Theoretically, no.

Theoretically, yes.

It is theoretically impossible for any object to accelerate to the speed of light (and therefore accelerate to a speed higher than the speed of light).

It is theoretically possible for particles or waves to exist that naturally exist at speeds higher than that of light. See tachyons. Such particles could theoretically not slow down to or below the speed of light.

I've only read theories about what would happen if we reached the speed of light, but never if we exceeded it. Maybe it's an absolute limit of speed we haven't discovered yet? Theoretically, we should be able to accelerate for as long as we want, but we also thought the world was flat at one point.

No, that's not true at all and displays an ignorance of basically all science to have ever been done since 1904.

Yeah some stuff in physics has things that happen instantly in non-local effects, but its not quite like a signal, more of an influence in whatever is forming matter. If Ive read my text books right lol.

The Long Answer

I gave you the short answer though I was entirely accurate.

And yet you are contradicted by your own link.

"There are several serious possibilities for real FTL.."

"theoretical physics as we presently understand it seems to leave the door open to the possibility."

I saw something recently on one of the science channels that explained that the speed of light according to Einstein, is actually a speed limit. Even if you are on an object traveling at the speed of light and you turn on a flash light, the light will travel at the same speed though it might seem to be going slower. Now how would that look from a stationary object? Light still travels at the same speed, 186,000 miles/sec, so that's the limit.

That is incorrect. Either you misunderstood the show or they failed terribly at explaining the constancy of c.

Are they still putting that on TV? We had that in primary school books lol.

According to Stephen Hawking, the speed of light is like a cosmic speed limit that no one can surpass. So not in real life as far as we know.

In any case, it seems to be only a possibility that hasn't yet been proved. It certainly seems unlikely humankind will ever be able to achieve such speeds in any case, at least in anything but a particle accelerator.

Superluminal speeds are theoretically impossible in a particle accelerator.
