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 GREENEQuantum 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.

The idea that there could be other universes out there is really one that stretches the mind in a great way.
BRIAN GREENE -
Sometimes attaining the deepest familiarity with a question is our best substitute for actually having the answer.
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.

String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner.
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 -
Physicists are more like avant-garde composers, willing to bend traditional rules… Mathematicians are more like classical composers.
BRIAN GREENE -
To tell you the truth, I’ve never met anybody who can envision more than three dimensions. There are some who claim they can, and maybe they can; it’s hard to say.
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 -
If string theory is right, the microscopic fabric of our universe is a richly intertwined multidimensional labyrinth within which the strings of the universe endlessly twist and vibrate, rhythmically beating out the laws of the cosmos.
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.
BRIAN GREENE -
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 GREENE -
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 GREENE -
When you drive your car, E = mc2 is at work. As the engine burns gasoline to produce energy in the form of motion, it does so by converting some of the gasoline’s mass into energy, in accord with Einstein’s formula.
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 -
How can a speck of a universe be physically identical to the great expanse we view in the heavens above?
