Known as "Odd Radio Circles", or ORCs, these colossal structures are a million light-years wide and are changing everything we thought we knew about the cosmos. In this video, we’re delving into the leading theories to explain where these giant rings came from. ▀▀▀▀▀▀ 0:00 WTF? 1:44 The EMU Project 4:32 Discovery 6:41 The First ORC 7:44 What Are ORCs? 10:41 Hypothesis 1: Cataclysmic Event 11:42 Hypothesis 2: Jets 12:48 Hypothesis 3: Starburst Termination Shock 14:03 More Circles 17:24 Cloverleaf ORC 20:03 Hypothesis 4: Galaxy Collision 21:16 The Search Continues ▀▀▀▀▀▀ To stay on top of space news, sign up to the Astrum newsletter: https://astrumspace.kit.com Astrum Displate Posters: https://displate.com/astrumspace?art=5f04759ac338b Astrum Merch: https://astrum-shop.fourthwall.com/ Join us on the Astrum discord: https://discord.gg/TKw8Hpvtv8 A huge thanks to our Patreons who help make these videos possible.
