Scientists have argued for decades about how and why the universe is expanding. Now, after careful measurements using multiple methods, the main two don’t add up. What do we do when our measurements of the universe don’t match up with our models? Are all of our theories wrong? ▀▀▀▀▀▀ 0:00 Cosmology Is in Crisis 1:09 Universe Expansion 6:28 The Hubble Constant 9:18 Early Universe 11:41 Dark Energy 13:29 The Values Don’t Add Up 17:37 Is the Universe Spinning? ▀▀▀▀▀▀ Astrum's newsletter has launched!
