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

Brian Greene

The real question is whether all your pondering and analyses will convince you that life is worth living. That’s what it all comes down to.

Analysis Down Life Pondering Real
Sometimes attaining the deepest familiarity with a question is our best substitute for actually having the answer.

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.

Holy Rather Something Testable Understand
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.

Journey Long Thinking
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.

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,

Relativity challenges your basic intuitions that you’ve built up from everyday experience. It says your experience of time is not what you think it is, that time is malleable. Your experience of space is not what you think it is; it can stretch and shrink.

…things are the way they are in our universe because if they weren’t, we wouldn’t be here to notice.

Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.

Science is the greatest of all adventure stories, one that’s been unfolding for thousands of years as we have sought to understand ourselves and our surroundings.

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.

Ideas Issues Real
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.

In the far, far future, essentially all matter will have returned to energy. But because of the enormous expansion of space, this energy will be spread so thinly that it will hardly ever convert back to even the lightest particles of matter.
