Thanks for the answers on my previous thread, it made some sense, and if I'll reply if there's further misconception.
My new question is quite connected to the famous Andromeda paradox. So it's stated that the Andromeda is far away and moving towards the galaxy will cause the observer to have the distant future of Andromeda as his present, in his reference frame (of course future compared to what the stationary observer considers present). So my question is, if we consider a third observer, which is also heading towards Andromeda with the same velocity as the previously mentioned one, but is much more close to Andromeda than the other one, will he consider the same event that the previously one mentioned as his present or will it be also the future one, but one that happened before the event that the observer that is more distant considers present. To sum up, what role does distance to the event play in defining what happens relative to an observer, if they are both having the same velocity, but one is much closer to the event?
This is a sub-question of the first one, but is very connected with it. I know Lorentz Ether Theory is not relevant anymore, but I want to know the postulates to understand SR better. So LET basically says that every observer that is at rest with aether is in a position of privilegy, and that his 'view' is correct, his plane of simultaneity is the universal one. But how is this compatible with the first topic of my post? If two observers are mutually at rest, and of course at rest with aether, they still may have different distances to the objects moving, for example, towards them, therefore they won't consider the same events as their present. Of course, I mean this, if distance plays a role in differences what observers with the same velocity that isn't zero relative to an object consider to be their present. So what is then considered to be the priviliged frame or criteria for absolute simultaneity in LET? In a hypotethical scenario, since it's basically abandoned.
I appreciate your answers, cheers.
