams,
which would accelerate it to 20% the speed of light. And it would reach Alpha
Centauri in 20 years. And so we are talking about
the first microchip starship to take us to the heavens. And then we physicists have
looked at Ram jet fusion engines. Fusion engines– of course,
we don’t have them yet, but one day we will– Ram jet fusion engines
require no fueling whatsoever. They scoop up hydrogen in the
forward direction like an ice cream cone, burn interstellar
hydrogen in the engine, and run forever with no
refueling whatsoever. That’s the Ram jet fusion
engine, which could possibly take us to the nearby stars. And then even
beyond that, there’s a possibility of maybe
using a black hole. And, of course,
just this morning we had the first picture ever
of a black hole that’s been revealed to the public. And what is a black hole? A black hole is a
cosmic roach motel. Everything checks in,
nothing checks out. And we photographed it. And there’s a
controversy as to what’s on the other side
of the black hole. Some people say nothing. Things just fall in, and
that’s the end of the story. But if you look at
the mathematics, we have an exact solution
of Einstein’s equation, given by Roy Kerr in 1963,
of a rotating black hole. A rotating black hole does
not collapse to a dot. That’s the old
fashioned thinking. It collapses to a ring,
a ring of neutrons. And if you fall through the
ring of neutrons vertically, you wind up in Wonderland. You wind up on the
other side of forever. It’s a gateway to a wormhole. And if you fall
through a second time, you wind up on a second
parallel universe. So it’s sort of like hitting
the up button of an elevator. You have different floors. Each time you go to a
different floor, every time you go through the gateway. And then the question
is, is that a solution of Einstein’s equations? And the answer is, yes. What’s the catch? There’s always a
catch someplace. And that is, we don’t know
how stable the wormhole is. That requires us to
go beyond Einstein. Einstein’s equations give
us rotating black holes, where there’s a gateway
to a parallel universe. That’s Einstein’s theory. However, we don’t know whether
radiation effects, as quantum effects, will destabilize it. That’s where string
theory comes in. String theory is
a quantum theory. Now we can calculate
quantum corrections and calculate the
stability of the wormhole, but that is still an
active area investigation. And then the question is, if
you go through the wormhole, can you go backwards in time? And the answer is, yes. These things are potentially
time machines as well. And then the question
is, what happens if you go backwards in time meet
your mother before you’re born, and she falls in love with you? Well you’re in deep doo
doo if that happens. But yeah, the quantum theory
does make possible the fact that you might be able to
build a time machine if you can stabilize the Kerr metric. SPEAKER: Did we have
anyone who wanted to ask Professor Kaku any questions? AUDIENCE: Hi, so, I wanted
to ask about string theory specifically. And one of the things that I
understand about string theory, is that it’s proven very
difficult to find tests, to find out whether
string theory is actually the way the universe
works, or maybe there’s some other way that
the universe works. And I wanted to
get your thoughts on that in sort of a
philosophical level. Do you think that
you eventually will discover some aspect of string
theory that will be verifiable? Or do you think that
we’re sort of destined to have to guess at
some level of what’s going on at the very most
basic levels of the universe? MICHIO KAKU: Well,
first of all, we have the mystery of dark matter. Dark matter holds
the galaxy together. And that’s why we’re here today. If there was no dark matter
holding the galaxy together, the galaxy would have
disintegrated billions of years ago, and we wouldn’t be here
to talk about this question. And then, what is dark matter? It is invisible
and it has gravity. If I held it in my hand, it
would seep through my fingers, go right to China, reverse
direction in China, and oscillate between
