589 - How does the concept of time change in space?

Imagine time as a flexible rubber band. On Earth, it moves at the same speed for everyone. But in space, it's different. Because of how fast you're moving and how strong the gravity is, time can move faster or slower compared to Earth.

Here are some cool effects:

1. Time dilation: If you travel really fast in space (close to the speed of light), time will go slower for you compared to people on Earth. It's like time is stretching that rubber band.
2. Gravitational time dilation: If you're near a really heavy object with strong gravity (like a black hole), time will go slower for you compared to people far away from it. It's like time is getting squished by the heavy object's gravity.

For example, if you traveled to a black hole and spent one year there, when you came back to Earth, you might have aged one year, but your friends on Earth would have aged several years. Isn't that mind-blowing?

So, time in space can be affected by how fast you're moving and how strong the gravity is around you.
