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 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.

I like ‘The Simpsons’ quite a lot. I love the irreverent character of the whole show. It’s great.
BRIAN GREENE -
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.
BRIAN GREENE -
I’d say many features of string theory don’t mesh with what we observe in everyday life.
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.

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

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.

But if you think about a practical implication of enriching your life and giving you a sense of being part of a larger cosmos and possibly being able to use this [gravitational waves] as a tool in the future.

Evidence in support of general relativity came quickly. Astronomers had long known that Mercury’s orbital motion around the sun deviated slightly from what Newton’s mathematics predicted. In 1915,

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?’