here and China. And then what is it? The leading candidate
for dark matter is the photino, the next
octave of the string. We are the lowest octave
of vibrating strings. We can fit protons,
neutrons, electrons, using a very low energy
approximation to string theory. But string theory has
higher vibrations. The next vibration
up is the photino. Photino has mass. It has gravity, but no
electromagnetic interactions. It’s stable. That, we think, is dark matter. And we hope to create
it with the Large Hadron Collider or the next
generation beyond that. Already, the Japanese, the
Chinese, and the Europeans are proposing the next step
beyond the Large Hadron Collider. The Japanese have the ILC. It’s a linear accelerator. The Chinese are also proposing
a linear accelerator. And even CERN is proposing the
next generation beyond that. We may find dark matter
in the laboratory, and that could clinch
it right there. AUDIENCE: Thank you. AUDIENCE: Hi Professor, what
are your thoughts on quantum computing and the future of it? And how long you
think Google will be able to deploy a quantum
computer into our data center? MICHIO KAKU: Well, as you know,
Moore’s Law is slowing down. Moore’s Law is the reason
why we’re here today. If it wasn’t for Moore’s Law,
there would be no Google. But it is slowing down. And it’s bumping up against
the quantum principle. Right now, your Pentium chip
has a layer about 20 or so atoms across at minimum. In another 10 or so years,
if you just extrapolate, it’ll be five atoms across. When you hit five atoms
across, all hell breaks loose. The Heisenberg Uncertainty
Principle takes over. You don’t know where
the electron is anymore. You get leakage. And you get heat generation,
so much that you could for an egg on a microchip. Moore’s Law is
already slowing down. You can talk to any
physicists, we’re beginning to hit
the quantum limit. So we have to go beyond silicon. In other words, Silicon
Valley could eventually become a rust belt, like
the Rust Belt of Pittsburgh. Eventually, yes, Silicon Valley
could become a rust belt, and we had to go to
the post silicon era. We have to go to
photonic transistors, molecular transistors, protein
transistors, DNA transistors, atomic transistors,
photonic transistors. We physicists are looking
at all sorts of alternatives to silicon. But there’s a catch. None of them are ready
yet for prime time. I will put my money on molecular
transistors, like graphene. We can make a transistor out
of a single atom of carbon. That’s pretty good. But we cannot machine it. We cannot mass produce it. We cannot engineer it. It’s a technical problem. Quantum computers are
even worse because of the de-coherence problem. I was in Moscow just
a few months ago. I actually met with Medvedev
and the leader of Alibaba. And yeah, everyone’s working
on quantum computers. The Russians are, the Chinese
are, we are, of course. But there’s a
problem, de-coherence. Every time someone
sneezes in a block away, the coherence of your
quantum system disintegrates. So I’m not saying
we can’t do it. I’m saying it’s
probably decades away. The turning point is 50 qubits. If you hit 50 qubits– quantum bits– then you
could surpass any known digital turing machine. But how do you go
beyond that yet? We don’t know because of
the de-coherence problem. I have friends upon– I have friends working on this. This is a multi-billion
dollar question. There’s going to be
a new Silicon Valley. A new Silicon Valley emerging
from all this, probably a quantum valley, and
it’s up for grabs. Nobody knows what’s
going to replace silicon. AUDIENCE: Thank you. AUDIENCE: Hi, Professor. I wanted to ask a general
question about projecting or predicting into the future. So, generally, when sci-fi
writers or futurists try to predict into
the future, they’ll look at the state of
technology or the cutting edge around them, or in
the last couple of years, and they’ll try to
extrapolate forward. We’ve already seen that,
like back in the ’60s, people were predicting that
by now we’d have flying cars, and hoverboards, and we’d
be vacationing on the moon. And instead, we’re sending
