People have been smart for a long time. Don't get me wrong, it must of been confusing, terrifying, and felt impossible 100k years ago, but they figured stuff out and superstitions that helped people thrive would have been passed down throughout generations. Unfortunately we can't seem to let go of that superstitious mindset, but when you consider how valuable it would have been when we didn't know why things happened it sort of makes sense

Thanks, seems to be the general consensus. I was just unsure if the great distance would exacerbated the effects, as in- if we watched the twin fly into the distance, they might appear to slow down, even though they moving at a constant speed because their clock would be slowing down, so their movement would also appear slower. I'm not really sure if that's how it works, its just interesting to think about

Thanks for the reply. It was just something I was thinking about and unsure of the answer.

Yeah, I get that it takes an extremely long time for the light to reach us, I think I was just curious about the speed effecting the light, but I suppose it's not fast enough, or close enough to the speed of light to warp time enough to be noticeable.
Just a thought experiment I was playing out in my head but didn't have all the pieces to make it work. Thanks
