If string theory is right, the microscopic fabric of our universe is a richly intertwined multidimensional labyrinth within which the strings of the universe endlessly twist and vibrate, rhythmically beating out the laws of the cosmos.
BRIAN GREENEWe do not know whether there are extra dimensions or multiverse. Let’s go forward with the possible ideas that come out of the mathematics. It’s hard for us to imagine a universe that would have no time at all.

In the far, far future, essentially all matter will have returned to energy. But because of the enormous expansion of space, this energy will be spread so thinly that it will hardly ever convert back to even the lightest particles of matter.
BRIAN GREENE -
The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers.
BRIAN GREENE -
Free will is the sensation of making a choice. The sensation is real, but the choice seems illusory. Laws of physics determine the future.
BRIAN GREENE -
Quantum Mechanics is different. Its weirdness is evident without comparison. It is harder to train your mind to have quantum mechanical tuition, because quantum mechanics shatters our own personal, individual conception of reality
BRIAN GREENE -
Falsifiability for a theory is great, but a theory can still be respectable even if it is not falsifiable, as long as it is verifiable.
BRIAN GREENE -
The beauty of string theory is the metaphor kind of really comes very close to the reality.
BRIAN GREENE -
I’d say many features of string theory don’t mesh with what we observe in everyday life.
BRIAN GREENE -
The strings of string theory are vibrating the particles, vibrating the forces of nature into existence, those vibrations are sort of like musical notes. So string theory, if it’s correct, would be playing out the score of the universe.
BRIAN GREENE -
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.
BRIAN GREENE -
How can a speck of a universe be physically identical to the great expanse we view in the heavens above?
BRIAN GREENE -
…things are the way they are in our universe because if they weren’t, we wouldn’t be here to notice.
BRIAN GREENE -
You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.
BRIAN GREENE -
Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent.
BRIAN GREENE -
Physicists are more like avant-garde composers, willing to bend traditional rules… Mathematicians are more like classical composers.
BRIAN GREENE -
And putting together the probabilities of quantum mechanics with the certainty of general relativity, that’s been the big challenge and that’s why we have been excited about string theory, as it’s one of the only approaches that can put it together.
