Black Hole
A place in the sky where the door only opens one way.
§ A first look
§ Depths
Six ways into the same idea — from bedtime story to chalkboard. No order required.

Told like a bedtime story.
For a curious 10-year-old. No jargon. Just a picture in your head.
Okay, throw a ball up. It comes down. Throw it harder — still comes down, you bully. To leave Earth forever you'd need to chuck it at about 11 km per second, which is roughly 'professional cricket bowler, but the ball is on fire and angry.' A black hole is a place in space where even that isn't enough. Not for a ball, not for a rocket, not even for light — which is the fastest thing the universe sells. Once anything crosses the edge, it can't come back. Your ball, your spaceship, your phone, your ex's apology text. All one-way. It is not a hole in the ground. It is a door in the sky, and the door only opens inward.
§ Strange but true
- 01Time slows near one. Watch a friend fall in and they appear to freeze at the edge — forever.
- 02Falling in isn't the scary part. Long before you arrive, tidal forces stretch you into a noodle. Physicists call it spaghettification.
- 03Some black holes evaporate. Hawking showed small ones leak energy and eventually pop out of existence.
