Is time not absolute?

Time is not the same for everyone, it can stretch or squish, depending on how you're moving.

Imagine you and your friend are both playing with toy cars on a track. You're sitting still, watching the cars zoom by. Your friend is riding a super-fast bike next to the track. From your point of view, time feels normal, like it always does. But from your friend's point of view, things might seem a little funny, maybe the cars are moving slower than they should be.

This happens because when you move really fast, time slows down just a tiny bit for you compared to someone who’s not moving as much. It's like having a special watch that ticks just a little slower when you're zooming around, and your friend has a regular watch that ticks normally.

What does this mean?

  • If you're sitting still, time feels normal.
  • If you're moving really fast, time feels slower to you than it does for someone who's not moving as much.

So time isn’t the same for everyone, it’s relative, just like your toy car track! Time is not the same for everyone, it can stretch or squish, depending on how you're moving.
