Michio Kaku Quotes

For years, my early work with Roger Penrose seemed to be a disaster for science. It showed that the universe must have begun with a singularity, if Einstein's general theory of relativity is correct. That appeared to indicate that science could not predict how the universe would begin.

Physics grapples with the largest questions the universe presents. 'Where did the totality of reality come from?' 'Did time have a beginning?'

We're going to need a definitive quantum theory of gravity, which is part of a grand unified theory - it's the main missing piece.

We have never observed infinity in nature. Whenever you have infinities in a theory, that's where the theory fails as a description of nature. And if space was born in the Big Bang, yet is infinite now, we are forced to believe that it's instantaneously, infinitely big. It seems absurd.

According to 'M' theory, ours is not the only universe. Instead, 'M' theory predicts that a great many universes were created out of nothing.

To understand the universe in the state that it began in, the so-called Big Bang, we need laws of physics that work better than our current set of rules and procedures, which break down when we try to push them back to the beginning.

I distracted myself from the fear and terrorism by thinking about things like how the universe began and whether time travel is possible.

We'll have four different gravitational wave windows open within the next 20 years, and each of them will see something different. We'll be probing the birth of the universe with this. The so-called 'inflationary era' of the universe. We'll be probing the birth of the fundamental forces and how they came into being.

Every time we get a story that says there was a Big Bang, then people want to know what was before that. And if we find out, what was before that?

I feel that I've often pointed out that there are countless aspects of life and nature that scientists and scientific thinkers cannot explain. Why the universe is accelerating in its expansion and what came before the Big Bang serve as compelling examples. The process of science provides a way to seek answers to those questions.

We can trace things back to the earlier stages of the Big Bang, but we still don't know what banged and why it banged. That's a challenge for 21st-century science.

Sure, nobody will make a fortune if we figure out why the Big Bang happened. But just about everyone would like to know.

I always think of space-time as being the real substance of space, and the galaxies and the stars just like the foam on the ocean.

Wormholes are a gravitational phenomena. Or imaginary gravitational phenomena, as the case may be.

In 50 years - or 20 years, or 200 years - our current epistemic horizon (the Big Bang, roughly) may look as parochial as the horizon Newton had to settle for in his day, but no doubt there will still be good questions whose answers elude us.

My main interest is the problem of the singularity. If we can't understand what happened at the singularity we came out of, then we don't seem to have any understanding of the laws of particle physics. I'd be very happy just to understand the last singularity and leave the other ones to future generations.

It now appears that the way the universe began can indeed be determined, using imaginary time.

You have to say now that space is something. Space can vibrate, space can fluctuate, space can be quantum mechanical, but what the devil is it?

Evolutionary cosmology formulates theories in which a universe is capable of giving rise to and generating future universes out of itself, within black holes or whatever.

Do you realize that if you fall into a black hole, you will see the entire future of the Universe unfold in front of you in a matter of moments and you will emerge into another space-time created by the singularity of the black hole you just fell into?

Because there is a law such as gravity, the universe can and will create itself from nothing.

We are the product of quantum fluctuations in the very early universe.

We need a theory that goes before the Big Bang, and that's String Theory. String Theory says that perhaps two universes collided to create our universe, or maybe our universe is butted from another universe leaving an umbilical cord. Well, that umbilical cord is called a wormhole.

'What was there before the Big Bang?' That's a question that both kids and adults love to pose to anyone who seems sympathetic. After all, if the universe has only been around for roughly 14 billion years, isn't it legitimate to ask what was in existence before the mother-of-all-events cranked up the cosmos?

My present work concerns the problems connected with the theory of elementary particles, the theory of gravitation and cosmology and I shall be glad if I can manage to make some contribution to these important branches of science.
