Stars. Black holes. THE GAWDANG UNIVERSE. Astrophysicist and cosmologist Dr. Katie Mack (@astrokatie) re-introduces us to this 2017 episode along with some bonus updates on astrophysics, her career, and the book she’s published since we last heard from her. Katie also tells us her most embarrassing moments as a cosmologist, debunks some physicist myths and gives us the nuts + bolts of everything form particle physics to gravitational waves and existential mysteries. Walk away with cocktail party comprehension of everything from the itty-bitty quarks that make you to the neutron stars banging together across the cosmos. More than anything, get perspective about your life on this, our little pale blue dot.Visit Dr. Mack’s website and follow her on Instagram, Twitter, YouTube and TikTokBuy Dr. Mack's new book: The End of Everything (Astrophysically Speaking)More episode sources & linksSmologies (short, classroom-safe) episodesSponsors of OlogiesTranscripts and bleeped episodesBecome a patron of Ologies for as little as a buck a monthOlogiesMerch.com has hats, shirts, masks, totes!Follow @Ologies on Twitter and InstagramFollow @AlieWard on Twitter and InstagramEditing by Steven Ray Morris and Mercedes Maitland of Maitland Audio ProductionsTranscripts by Emily White of The WordaryWebsite by Kelly R.
