Imagine time as a river, sometimes it flows fast, sometimes slow. When you're near something really heavy, like Earth or a black hole, the river slows down. So if you’re floating in space far away from Earth, time moves faster for you than for someone on Earth. That’s why astronauts come back looking slightly younger!
Examples
- If you lived on a planet with twice Earth's gravity, your clock would tick slower than someone living far away in space.
- A GPS satellite experiences time differently from us on Earth, so we have to adjust its clocks every day.
