Rocket Roundup for January 6, 2021: Year in Review
Join us for this week’s Rocket Roundup with host Annie Wilson as we look back at the launches and missions that happened last year, including test flights and first flights, mission launches and discoveries, and all the people in space (and their zero-gravity indicators). Plus space toilets.
Primordial Black Holes, Dark Matter, and… the Multiverse?
Theoretical physicists have found a way to possibly detect primordial black holes which could lead to answers about dark matter and maybe even the existence of a multiverse. Plus the age of the Universe, a wobble in Mars’ axis, and that pesky candidate signal from Proxima Centauri.
