How do the Lorentz equations behave at the cosmic horizon of expansion? How would the equations behave as an object passes that horizon and starts to move away from us above c? Would it appear to freeze in place? Slowly fade? Blink out instantly? Has it ever been observed?

>cosmic horizon of expansion
What exactly are you referring to here? Everywhere is expanding at the same rate

Are you serious?... Well, the rate is the same, but things farther apart move away faster in a linear relationship based on how far away it is. It's the hubble equation. There is a horizon where things are moving away from us faster than c.

Right ok, I thought you were thinking there was some horizon out in space where the universe is expanding from or something
