Description

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.
