I have a much easier time imagining how we would understand the big bang, even though we can't do it yet, than I can imagine understanding consciousness.

There was a long history of speculation that in quantum gravity, unlike Einstein's classical theory, it might be possible for the topology of spacetime to change.

There is a difference between knowing what is true and knowing why it is true

We know a lot of things, but what we don't know is a lot more.

I have a tendency, more than most other physicists, to try to figure out everything all at once, before I publish. And even to try to figure out everything in my head, without pencil and paper.

Im actually, for the most part, a complete agnostic politically.

So when you ask me how string theory might be tested, I can tell you what's likely to happen at accelerators or some parts of the theory that are likely to be tested.

As of now, string theorists have no explanation of why there are three large dimensions as well as time, and the other dimensions are microscopic. Proposals about that have been all over the map.

One very important aspect of string theory is definitely testable. That was the prediction of supersymmetry, which emerged from string theory in the early '70s.

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.

My life needs editing.

Life is like this roller coaster you can’t wait to be tall enough and old enough to get on. But when you get on it you realize you’re afraid of roller coasters.

AN ABSOLUTELY VITAL FILM. Exacting, enraging and revelatory. A clear, temperate and devastating account of high level arrogance and incompetence.

I think anti-Semitism is the meal ticket of the organizations that fight it.

We carry in our worlds that flourish, our worlds that have failed.

We are more speedily and fatally corrupted by domestic examples of vice, and particularly when they are impressed on our minds as from authority.

The political spin in Washington is revolting, just revolting. Its a callous political game.

I find nothing wrong with striving for the impossible. But I find alot wrong with giving up

The presence of God is the finest of rewards.
