String 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.

Brian Greene

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

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.

About Big General Place String Universe
How can a speck of a universe be physically identical to the great expanse we view in the heavens above?

Heaven Specks Views
But 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.

Holy Rather Something Testable Understand
Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent.

Dark Opponent Physical Wrestling
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.

Ideas Issues Real
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.

A watch worn by a particle of light would not tick at all. Light realizes the dreams of Ponce de Leon and the cosmetics industry: it doesn’t age.

Age Dream Light
Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.

Cosmos Eternity Instead Quieter
Sometimes attaining the deepest familiarity with a question is our best substitute for actually having the answer.

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

If someone wants to place the word ‘God’ on those collections of words, it’s OK with me.

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.

Physicists are more like avant-garde composers, willing to bend traditional rules… Mathematicians are more like classical composers.

Our eyes only see the big dimensions, but beyond those there are others that escape detection because they are so small.

I love it when real science finds a home in a fictional setting, where you take some real core idea of science and weave it through a fictional narrative in order to bring it to life, the way stories can. That’s my favorite thing.
