Quote:On an unrelated note, does anyone else like using programs like space engine and try to simulate their own "deep field"? I have way too much fun doing things like that. Image below was taken in Space engine: What the local group would look like from UDF 423 (if you were to magically be transported to it's position in the HUDF and wait 10 billion years), a 10 billion light year distant galaxy captured in the Hubble Ultra-Deep Field. Centre is the Milky Way and the Magellanic clouds, to the right is Andromeda and the Triangulum galaxy. Zoom is similar to the ultra deep field (around 3 arcminutes).I like to use Space Engine, especially for its nebula effects and stellar models.
Your 'Deep Field' simulation is interesting - I didn't realise Space Engine simulated red-shift 'z' effects.
On the other hand Space Engine doesn't simulate expansion, as far as I know. If we were able to see the Local Group 13 billion years ago, it would be a lot smaller and closer together, and if we travelled to see the Local Group from a light-travel-time distance of 13 billion years into the future, we would need to travel to a galaxy which is currently much closer than that. Expansion is weird.
