String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner.
BRIAN GREENEI’d say many features of string theory don’t mesh with what we observe in everyday life.

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 -
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.

How can a speck of a universe be physically identical to the great expanse we view in the heavens above?

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.

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 -
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.

Energy is the ultimate convertable currency.

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,

That is, you can have nothingness, absolute nothingness for maybe a tiny fraction of a second, if a second can be defined in that arena, but then it falls apart into a something and an anti-something. And that something is then what we call the universe.

You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.
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.

Cosmology is among the oldest subjects to captivate our species. And it’s no wonder. We’re storytellers, and what could be more grand than the story of creation?
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.

The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers.
