eli5 Is it correct to think of events happening on the far side of the universe or in a different galaxy as occurring “at the same time”?
In: Physics
Time is relative to the observer. Some say that time isn’t how you perceive it, but rather that everything is happening at once. If you look at a supernova for 1000 light-years away, that explosion isn’t happening now as you watch it. It happened 1000 years ago but you are just now seeing it.
