Brian Greene Quotes

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.

In many ways, string theory attempts to go beyond Einstein's dream... an all-encompassing description of nature that works at large distances where gravity becomes important as well as small distances where quantum mechanics is important.

Our best theory of describing space at a fundamental level is probably string theory.

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

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

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.

String theory is not the only theory that can accommodate extra dimensions, but it certainly is the one that really demands and requires it.

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.

The beauty of science is to imagine more than we can prove. And string theory gives you a radically different interpretation of the universe.

I work in string theory. This is a branch of physics which assumes that the elementary objects in the universe are not particles but one-dimensional objects, that is, strings.

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.

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

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

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.

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

String theory has the potential to show that all of the wondrous happenings in the universe - from the frantic dance of subatomic quarks to the stately waltz of orbiting binary stars; from the primordial fireball of the big bang to the majestic swirl of heavenly galaxies - are reflections of one, grand physical principle, one master equation.

I just think too many nice things have happened in string theory for it to be all wrong. Humans do not understand it very well, but I just don't believe there is a big cosmic conspiracy that created this incredible thing that has nothing to do with the real world.

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

The quest for a quantum gravity is one of the greatest unsolved problems in all of science.

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

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.

As you say, the way string theory requires all these extra dimensions and this comes from certain consistency requirements about how string should behave and so on.

Every string theory that's been written down says the speed of light is universal. But other ideas about quantum gravity predict the speed of light has actually increased.

We know there must be new physics. For example, we cannot explain what dark matter is.

Space can vibrate, space can fluctuate, space can be quantum mechanical, but what the devil is it? And, you know, everybody has their own idea about what it is, but there's no coherent final consensus on why there is space.
