You should never be surprised by or feel the need to explain why any physical system is in a high entropy state.
Brian Greene

I've had various experiences where I've been called by Hollywood studios to look at a script or comment on various scientific ideas that they're trying to inject into a story.
Brian Greene
Image
Before the discovery of quantum mechanics, the framework of physics was this: If you tell me how things are now, I can then use the laws of physics to calculate, and hence predict, how things will be later.
Brian Greene
Image
There may be many Big Bangs that happened at various and far-flung locations, each creating its own swelling, spatial expanse, each creating a universe - our universe being the result of only one of those Big Bangs.

Intelligence is the ability to take in information from the world and to find patterns in that information that allow you to organize your perceptions and understand the external world.
Brian Greene

Sometimes attaining the deepest familiarity with a question is our best substitute for actually having the answer.
Brian Greene

Experimental evidence is the final arbiter of right and wrong.

Oftentimes, if you're talking to a seasoned interviewer who asks you a question, they may do a follow-up if they didn't quite get it. It's rare that they'll do a third or fourth or fifth or sixth follow-up, because there's an implicit, agreed-upon decorum that they move on. Kids don't necessarily move on if they don't get it.

I can assure you that no string theorist would be interested in working on string theory if it were somehow permanently beyond testability. That would no longer be doing science.

The fact that I don't have any particular need for religion doesn't mean that I have a need to cast religion aside the way some of my colleagues do.

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

Gravity is matter’s sugar daddy.

Physicists are more like avant-garde composers, willing to bend traditional rules... Mathematicians are more like classical composers.
Brian Greene
Image
Einstein's theory of relativity does a fantastic job for explaining big things. Quantum mechanics is fantastic for the other end of the spectrum - for small things.
Brian Greene
Image
Far from being accidental details, the properties of nature's basic building blocks are deeply entwined with the fabric of space and time.
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.

Our eyes only see the big dimensions, but beyond those there are others that escape detection because they are so small.
Brian Greene
Image
Many different planets are many different distances from their host star we find ourselves at this distance because if we were closer or farther away, the temperature would be hotter or colder, eliminating liquid water, an essential ingredient for our survival.

In essence, we string theorists have been trying to work out the score of the universe, the harmonies of the universe, the mathematical vibrations that the strings would play. So musical metaphors have been with us in science since the beginning.

I enjoy reading blogs, but am not interested in having my spurious thoughts out there.
