About this episode
Dean Regas discusses the nature of dark matter and dark energy with Dr. Stacy McGaugh, exploring the possibility of alternatives to the current theories.
By some counts as much as 96% of everything in the universe comes from dark matter and dark energy. And, up to now, both are completely invisible. Few in the field question this theory, but could there be alternatives? Dean chats with Professor Stacy McGaugh from the Department of Astronomy at Case Western Reserve University to learn more.
