Tachyons. But anything moving faster than light wouldn't interact in typical ways with matter because the fundamental forces utilize mediator particles that travel at c or slower. We might notice their indirect effects via e.g. curvature of spacetime or other interesting things, but we don't really have a direct way of measuring them.
We don't even know if tachyons even exist and they would violate the laws of physics. This argument is flawed in the beginning because it assumes that going faster than light is possible which we know to not be true. If the OP wants to make this argument then they'll have to prove that FTL travel is possible.
But isn't quantum entanglement cheating by utilizing the multiverse and therefore not moving e.g. a particle faster than c between the two quantum entangled entities to produce the resultant "spooky action at a distance"? I'm not a physicist, theoretical or otherwise, so I am not really qualified to answer any of these questions.
@silvermyth for one... I want my selfie drawring with my cleo (cat)!! On side note... at the quantum level, distance doesn't matter the same way.. in fact it doesn't exist. This is why quantum entanglement works
Two kinds of comments. Both amazing.
