Faith just doesn't have anything to do with what I'm doing as a scientist. It's nice if you can believe in God, because then you see more of a purpose in things. Even if you don't, though, it doesn't mean that there's no purpose. It doesn't mean that there's no goodness. I think that there's a virtue in being good in and of itself. I think that one can work with the world we have.

Travel at faster than the speed of light certainly can have dramatic implications that are difficult to understand, such as time travel.

Maybe dark matter is denser than we usually assume, kind of like the Milky Way plane.

I did not set out to explain the extinction of the dinosaurs. I'm a particle physicist, and I was actually thinking about dark matter along with some collaborators.

It's hubris to think that the way we see things is everything there is.

Scientific research involves going beyond the well-trodden and well-tested ideas and theories that form the core of scientific knowledge. During the time scientists are working things out, some results will be right, and others will be wrong. Over time, the right results will emerge.

Science is a combination of theory and experiment and the two together are how you make progress.
