What do people think about the idea that time isn’t linear? Like, instead of time just moving forward from past to present to future, all three might actually coexist at the same time, and we only experience it sequentially.

Is there a name for this idea? And is there any scientific theory or philosophical concept related to it, or is it purely hypothetical? (I couldn’t fall asleep)

If aliens were observing Earth from light-years away, they’d be seeing our past because light takes time to travel. And if they moved closer, they’d see more recent events in Earth’s timeline.

But would it ever be possible for them to see Earth’s future instead of its past? Or does physics make that impossible?
