Time is irrelevant . Because time is a consequence of a measure . And the measure of time is based on the physical movement of things . What matters is the physical existence of everything .
So, things can go FTL relative to each other. That's really interesting, considering that if you go up an escalator @ SOL, you don't get to the top any faster regardless if you run or stand still.
Not really. You would say that both of the light rays were moving at c. If one of those light rays was space ship moving at .99c they would measure the speed of the incoming light ray as c. The closing speed seen from the viewpoint of an observer that is stationary relative to the light ray would be 2c, but every observer would agree that the speed of light is c.
So, regardless of the speed of each emitter, as soon as their combined speeds exceed SOL, each object perceives the other as approaching @SOL?

I could swear I read SOL in relation to "speed of light", along with FTL as "faster than light" As defined : But consulting Wiki, I admit SOL does not exist in that context. My apologies and from now on it'll be "c" Should I address FTL as "c+"?
I was thinking of Tachyons (maybe in relation to entanglement). A particle which does not recognize space, somewhat like neutrinos which do not recognize matter. Here is pretty representation of a Tachyon Please Register or Log in to view the hidden image! https://commons.wikimedia.org/wiki/File:Tachyon04s.gif
If there is ever any evidence of a tachyon, then you can worry about what to call it's speed. I assume you mean "neutrinos that do not interact with matter". They do interact with matter by the way, just very rarely.
