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.
BRIAN GREENETo 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.

Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.
BRIAN GREENE -
If someone wants to place the word ‘God’ on those collections of words, it’s OK with me.
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 -
Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent.
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 -
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 -
String theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner.
BRIAN GREENE -
The strings of string theory are vibrating the particles, vibrating the forces of nature into existence, those vibrations are sort of like musical notes. So string theory, if it’s correct, would be playing out the score of the universe.
BRIAN GREENE -
You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.
BRIAN GREENE -
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.
BRIAN GREENE -
How can a speck of a universe be physically identical to the great expanse we view in the heavens above?
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.

Quantum 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.
