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

…things are the way they are in our universe because if they weren’t, we wouldn’t be here to notice.
BRIAN GREENE -
For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.
BRIAN GREENE -
It’s hard to teach passionately about something that you don’t have a passion for.
BRIAN GREENE -
So many galaxies, so many planets out there in the universe circling so many stars… it just feels like there’s a very good chance that there is another Earth-like planet out there that is able to support some kind of life similar to what we’re familiar with.

I’ve seen children’s eyes light up when I tell them about black holes and the Big Bang.
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 boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers.
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 -
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.
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 -
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.
BRIAN GREENE -
We 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.
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 -
I would say in one sentence my goal is to at least be part of the journey to find the unified theory that Einstein himself was really the first to look for.
BRIAN GREENE -
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.
