In this video from the Vatican Observatory Foundation Dr. Brenda Frye (University of Arizona) talks with Br. Guy Consolmagno, S. J. (Director of the Vatican Observatory) about Dark Matter. Dr. Frye connects the idea of Dark Matter all the way back to Johannes Kepler’s theory of orbits in the solar system. Questions arise: do we actually know less now than we once did, and how fast will we progress in our knowledge of the universe?
