New posts in Faster Than Light

Wouldn't a negative mass be going faster than $c$ according to our current models of relativity?

Can quantum entanglement be used to coordinate actions at "FTL speeds" without breaking causality or actual faster-than-light communication?

If a photon takes all possible paths, does it travel faster than light?

How do I interpret uncertainty in velocity greater than the speed of light?

Is relativistic statistical mechanics "foundationally" relativistic?

How can I show that the speed of light in vacuum is the same in all reference frames?

Why didn't Lorentz conclude that no object can go faster than light?

So is quantum entanglement actually FTL "communication" or is it mundane pre-determination?

Does gravity sometimes get transmitted faster than the speed of light?

No FTL information implies no FTL travel?