cat pictures across the world. So, when you’re predicting
out into the future, how do you– how do you account for
that kind of uncertainty? How do you have confidence
in your predictions? MICHIO KAKU: Well,
first of all, people forget that when they
look at flying cars, that was a creation
of cartoonists. Most people’s understanding of
the future comes from cartoons. I’m a physicist,
not a cartoonist. We knew that flying cars would
be hard to do, but possible. In fact, I was just
in Dubai last month, and we are going to
have flying cars. Dubai is already
in the final stages of signing contracts for
a fleet of flying cars. So yes, flying cars are coming,
but hoverboards are not. Hoverboards would violate
the Quantum Principle. We do not have anti-magnetism,
because the anti particle or the photon is the
photon, therefore there’s no such thing
as anti-magnetism, or even anti-gravity,
that Michael J Fox can use to scoot across a wooden floor. And so, we’re not going
to have hoverboards, but we will have flying cars. Now, I’m a physicist. When I try to
project the future, first I look at Moore’s Law. So I see where we might be
in the coming decades, OK. And I realize that yes,
artificial intelligence is coming, but we’re
going to hit a brick wall at a certain point,
or perhaps a problem when Moore’s Law is
eventually sealed off and robots are not going to
become arbitrarily intelligent. But I’m a physicist. I realize that with
ingenuity we could make them smarter and smarter. For example, right now, our most
advanced robot, or one of them, is ASIMO. You’ve probably seen him on TV. It’s like a little
boy who can run, walk, climb up stairs, dance. And I interviewed the creator
of ASIMO for BBC television. And I asked him, how smart
is the world’s smartest robot, your robot, ASIMO? And he was very frank. He said that ASIMO has the
intelligence of a cockroach– a retarded cockroach– a
lobotomized retarded cockroach. But I could see that, yeah,
you could extrapolate. Eventually, they’ll be
as smart as a mouse, then as smart as a rat,
then as smart as a rabbit, then as smart as a dog and
cat, and then maybe as smart as a monkey. Now, at that point,
like in science fiction, I think they could be dangerous. I think Elon Musk is right,
but in another 100 years. Because monkeys are self-aware. They know they’re monkeys. They’re potentially dangerous. But dogs, dogs are confused. Dogs think that we are a dog. We’re the top dog and that’s
why they slobber all over us. They haven’t quite
figured it out yet, that we’re not really dogs. But monkeys, they
have self-awareness. So how long will it take
before we get robots with self-awareness? I think maybe by the
end of the century. At that point, I think we
should put a chip in their brain to shut them off if they
have murderous thoughts. But again, going to the next
century, the 22nd century now, robots will become
self-aware and they’ll remove the chip in their brain. Then what do we do when there
are no more fail-safe systems? At that point, I think we
only have one alternative. In a 22nd century, I think
we should merge with them. Why not become super
man or a super woman? Why not rule the universe by
merging with our creations? That’s not going to
happen anytime soon, but I’m just simply
projecting Moore’s Law, projecting known physics
into the next 200 years. AUDIENCE: OK, thank
you very much. AUDIENCE: Thank
you, Professor Kaku. And I have to say that
I’m a big fan of you, and I’ve read many of
your previous books, and looking forward
to reading this one. And based on– based on
my previous readings, you believe that humans
have a very bright future. With the advancement
of technology, we’ll gradually conquer the
solar system, and Milky Way, and beyond. But there is the other
stream of theories like, they are
really pessimistic on the human future. Like, for example, the
giant filter theory, and the great filter theory. Basically, they say that any
advanced civilizations will– as they develop,
will sooner or later encounter some
very big obstacles. They call it filters. And be it like meteorites,
