Assessing existence while failing to embrace the insights of modern physics would be like wrestling in the dark with an unknown opponent.
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.

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 -
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 -
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 -
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 -
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 -
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 -
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 -
Gravity is matter’s sugar daddy.
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 -
But if you think about a practical implication of enriching your life and giving you a sense of being part of a larger cosmos and possibly being able to use this [gravitational waves] as a tool in the future.
BRIAN GREENE -
I enjoy reading blogs, but am not interested in having my spurious thoughts out there.
BRIAN GREENE -
Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.
BRIAN GREENE -
Energy is the ultimate convertable currency.
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 -
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.
