The Debate about Dark Matter: Is the Matter Settled? - Livestream

The observable universe is made of stars and galaxies and gas. However, it is commonly held in the astronomy community that our universe is also made of an invisible substance called dark matter that is five times more common than ordinary matter.  However, dark matter has never been observed, and the evidence for its existence is still circumstantial.  In this talk, physicist Don Lincoln will give insights into the debate within the scientific community.  You will learn about the historical debate, the reasons dark matter is a currently favored theory, and an appreciation for why researchers continue to look into the question.

Speaker: Don Lincoln, Fermilab
