So many galaxies, so many planets out there in the universe circling so many stars… it just feels like there’s a very good chance that there is another Earth-like planet out there that is able to support some kind of life similar to what we’re familiar with.
BRIAN GREENEAccording to inflation, the more than 100 billion galaxies, sparkling throughout space like heavenly diamonds, are nothing but quantum mechanics writ large across the sky. To me, this realization is one of the greatest wonders of the modern scientific age.

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.

Every moment is as real as every other. Every ‘now,’ when you say, ‘This is the real moment,’ is as real as every other ‘now’ – and therefore all the moments are just out there. Just as every location in space is out there, I think every moment in time is out there, too.

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.

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.

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.

If someone wants to place the word ‘God’ on those collections of words, it’s OK with me.

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

Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent.

The beauty of string theory is the metaphor kind of really comes very close to the reality.

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,

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.
