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
From your perspective…Yes. From the distant object/incident’s perspective…Yes. From somewhere in between…No.
Based on the distance and amount of time it’s takes to travel that distance …. No.
An easier way to imagine it…. Sound travels slower than the speed of light. Imagine The sound of thunder versus the lightning bolt. You see the lightning but hear the sound later. Did they happen when you saw it, or only when you heard it?
