JWST Found an Impossible Galaxy at the Edge of the Universe

In this Astrum Supercut, we're heading back to the birth of the universe. With telescopes like JWST, we’re now able to peer back to the beginning of time to witness the very first galaxies ever to form. But the deeper we look, the more we find things we didn't expect. Are our models of the cosmos actually wrong? To those returning and new to the channel: This video is a Supercut of our best early universe videos, plus some new and updated discoveries. We’ve edited this into a new seamless video, remastered in 4K resolution, and re-recorded the older voiceover to match the quality of the recent episodes. ▀▀▀▀▀▀ 0:00 Unscrambling the Universe 2:07 Webb’s Deep Field 5:16 How Old Is the Universe? 12:16 Cosmic Expansion 17:12 The Black Hole Problem 21:14 Breaking the Eddington Limit 27:42 Disproven? 29:25 The Lithium Problem 36:35 Are Our Models Wrong? ▀▀▀▀▀▀ 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.
