“We all need permission to do science, but for reasons that are deeply ingrained …” — Vera Rubin

I try to do my science in a moral way, and, I believe that, ideally, science should be looked upon as something that helps us understand our role in the universe.

I'm Jewish, and so religion, to me, is a kind of moral code and a kind of history.

In my own life, my science and my religion are separate.

The conclusion is inescapable that non-luminous matter exists beyond the optical galaxy.
