Michio Kaku Quotes

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

Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle.

From a theoretical point of view, it is very hard to imagine how gravity could avoid being quantized.

One of the main successes of string theory is that it has been able to unify the general theory of relativity, which describes gravity, and quantum mechanics.

I came to realise that string theory offers us the best hope of finding a unified theory of all matter and forces.

I get paid to do what I love. If you understand physics, the foundation of the atomic theory and relativity, you understand how the future is going to unfold. You understand what things are not possible. You understand why things work. I get paid to do what I love the most, and that is to work on the Unified Field Theory and to see the future.

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.

The birth of science as we know it arguably began with Isaac Newton's formulation of the laws of gravitation and motion. It is no exaggeration to say that physics was reborn in the early 20th-century with the twin revolutions of quantum mechanics and the theory of relativity.

There are grounds for cautious optimism that we may now be near the end ofthe search for the ultimate laws of nature.

Physics has a history of synthesizing many phenomena into a few theories.

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

I'm a fan of supersymmetry, largely because it seems to be the only route by which gravity can be brought into the scheme. It's probably not even enough, but it's a way forward to get gravity involved. If you have supersymmetry, then there are more of these particles. That would be my favourite outcome.

What the string theorists do is arguably physics. It deals with the physical world. They're attempting to make a consistent theory that explains the interactions we see among particles and gravity as well. That's certainly physics, but it's a kind of physics that is not yet testable.

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

As for the forces, electromagnetism and gravity we experience in everyday life. But the weak and strong forces are beyond our ordinary experience. So in physics, lots of the basic building blocks take 20th- or perhaps 21st-century equipment to explore.

Technically you need the extra dimensions. At first people didn't like them too much, but they've got a big benefit, which is that the ability of string theory to describe all the elementary particles and their forces along with gravity depends on using the extra dimensions.

During my years at the synchrotron laboratory, I had become interested in the theory of quantum electrodynamics and had decided that what I would most like to do after completing my dissertation work was to probe the short-distance behavior of the electromagnetic interaction.

Einstein comes along and says, space and time can warp and curve, that's what gravity is. Now string theory comes along and says, yes, gravity, quantum mechanics, electromagnetism - all together in one package, but only if the universe has more dimensions than the ones that we see.

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.

Physics without mathematics is meaningless.

Physics has the cutest words.

Through the mythology of Einstein, the world blissfully regained the image of knowledge reduced to a formula.

Is the universe 'elegant,' as Brian Greene tells us? Not as far as I can tell, not the usual laws of particle physics, anyway. I think I might find the universal principles of String Theory most elegant - if I only knew what they were.

I've always been fascinated by physics and cosmology. It gets more and more scary the older you get.

What physics tells us is that everything comes down to geometry and the interactions of elementary particles. And things can happen only if these interactions are perfectly balanced.
