When I give this talk to a physics audience, I remove the quotes from my ‘Theorem’.
BRIAN GREENESo 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.

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.
BRIAN GREENE -
According 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.

I’ve seen children’s eyes light up when I tell them about black holes and the Big Bang.
BRIAN GREENE -
…things are the way they are in our universe because if they weren’t, we wouldn’t be here to notice.
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.
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 -
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 -
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 -
If someone wants to place the word ‘God’ on those collections of words, it’s OK with me.
BRIAN GREENE -
Our eyes only see the big dimensions, but beyond those there are others that escape detection because they are so small.
BRIAN GREENE -
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.
BRIAN GREENE -
For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.
BRIAN GREENE -
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.
BRIAN GREENE -
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.
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.
