I’d say many features of string theory don’t mesh with what we observe in everyday life.
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.

How can a speck of a universe be physically identical to the great expanse we view in the heavens above?
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 -
The idea that there could be other universes out there is really one that stretches the mind in a great way.
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 -
According 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.
BRIAN GREENE -
Relativity challenges your basic intuitions that you’ve built up from everyday experience. It says your experience of time is not what you think it is, that time is malleable. Your experience of space is not what you think it is; it can stretch and shrink.
BRIAN GREENE -
Gravity is matter’s sugar daddy.
BRIAN GREENE -
Sometimes attaining the deepest familiarity with a question is our best substitute for actually having the answer.
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 -
I enjoy reading blogs, but am not interested in having my spurious thoughts out there.
BRIAN GREENE -
We’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 GREENE -
Energy is the ultimate convertable currency.
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 -
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 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.
