I’ve heard people talk about how people living on a space station their whole lives would age at different rates to people on Earth but…how?

It seems everyone is coming at the question from a different angle but usually when people talk about aging in space they are talking about relativity.

The way relativity works is that things that are moving faster experience time more slowly. If you take two clocks and send one up in a rocket to spin round earth a few million times when you put both clocks together again the clock that went up in the rocket will actually be delayed by a few seconds.

Similarly, an astronaut travelling at about a hundred +- miles a second round the earth on a space station will age slower.
