    Three minutes before BB .

    Depth meaning , there is lack of understanding before BB .

    If two light rays approach each other @ SOL, are they closing the gap between them @ 2x SOL?

    If they recede from each other are they widening the gap @ 2x SOL ?

    There was no time before the BB. Time began with the BB.

    Even t - 1 = makes no sense.

    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 .

    Isn't that what I just said?
    BB is the beginning of physical existence and movement and "duration".

    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?

    What do you mean with SOL ?

    What? No. Don't make it complicated; every inertial observer measures the speed of light as c.

    Didn't want to sound too scientific......

    He means Speed Of Light for SOL. He should just write c.

    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+"?

    Since nothing can move faster than light you can call it whatever you want.

    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

    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.

    Where does the mass increase come from , when mass gets closer to the speed of light ?