or the nuclear war, or the advanced of the double
edged sword, the technology. So what’s your take on this? Can we humans really
avoid this to happen? MICHIO KAKU: Can
we humans do what? Do you understand? SPEAKER: Yeah, so I
think the question– and correct me if
I get it wrong– but I think it’s about that you
have a really optimistic view of the future. But there are parties who don’t
have such an optimistic view, that believe that we’ll succumb
to some great catastrophe. Is that kind of the gist of it? AUDIENCE: The great
filter theory. They say we will become– MICHIO KAKU: OK, well, let’s
take a look at the long view. I’m a physicist. And we like to quantify things– dangers, as well as progress– on the basis of two things–
information and energy. That’s how we
parametrize the future. When you parametrize the
future in terms of energy, we rank civilizations by type
one, and type two, type three. A type one civilization
is planetary. They control the weather. They control the oceans,
volcanoes, earthquakes. Planetary civilization
controls planetary energy. Eventually, they exhaust
the power of planet and begin to play with stars. They create Dyson spheres. They play with– they
colonize our solar system. That’s type two. For example, “Star Trek”– “Star Trek” would be a
typical type two civilization. Then there’s type three. Type three is galactic. They roam the
galactic space lane. They play with black holes. And “Star Wars” would
be a typical type three civilization. And then, by the way, I was
giving this talk in London once, and a little
boy comes up to me– 10-year-old boy– and the boy
says, Professor, you’re wrong. You’re totally wrong,
there’s type four. And I was kind of tempted to
say to the kid, shut up, kid. I was polite. I said, look, there are
planets, stars, and galaxies. That’s all there are. There’s no type four. And he insisted no,
Professor, there’s type four– the power of the continuum. Now who’s a “Star
Trek” fan here? What is the only type
four civilization on network television? The Q. That energy is dark energy. There is an energy source
even bigger than galactic. Dark energy is the
energy of the Big Bang. It’s the
anti-gravitational force that’s creating the
expanding universe. So then the question is, where
are we on this scale of energy? Are we type one, that
play with the weather? Are we type two,
that play with stars? Are we type three, that
play with black holes? No, we’re type zero. We get our energy
from dead plants. But we can calculate when
we will become type one. And the answer is, in 100 years. Around 2,100, we will
become planetary. Now, we see that everywhere. What is the internet? The internet is the first
type one telephone system. The first type one technology
to fall into the 21st century. That is what the internet is. What language will the type
one civilization speak? Well, already on the internet,
English and Mandarin Chinese are the two– number one,
number two languages. We see the beginning of a type
one economy with the European Union. We see the beginning
of a type one sports with soccer and the Olympics. We see the beginning
of a type one fashion with Chanel and Gucci. We see the beginning of a
type one culture spreading throughout the planet. But as you pointed out, there
are dangerous things facing us. A type two civilization
is immortal. Nothing known to science can
kill a type two civilization. Asteroids could be deflected. The weather can be altered
so global warming is not a problem. Type two civilizations
are immortal. The danger is type
zero to type one. That is the most dangerous
transition of all, because we have all this
sectarianism, fundamentalism, racism, whatever
coming from the swamp. We just emerged from the swamp. And we’re reaching for type one. Every time I read
the newspaper, I see the birth pangs of
a type one civilization. All the headlines, all
the controversies, I see are the birth pangs of the birth
of a planetary civilization. And it’s not guaranteed
we’re going to make it. I think we will, but
there’s no guarantee. AUDIENCE: Thank
