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 GREENEBut can we really understand that or put rigorous mathematics or testable experiments against that? Not yet. So one of the big holy grail of physics is to understand why there is something rather than nothing.

You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.
BRIAN GREENE -
How can a speck of a universe be physically identical to the great expanse we view in the heavens above?
BRIAN GREENE -
But if you think about a practical implication of enriching your life and giving you a sense of being part of a larger cosmos and possibly being able to use this [gravitational waves] as a tool in the future.
BRIAN GREENE -
We’re on this planet for the briefest of moments in cosmic terms, and I want to spend that time thinking about what I consider the deepest questions.
BRIAN GREENE -
When you drive your car, E = mc2 is at work. As the engine burns gasoline to produce energy in the form of motion, it does so by converting some of the gasoline’s mass into energy, in accord with Einstein’s formula.
BRIAN GREENE -
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 GREENE -
Writing for the stage is different from writing for a book. You want to write in a way that an actor has material to work with, writing in the first person not the third person, and pulling out the dramatic elements in a bigger way for a stage presentation.
BRIAN GREENE -
I believe that through its rational evaluation of truth and indifference to personal belief, science transcends religious and political divisions and so does bind us into a greater, more resilient whole.
BRIAN GREENE -
To tell you the truth, I’ve never met anybody who can envision more than three dimensions. There are some who claim they can, and maybe they can; it’s hard to say.
BRIAN GREENE -
Cosmology is among the oldest subjects to captivate our species. And it’s no wonder. We’re storytellers, and what could be more grand than the story of creation?
BRIAN GREENE -
In quantum mechanics there is A causing B. The equations do not stand outside that usual paradigm of physics. The real issue is that the kinds of things you predict in quantum mechanics are different from the kinds of things you predict using general relativity.
BRIAN GREENE -
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 number of e-mails and letters that I get from choreographers, from sculptors, from composers who are being inspired by science is huge.
BRIAN GREENE -
I was holding [my four-year-old daughter] and I said, ‘Sophia, I love you more than anything in the universe.’ And she turned to me and said, ‘Daddy, universe or multiverse?’
BRIAN GREENE -
The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers.
