Science is the greatest of all adventure stories, one that’s been unfolding for thousands of years as we have sought to understand ourselves and our surroundings.
BRIAN GREENEString 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.

Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.
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 -
I enjoy reading blogs, but am not interested in having my spurious thoughts out there.
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 -
Energy is the ultimate convertable currency.
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 -
I can’t stand clutter. I can’t stand piles of stuff. And whenever I see it, I basically just throw the stuff away.
BRIAN GREENE -
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.
BRIAN GREENE -
The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers.
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 -
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 -
The beauty of string theory is the metaphor kind of really comes very close to the reality.
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 -
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 -
Gravity is matter’s sugar daddy.
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 -
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 -
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 -
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 -
A watch worn by a particle of light would not tick at all. Light realizes the dreams of Ponce de Leon and the cosmetics industry: it doesn’t age.
BRIAN GREENE -
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 -
I’ve seen children’s eyes light up when I tell them about black holes and the Big Bang.
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 -
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 -
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
