Not so, says NASA's Dr. Michelle Thaller, who sees the story of star birth, life, and death as an unfinished puzzle. We talk about the angular momentum paradox, the pitfalls of steady-state astronomy, and an integrated future, where gravity is just one force among many that creates the celestial sky. #NASA #Astronomy #Paradigmshift 00:00 Go! 00:03:53 What we know and don't about star formation 00:04:51 How does a gas stick together in space? 00:06:48 What is the role of chemistry and electromagnetism in star accretion? 00:08:46 The atmosphere blows in the (solar) wind 00:10:42 Is gravity an exception to the rule that objects can't do work on themselves? 00:12:11 Why do stars come in two? What happened to our twin? 00:15:09 Cataclysmic changes to the solar system? 00:20:13 Could a partner star have caused all the destruction? 00:23:42 How do we know we're looking at young stars? 00:26:04 How perspectives change over time 00:32:28 How the color of stars changes 00:33:41 Observing star changes on human timescales 00:35:27 What's the intersection between stellar evolution and rogue planets? 00:36:27 What happens to stars that never make it to fusion? 00:37:32 Lightning Round! 00:37:42 Angular Momentum Paradox: Why does the sun have all the mass but the planets have most of the momentum? 00:39:34 Is it significant that the moon is the perfect size to eclipse the sun? 00:41:25 How common is tidal locking?

When not talking to brilliant people or making movies, she spends her time painting and exploring the woods. Michael Shilo also did his PhD at Columbia studying the elastic properties of molecular water. When he's not in the film studio, he's exploring sound in music. They are both freelance professors at various universities. - Blog: http://DemystifySci.com/blog - RSS: https://anchor.fm/s/2be66934/podcast/rss - Donate: https://bit.ly/3wkPqaD - Swag: https://bit.ly/2PXdC2y SOCIAL: - Discord: https://discord.gg/MJzKT8CQub - Facebook: https://www.facebook.com/groups/DemystifySci - Instagram: https://www.instagram.com/DemystifySci/ - Twitter: https://twitter.com/DemystifySci MUSIC: -Shilo Delay: https://g.co/kgs/oty671
