Ep. 751: Vacuum Energy

Astronomy Cast Ep. 751: Vacuum Energy By Fraser Cain & Dr. Pamela Gay Streamed live on Apr 7, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay. Even empty space isn't empty. It's filled with the quantum fluctuations of spacetime itself. Which can be measured with famous experiments like the Casimir Effect. There is a surprising amount of energy in space itself, which has led to some interesting theories about how the future of the Universe might evolve. You can't get something from nothing but sometimes that nothing is something you can get something from. SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.
