Hypothetically speaking of course, if we were to observe a galaxy billions of light years away on the opposite end of the universe through a wormhole, what would the red shift look like compared to other galaxies in the observable universe? For example, I'll set up a thought experiment. We have two galaxies, galaxy A and galaxy B. Both galaxies are at the same distance away in the the farthest reaches of the observable universe, both have the exact same brightness and both are traveling at the exact same velocity. Galaxy A is on the left, galaxy B is on the right, however in front of galaxy A we have an open wormhole like a looking glass giving us a closer look at that galaxy. What would we see in the red shift? How would the red shift differ between galaxy A and galaxy B?
