05: Cosmic Perturbations & Gravitational Waves

In episode 5 of the GEMMA Podcast, GEMMA intern Chance Spencer interviews Ethan Siegel, a theoretical astrophysicist and author for the blog “Starts With A Bang” which is featured in Forbes and Medium. Starting their conversation by unravelling Olbers' Paradox, they discuss the four predictions the Big Bang model implies, Einstein's "biggest blunder", how gravitational waves can let humanity peer past the cosmic microwave background, and how the matter that we interact with everyday is only 4.9% of what makes up the universe.
