I thought I was clear but I guess not. When we are looking at another galaxy it is moving. The far side of that galaxy is 100, 000 years or so older there for where it was 100, 000 years ago. The question makes perfect sense to me and I am sure there is a simple answer.
What kind of question is that? All galaxies are moving (in fact everything is moving relative to us), it doesn't matter where to or where from just that it is. Maybe it is moving so slow that the effect is negligible at best?
no but it does mean that you are seeing a different age of the galaxy from one side to the other. and galaxies are moving as a whole, so you would think that the far side would almost look bent back towards where the galaxy is coming from and the near side would look bent to where it is going...
When I typed blur I was immediately visualizing this to be wrong. Maybe more of an elongation? But I guess that it so slight to not make much difference. I really feel like we actually don't understand the true nature of light, but I guess applies to a whole slue of things in the very tiny world...
This question has been nagging at me: How are we able to get a clear picture of a galaxy if the light from the far side of a galaxy is arriving 100,000 years or so after the light coming from the near side. With a 100,000 year difference the stars that we are seeing in the far side wouldn't even...
