Nothing really antimatters

April 30, 2021 08:42 - 32 minutes - 30.1 MB

Welcome back, Spherical Cow Moonions! This week we are discussing the topic of antimatter! What is antimatter? How was antimatter first discovered? Why is there such an imbalance between matter and antimatter in the universe? Listen to this episode to find out more! Please see some amendments/additions to our discussion: Around 10:50 - I misspoke here! The weak force only governs beta decay. Alpha decay is essentially caused by a quantum mechanical phenomena called quantum tunneling! Aro...
