String theory envisions a multiverse in which our universe is one slice of bread in a big cosmic loaf. The other slices would be displaced from ours in some extra dimension of space.
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.

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 -
Quantum Mechanics is different. Its weirdness is evident without comparison. It is harder to train your mind to have quantum mechanical tuition, because quantum mechanics shatters our own personal, individual conception of reality
BRIAN GREENE -
I was holding [my four-year-old daughter] and I said, ‘Sophia, I love you more than anything in the universe.’ And she turned to me and said, ‘Daddy, universe or multiverse?’
BRIAN GREENE -
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,

It’s hard to teach passionately about something that you don’t have a passion for.
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.

Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.
BRIAN GREENE -
String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner.
BRIAN GREENE -
Science is the process that takes us from confusion to understanding.
BRIAN GREENE -
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.
BRIAN GREENE -
The absolute worst thing that you ever can do, in my opinion, in bringing science to the general public, is be condescending or judgmental. It is so opposite to the way science needs to be brought forth.
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.
BRIAN GREENE -
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 -
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.

I’ve seen children’s eyes light up when I tell them about black holes and the Big Bang.
