The Basics of Relativity: Light Speed, Time Dilation, and the Expanding Universe | ASMR

Tonight we explore the strange reality of Einstein's General Theory of Relativity and what it means for 3 dimensional beings born into a 4 dimensional Universe. It predicts our birth from a singularity in an expanding Universe, the contraction of space at the speed of light, and both black holes and the infinite time dilation at their horizon. It's bizarre that space truly compresses and time actually slows down deep inside gravitational wells and near the speed of light. We literally observe supernovae billions of light years away exploding at half their normal speed. So let's find out about the history and basics of relativity. ▸ Want to leave a tip or connect?: https://linktr.ee/letsfindoutasmr Video credits: Carrol and Ostlie (textbook I used): https://amzn.to/3QtiABm TNG Simulations https://www.tng-project.org/media/ NASA/STSci/ESA Davis and Lineweaver (2003) https://arxiv.org/abs/astro-ph/0310808 Nolan, C.
