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

One of the nice things about math and science is it’s obvious, you get the answer or you don’t get the answer.

All the normal matter in the Milky Way disc is denser than the dark matter that surrounds it.

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

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.

Although I was first drawn to math and science by the certainty they promised, today I find the unanswered questions and the unexpected connections at least as attractive.
