Why does the sun rise and set?
Every morning, the sun climbs up over the horizon like it's waking up from sleep. Every evening, it sinks back down like it's going to bed. But here's the twist: the sun isn't actually moving at all. You are.
Earth is a giant spinning ball, rotating once every 24 hours. Right now, as you read this, you're riding on that spin at about 1,000 miles per hour. You don't feel it because everything around you — the air, the ground, your chair — is spinning with you, like passengers on a smooth train.
