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 GREENEString theory envisions a multiverse in which our universe is one slice of bread in a big cosmic loaf. The other slices would be displaced from ours in some extra dimension of space.

…things are the way they are in our universe because if they weren’t, we wouldn’t be here to notice.
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 -
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 -
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 -
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.

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.

Physicists are more like avant-garde composers, willing to bend traditional rules… Mathematicians are more like classical composers.
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 -
The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers.

Energy is the ultimate convertable currency.

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 -
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 -
The idea that there could be other universes out there is really one that stretches the mind in a great way.
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.

When I give this talk to a physics audience, I remove the quotes from my ‘Theorem’.
