Vera Rubin Quotations

No observational problem will not be solved by more data.

Does Sex Matter? Of course it does. But does it matter enough to Matter? That's a different question.

Science progresses best when observations force us to alter our preconceptions.

In a spiral galaxy, the ratio of dark-to-light matter is about a factor of ten. That's probably a good number for the ratio of our ignorance-to-knowledge. We're out of kindergarten, but only in about third grade.

We became astronomers thinking we were studying the universe, and now we learn that we are just studying the 5 or 10 percent that is luminous.

Science is competitive, aggressive, demanding. It is also imaginative, inspiring, uplifting.

We are still groping, as if we are in a black room trying to make a black puzzle.
