explain relativity to a kid in 3 sentences
- Relativity is a scientific idea that says how things look and work can change based on how fast you're moving or how strong gravity is around you.
- Imagine you're in a spaceship moving really fast and you throw a ball. To you, the ball moves in a straight line, but to someone on Earth, the ball seems to curve because of the speed of your spaceship.
- This idea helps explain things like why time seems to go slower or faster depending on how fast you're moving, and why gravity affects the way things move.
