For decades, physicists were certain it was a black hole. They observed its effects and even built a planet-sized telescope just to capture its image. But now, a surprising theory is turning our understanding upside down. What if Sagittarius A* isn't a black hole, but something far stranger? ▀▀▀▀▀▀ 0:00 Sagittarius A* 1:58 Supermassive Black Hole 7:30 Isn't it a Black Hole? 8:29 The Black Hole Problem 10:29 Dark Matter Core 12:31 What is Dark Matter? 15:07 Dark Fermions 18:54 The Rotation Problem 20:48 Event Horizon Telescope (EHT) 23:42 Photon Ring 25:42 More Evidence ▀▀▀▀▀▀ Check out Astrum in several languages: Astrum English: @astrumspace Astrum Spanish: @astrumespanol Astrum Earth: @astrumearth Become a member of this channel and get benefits: @astrumbrasil Music: Ridges by Harbours & Oceans, Sonar by Hanna Lindgren, Satellites by Ebb & Flod, Beginner's Mind by Hanna Lindgren, Slipping and Fields by Shuta Yasukochi, Unvaried by Elin Piel, Forest of Eternity by Polar Nights, Black Tide by Lennon Hutton and Marek Poledna By Epidemic Sound ▀▀▀▀▀▀ References: “Imaging Fermionic Dark Matter Cores”, via oup “Stars Orbiting a Dark Matter Compact Object”, via oup “Discovery of Sgr A*”, via arxiv “Astronomers Reveal First Image of the Black Hole at the Heart of Our Galaxy”, via event horizon telescope “Fast Moving Stars in S2 Orbit”, via iop “The Nobel Prize in Physics 2020”, via Nobel Prize “Stellar Orbits Around Central Black Hole”, via arxiv “Elementary Fermions”, via nih “Keplerian Decline in the Milky Way Rotation Curve”, via arxiv “Collapse of "Dark Matter Cores into Supermassive Black Holes", via arxiv ▀▀▀▀▀▀ Credits: Script - Patricia Ward / Dennis Ariel Script Review - Damaris McColgan / Dennis Ariel Editing - Suhith / Dennis Ariel Audio Editing - James Horsley / Dennis Ariel Research - Shourya Shrivastava Thumbnail Design - Peter Sheppard / Juane Dames Narration - Dennis Ariel Production - Alex McColgan / Raquel Taylor / Dennis Ariel Publisher: Georgina Brenner Production Coordination: Rose Unwin Editing Producer - Poppy Pinnock Head of Astrum - Jess Jordan Creator of Astrum - Alex McColgan Special thanks to: Valentina Crespi Dr. Carlos R.
