The idea that there could be other universes out there is really one that stretches the mind in a great way.

BRIAN GREENEYou should never be surprised by or feel the need to explain why any physical system is in a high entropy state.
BRIAN GREENEThe beauty of string theory is the metaphor kind of really comes very close to the reality.
BRIAN GREENEString theory is the most developed theory with the capacity to unite general relativity and quantum mechanics in a consistent manner.
BRIAN GREENEIn 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 GREENEI enjoy reading blogs, but am not interested in having my spurious thoughts out there.
BRIAN GREENEA 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 GREENEWe’re on this planet for the briefest of moments in cosmic terms, and I want to spend that time thinking about what I consider the deepest questions.
BRIAN GREENEInstead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.
BRIAN GREENEI like to think that Einstein would look at string theory’s journey and smile, enjoying the theory’s remarkable geometrical features while feeling kinship with fellow travelers on the long and winding road toward unification.
BRIAN GREENEAnd 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 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.
BRIAN GREENESometimes attaining the deepest familiarity with a question is our best substitute for actually having the answer.
BRIAN GREENEFree will is the sensation of making a choice. The sensation is real, but the choice seems illusory. Laws of physics determine the future.
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.
BRIAN GREENEI love it when real science finds a home in a fictional setting, where you take some real core idea of science and weave it through a fictional narrative in order to bring it to life, the way stories can. That’s my favorite thing.