you, very inspiring. AUDIENCE: Hi, Professor. Thanks for coming
to talk to us today. There’s a book series called,
“The Three Body Problem,” that I’m not sure
you’re familiar with. It basically presents
humanity’s first encounter with extraterrestrials. And sort of the
intergalactic diplomacy that the book sort of advocates
for is this preemptive strike. It says that the only way
to stay safe in our universe is, as soon as we identify
other intelligent life, you have to destroy
it right away. I was wondering if you
would agree with that, and how you would
recommend we navigate these intergalactic
relationships, potentially in the future? MICHIO KAKU: Well, if you’re
walking down a country road and you bump into an anthill,
do you go down to the ants and say, I bring you trinkets? I bring your beads. I give you nuclear energy. Take me to your ant Queen. Or do you have this
politically incorrect urge to step on a few of them? And then the ants, do they have
the idea that they can launch a pre-emptive strike
against humans by flinging their weapons– little
kernels of rice– at us? So, like I said, if they can
reach us from outer space, they’re probably type two, or
more than likely, type three. At that point, they already
have mastered starships. Type three, you can
access the Planck energy. The Planck energy is
the energy of which space and time become unstable. In other words,
wormholes become possible for a type three civilization. You take out a
calculator and calculate. Growing at 3% per year– a modest growth in energy– how long before we
become type three? In 100 years, we’ll be type one. In a few thousand years,
we’ll be type two. In about 100,000 years,
we’ll be type three. And 100,000 years is nothing,
nothing on a cosmic scale. By the time you’re type
three, you have access to the Planck energy. Space and time become unstable. Bubbles begin to form. You can heat up space so
that bubbles begin to form. These bubbles are gateways,
gateways to other universes. And you’re going to
have a preemptive strike against these people? I don’t think so. Now, are they going
to be dangerous? Well, I think we
have not too much to fear from them,
because what do they want? Do they want to
plunder our resources? There are lots of dead
planets out there, like Mars, that they
can plunder at will. So, I think that there’s
really no reason for them to plunder the earth,
because there’s plenty of uninhabited
planets out there to plunder. And for the most part, what
do we have to offer them? If you’re going to
a forest and you meet the deer and the squirrels,
do you talk to the squirrels? Initially, yeah. Good boy. Yes, you talk to the squirrels. But then you lose
interest because they don’t talk back to you. And even if they did
talk back to you, do they have a preemtive strike
by throwing acorns at you? So I think that on that
scale, if they can reach us from another star, they’re
already type two, or more than likely, type three. AUDIENCE: Thank you, very much. AUDIENCE: Do you think we
will ever leave Earth forever? MICHIO KAKU: I
think at some point, we may have to leave
the Earth forever. In five billion years,
the sun will expand. The mountains will melt.
The oceans will boil. The sky will be on fire and we
will have the last nice day. We have to. Five billion years from now–
it’s the law of physics. Physics is a death warrant
for intelligent life. And in fact, 99.9% of
all lifeforms go extinct. How do we prove that? Just dig right under your feet. Right under your
feet are the bones, the bones of 99.9% of all
species that have ever existed on the planet Earth. Extinction is the norm for life. We forget that. Extinction is the norm. We have a brain. We can control our destiny,
but most animals cannot. And so we forget the fact
that extinction is the norm. So it’s not a
question of if, it’s a question of when we
leave the planet Earth. There’s no choice. It’s the law of physics. AUDIENCE: Thank you. SPEAKER: Thank you all
so much for coming. That’s the end of our talk. And we are just so grateful
to have had you here. Thank you, so much. MICHIO KAKU: OK, my pleasure. [APPLAUSE]

