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

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 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 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 -
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 -
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 -
How can a speck of a universe be physically identical to the great expanse we view in the heavens above?
BRIAN GREENE -
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 -
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 -
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.
BRIAN GREENE -
When I give this talk to a physics audience, I remove the quotes from my ‘Theorem’.
BRIAN GREENE -
Sometimes attaining the deepest familiarity with a question is our best substitute for actually having the answer.
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 -
Quantum mechanics, that big, new, spectacular remarkable idea is that you only predict probabilities, the likelihood of one outcome or another. That’s the new idea.
BRIAN GREENE -
I’d say many features of string theory don’t mesh with what we observe in everyday life.
