You can't see time. We experience time, and do so only on and near earth and our solar system area. That is the only time we know. You look at light coming in HERE, to our rules and time zone, and you assume that light from some unknown time and space operated always in this time?!
We could get a little more complicated, but I try to avoid that where possible.
The fine structure we see in atoms (from anywhere) is also only seen here. It doesn't matter where the atoms are from, they are only seen here.
False. False. False. You do not know how many years are involved for any star in the sky. Not only that, but the light and info from all stars is only seen HERE!!!!
You are using a TIME measure. 8 months. Not only that, but you are talking about an area where we do not even know that time as we know it exists at all. What 'unfolds' in our time as 8 months, may be extremely different out there in unknown time and space.
Einstein merely started off with the belief and assumption that time and laws and light speed were the same everywhere. Then he did math accordingly. That might be better called special fishbowl relativity.