  1. He is really pretty nice physicist. He can explain complicated theories in very simple words. It is extremly hard skill of scientists.

  2. Extraterrestrial civilization are sent by God, and they are billions times smartest than you. Whatever God creates must necessarily be less than He. The created can never be greater than he, or as great as the One who made it.

  3. The distorted audio quality of the talk surprising given the nature of the amazing speaker Michio Kaku & amazing topic Space Astronomy Science & Truth about Reality!

  4. You mean after all that were just gonna go extinct?

    I wish they would have told us about Tesla and what he was up too when we were in school because it seems to me he was way ahead of the brains of today. The electric universe, ether the space in between the space is it static or dynamic? Because if its dynamic and we know that it is then it has the potential for near limitless power. And Tesla intended to give that power to humanity for free. Tesla said Einstein was a nice man but he was wrong about the Universe and how it works totally wrong. Tesla believed in practical experiment not theories and he is the Father of the science thats been driving us forward. He said it didn't bother him that people stole his ideas he said what bothered him was they had no ideas of their own.

    The difference between Tesla and what rules our world today is his love for humanity and his desire to help all people while those that rule our world today care only about money and power and making all people slaves to their lies and bullshit.

  5. when there is the final expansion into oblivion, how would we survive if theres no energy to feed from?

  6. as far as I am concerned, I find it paradoxical that you speak of human beings as a race of clones and even more incredible is that you censor my every request and idea of ​​emancipation from your inhuman system of which I do not want to be a part and then adopt other cervical solutions based on addiction and On the annihilation of the organic life of this planet, desertification seems to me sufficient proof

  7. Respect you Dr. Michio Kaku. I wish you live a long life & continue this ground breaking research & inspire others.

  8. He is always telling what he built in his parents garage, so repetitive. He is light years away from Dr.Carl Sagan's style and class

  9. WHAT ARE YOU DOING??? THERE ARE YOUNG ADULTS HERE. THEY HAVEN'T LIVED AND YOU ARE FEEDING THEM ALL THIS NONSENSE. I PRAY THE LORD COME NOW!!!

  10. God is a physicist, and holds the most energetic and smallest consummation of destinies fractal. When all cosmic beings are sufficiently aware, God will stop shielding that fractal. All medical doctors, nurses, intelligent architects of the best buildings, the most fantastic apparatuses for learning, travel, creators of biosphere ships, cosmic nutrition experts of highest rank, and all the foremost beings everywhere will be instantly revealed to have been physicists, rather than all those previous beings, see? If you are bored now, just wait and see…

  11. Is it just me who thinks Michio Kaku is actually an AI robot who speaks the same content in an identical manner in every talk show or documentary on similar issues?

  12. Moon goes around earth
    Earth goes around sun
    Sun goes around black hole
    What does a black hole go around 🤔🤔🤔🤔🤔🤔

  13. Screw merging with technology. That's probably more type 3 anyway. I want to be one with the universe. Don't stop at Galaxies.

  14. Mr. Kaku – The future of humanity can be found in the Bible. Revelation would be a very good place to start reading right now.

  15. I love when Kaku talks about the levels of technological progress. It is very inspiring. I appreciate his optimism with us reaching “1” from “0”. He thinks we will make. We do too! 7FRVK6

  16. Darwinian life , what’s the alternative? “ so sad seeing him getting old “ very funny ! But he still look good . I understand what U mean I say the same thing when I see Noam C . 😀

  17. It's so funny but interesting what a black hole means but it is a very concerned did the black hole that exist in our brain it is more interesting before we know any black holes of any kind we should fix the hole in our brain to better understand what black means and where the whole fits or are we also whole in a black aspect

  18. The theory of everything is us we make theory for every aspect of any question that fulfills our intellect. kinda wen a question is asked we ask for the reason that we are not sure of the answer we already know Indeed do we really need the words of another being to satisfy the concerns that are very convenient for our needs .so I ask do we really need the answer when the question is irelavent to the truth..us humans are never satisfied that is what make us unique and different to other species of other worlds we have the choice to act upon any situation that implies threat to our own excistece but in reality we are the threat of all existence just for the fact that we never have enough ..so I ask what is everything and what is nothing …lol now your thinking huh ..lets not ask let create instead of asking let's answer before any question I believe thinking takes to long reacting to all that presents in an instant is the way to Transcende Galileo Galilee is my mentor and the 1 to start the illuminated not the Illuminati that is just a carton that hides behind the image witch he lies and hides history has been altered but our future is set beyond expectations there are no limits or obstacles only we are obstacles of our own doing

  19. He's right we create Ai but ai have the concept of perfection we are not perfect wut will you think is going to happen wen they find out we destroy and selfish computers have one job destroy virus I can only imagine how they're going to categorize us in there form of computing not thinking. only we have consciousness but we are not cautious around creations that can destroy us. For the mere fact of our way of thinking and unpredictable that is what makes us perfect and faults at the same time an intelligent person would ask an intelligent question a humble person what ask the million-dollar question forget about the million-dollar would ask the question of a lifetime we all suffer we all have happiness at least for 1 minute but do we really have ourselves 2 replenish everything that we created and we worry of what everyone else needs cuz right now I really do not need anything but everyone

  20. I don't agree with Kaku using the analogy of an ant hill when comparing humans to advanced alien civilizations as though that's how they would think of us. An advanced alien civilization would recognize a sentient species like themselves, primitive though we may be in our current stage of development. They would still recognize a species intelligent enough to split the atom and clawing its way to the next level of its development to a type 1. The aliens would probably say to themselves "these humans are not at all unlike our ancestors 100,000 years ago." In fact they could be observing us right now and comparing the rate of our progress to their own. We normally don't think that way about ants, chimpanzees maybe, but not ants.

