The ordinary atoms that make up the known universe—from us and the air we breathe to the planets and stars—constitute only 5% of all matter and energy in the cosmos. The remaining 95% is made up of a recipe of 25% dark matter and 70% dark energy. Learn from two scientists on the cutting edge of discovery about these mysterious, nonluminous components of our cosmic cocktail. You’ll hear from a recent inductee to the National Academy of Sciences and the astrophysicist now leading a team to measure the expansion rate of the universe from 10 billion years ago.
Featuring: Katherine Freese, Professor, Physics & Karl Gebhardt, Professor, Astronomy
