The Hubble telescope captured an image 230 million light years away. It was an image of two galaxies colliding 230 million years ago.
If I had a space ship that contained FTL technology and traveled 230 million light years into that direction, my understanding is that it would look completely different from the image that was captured by Hubble.
**I guess my question is… how do we get that image from 230 MILLION years ago only just now? My brain wants to view it as a physical photo that flew over here because I just can’t wrap my head around how an old image could reach us.**
** FYI: I read through [this ELI5 thread on light years](https://www.reddit.com/r/explainlikeimfive/comments/2igdlf/eli5how_light_years_work/) and I still don’t really get it. Maybe I’m just stupid :/
Thinking of it as a photo flying over to us is actually just fine.
Imagine you got a letter with a picture of someone’s wedding. If you were to just instantly appear there the very moment you got the letter… They would not still be pos posing for the photo. Depending on how long it took the message to get to you would determine what going on when you arrive.
