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 GREENEWhen 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.

I can’t stand clutter. I can’t stand piles of stuff. And whenever I see it, I basically just throw the stuff away.
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 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 -
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 -
That is, you can have nothingness, absolute nothingness for maybe a tiny fraction of a second, if a second can be defined in that arena, but then it falls apart into a something and an anti-something. And that something is then what we call 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 -
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 -
String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner.
BRIAN GREENE -
I like ‘The Simpsons’ quite a lot. I love the irreverent character of the whole show. It’s great.
BRIAN GREENE -
There’s no way that scientists can ever rule out religion, or even have anything significant to say about the abstract idea of a divine creator.
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 -
Our eyes only see the big dimensions, but beyond those there are others that escape detection because they are so small.
BRIAN GREENE -
The idea that there could be other universes out there is really one that stretches the mind in a great way.
BRIAN GREENE -
Science is the process that takes us from confusion to understanding.
