The beauty of string theory is the metaphor kind of really comes very close to the reality.
BRIAN GREENETo tell you the truth, I’ve never met anybody who can envision more than three dimensions. There are some who claim they can, and maybe they can; it’s hard to say.

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.

I like ‘The Simpsons’ quite a lot. I love the irreverent character of the whole show. It’s great.
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 -
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.
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.

Writing for the stage is different from writing for a book. You want to write in a way that an actor has material to work with, writing in the first person not the third person, and pulling out the dramatic elements in a bigger way for a stage presentation.

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.

You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.
BRIAN GREENE -
Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.
BRIAN GREENE -
Physicists are more like avant-garde composers, willing to bend traditional rules… Mathematicians are more like classical composers.
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 -
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.
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.
