“How stars move tell us that most matter in the universe is dark. When we see stars in the sky, we're only seeing five or 10 percent of the matter that there is in the universe.”

As quoted in Pontifical Science Academy http://www.ewtn.com/library/ISSUES/STELLAR.TXT

“There is one alternative to dark matter, and that is the assumption that Newton's laws don't hold over distances as great as galaxies. But we know that Newton's laws hold over a very large domain. And virtually one hundred percent of the physics and astronomy community believes that there is matter in the universe that does not radiate.”

As quoted in [Astronomer Vera Rubin—The Doyenne of Dark Matter, Discover Magazine, http://discovermagazine.com/2002/jun/breakdialogue] (1 June 2002)

“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.”
