Who falls for this bullshit?
you can't go faster than the speed of light

Duh, it’s called lightspeed x2 idiot

It would be, but it would be difficult to see what is going on because the light would still be travelling at c with respect to the medium. So you would probably pass the other person before you actually saw yourself pass them, like how a hypersonic plane passes you before you hear it.

Relative to an observer in the middle, yes. But if you are one of the objects, the other will appear to be approaching you at sub-light speeds. That's how it works.

No. That's the whole point of relativity - time-space continuum begins to distort because nothing is faster than light. It's the result.

>2x the speed of light? Less? Why?
No. If i am riding on photon A approaching photon B, I will see that it is moving towards me at the speed of light.
This is where time dilation comes from. Speed is calculated by distance/time. Space and time apparently rearrange themselves to make it true that light always moves at the speed of light no matter what.

And this ultimately results from the fact that any measurement of space or time you come up with will ultimately depend on the motion of photons in your frame.
