The universe is microwaving itself. A mystery signal discovered in the 1960s led to a Nobel prize.
In this video, Dianna explores one of the most mysterious discoveries in physics - a constant microwave signal that seemed to be coming from everywhere in the universe. It turned out to be light from an unusual process 13.8 billion years ago.
Special thanks to our Sally Ride level patrons: Alejandro Gutierrez, Brian O'Connell, Darkbit, Dave Butler, David Cichowski, Edi, Fabrice Eap, Henning Bitsch, Kenneth Hunter, Margaux Lopez, and Vincent Flores.