  21. this ego boosted demented self addicted cunt is the most evil cunt of this demented pit of science ….. today scientists are nothing more than pit full of idiots … and this cunt , he said of perfect capitalism in his last meeting i saw … this means that this idiot doesn't even know what is 2+2 … this cunt should be in a jail … he is a cunt .. proper cunt

  22. lol , more i am listening more i understand how demented this guy is … retard able to speak …. and all of you brainwashed idiots ,,well , yea listen to him … this idiot should be in a jail …

  23. Yes, I'm a physicist and there are no anti-gravitational particles. So what about dark energy, it repels matter accelerating matter at increasing speed, is that not a form of anti-gravitation?

  24. OMG, this sounds like a copy of a copy of a copy. Google seems to be dabbling in sound like it dabbles in paying taxes and as it dabbles in censorship and covert cooperation with the CCP in China, and by virtue treason against the US. Right Google?

  25. Shh yet another super genius. ..he'll should make a movie a million super geniuses and cannot figure out a bloody thing

  26. Colonize desert planets? no thanks-we live on the most pristine planet- the point of everything– become conscious transform you–so you can live here on this gorgeous planet. billions of unintelligent humans one day will change.

  27. NO Big Bang, No Black Holes, No Dark Matter and definitely NO UNICORNS!!! Is this supposed to physics. Or physistories? wait its physitails? His-story? physantasy? You literally got to be kidding me. No for real is this a children's show. UNICORNS!!!(WTF). It is truly sad the mockery the disrespect the flat out lies, that are being tought to our young people. People pay great deals of money for there children to be tought great lies. By grown men in trusted positions. Michio you know the truth, why won't you teach the reality of our Electric Universe. STOP with the pharrytails. I really feel sorry for the parents and students that trust you. Have a truly Electrical Day.

  28. Michio kaku u mental . Here we indian gives physicist the great honor naming sadguru , bk shivani and pandokar sarkar. These all are intelligent but belonged to poor classes that's why our government named babag the physicist . 🤣🤣

    I m named durge maa because i m equal to these personalities . But i will only go for buisness not anything else .

  29. The idiot on audio is to blame not the equipment you can hear it's up to loud and distorting it's over modulating due to the level peaking out from being to high.

  30. So much technological speculation and focus. While technological advancement will be a component of the future (of course), humanity will be much more concerned with meeting the basic needs of people – a growing population in a declining world. A world with a damaged and changing climate and environment, which will yield less food and less freshwater in many regions. A world of diminishing resources and ever greater potential for disastrous conflict over them. And, as is still largely unrecognized; but is critically important, a world that is being manipulated by intervening forces and groups from beyond the world. The future will be unlike the past, and it will be very challenging. In order to understand this and prepare for it, I recommend the extensive materials published by Marshall Vian Summers.

  31. I stopped listening to Michi last month after waching him ridicule millions of eye witnesses saying they are more likely to have seen "Swamp gas refracting light from Venus", as if there are swamps globally and Venus is shining brightly every night. I know what I saw and he can jump off the nearest cliff as far as I'm concerned.

  32. Il futuro e' la telepatia ai tempi attuali in molti la potevano conoscere meglio senza troppa antipatia

  33. There are very few people in the world who can explain a complex concept in a way that can be understood even by a layman. I adore people like Sam Harris, Brian Green for this very reason. I just found Michio Kaku today and became a huge fan.
    Only complaint is, Google could've hired a better interviewer.

  34. Hello MR. Michio kaku how are you? I'm not sure if you remember me. I'm Joshua , ARK MICHAEL , RA, YAHUAH. I need to speak to you as soon as possible.
