About

Explore the universe like never before with Astrophysics Crash Course! This series breaks down the basics of astrophysics — from gravity and light to stars, black holes, and the expanding universe — turning star stuff into something you can actually get. If you’re curious about space, you’ll get a solid grasp of how the universe works, without all the complicated stuff getting in the way. 🌟🔭🚀
