Michio Kaku Quotes

M-theory is the unified theory Einstein was hoping to find.

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.

Einstein was searching for String Theory. It not only reconciles General Relativity to Quantum Mechanics, but it reconciles Science and the Bible as well.

I would say in one sentence my goal is to at least be part of the journey to find the unified theory that Einstein himself was really the first to look for.

When you look at the calculation, it's amazing that every time you try to prove or disprove time travel, you've pushed Einstein's theory to the very limits where quantum effects must dominate. That's telling us that you really need a theory of everything to resolve this question. And the only candidate is string theory.

It's an exaggeration to say that I came up with M-theory.

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.

Quantum Mechanics and General Relativity are both accepted as scientific fact even though they're mutually exclusive. Albert Einstein spent the second half of his life searching for a unifying truth that would reconcile the two.

Scientifically speaking, a butterfly is at least as mysterious as a superstring. When something ceases to be mysterious it ceases to be of absorbing interest to scientists. Almost all things scientists think and dream about are mysterious.

To become a theoretical physicist ... you need to have a passionate love affair with the universe.

I like to think that Einstein would look at string theory’s journey and smile, enjoying the theory’s remarkable geometrical features while feeling kinship with fellow travelers on the long and winding road toward unification.

There are a lot of good things about string theory, and it's great that some people want to work on it.

The most important single thing about string theory is that it's a highly mathematical theory, and the mathematics holds together in a very tight and consistent way. It contains in its basic structure both quantum mechanics and the theory of gravity. That's big news.

I'd say many features of string theory don't mesh with what we observe in everyday life.

String theory's biggest prediction is that gravity exists. That's good. That's a lot more than preceding theories could do.

The universe is a symphony of strings, and the mind of God that Einstein eloquently wrote about for thirty years would be cosmic music resonating through eleven-dimensional hyper space.

String theory has had a long and wonderful history. It originated as a technique to try to understand the strong force. It was a calculational mechanism, a way of approaching a mathematical problem that was too difficult, and it was a promising way, but it was only a technique. It was a mathematical technique rather than a theory in itself.

The central idea of string theory is quite straightforward. If you examine any piece of matter ever more finely, at first you'll find molecules, atoms, sub-atomic particles. Probe the smaller particles, you'll find something else, a tiny vibrating filament of energy, a little tiny vibrating string.

I do feel strongly that string theory is our best hope for making progress at unifying gravity and quantum mechanics.

When I was in high school, I was really into string theory and superstring theory and read 'Scientific American.' It's fascinating.

In the book, I make the point that here we have string theory and here we have twistor theory and we don't know if either one of them is the right approach to nature.

There was a long history of speculation that in quantum gravity, unlike Einstein's classical theory, it might be possible for the topology of spacetime to change.

I wouldn't have thought that a wrong theory should lead us to understand better the ordinary quantum field theories or to have new insights about the quantum states of black holes.

One very important aspect of string theory is definitely testable. That was the prediction of supersymmetry, which emerged from string theory in the early '70s.

It's indeed surprising that replacing the elementary particle with a string leads to such a big change in things. I'm tempted to say that it has to do with the fuzziness it introduces.
