Quick plunge in sunlight caused Snowball Earths; remnants of globular cluster found; loop quantum cosmology breaks our brains
Manage episode 268538565 series 2560695
Join us today as we go back in time and examine what caused Earth to become a snowball… more than once. We also take a look at a dismembered globular cluster found at the edge of the Milky Way. And finally, Dr. Pamela gets to explain loop quantum cosmology. Wish her luck!
