$ eli5: black hole Here's how to think about it... ★ Giant Star like a huge fire ball in space runs out of fuel 💥 ! Big Explosion called a supernova collapses inward ⬇️ ? Black Hole! so heavy it swallows everything near it 🛁 Bathtub Analogy 🐟 water spins and gets pulled into the drain drain = black hole = black hole ① GRAVITY the invisible pulling force 🌍 🍎 pulled down 🌍 normal gravity VS EXTREME gravity Everything has gravity. Black holes have SO much not even light can escape! ② EVENT HORIZON the point of no return 🧒 safe! 🧒 danger! SAFE ⚠️ no return Cross this invisible line and you can NEVER come back. ③ SINGULARITY squished into a tiny point ☀️ huge star size of a city → squish! 🤏 tiny dot but super heavy Like squishing the Sun into a marble 🔮 — same weight, tiny size! 💡 Fun fact: The nearest black hole is 1,500 light-years away — so we're totally safe! 🎉 eli5.cc
