What happens if C is faster than the speed of light?

[BrettJimison]

Imagine if we lived on a two dimensional plane, and we had NO understanding whatsoever of a height dimension.
With that in mind:
What if a 3 Dimensional being put a ring (vertically) through our two dimensional plane? We would have NO way of knowing that it was actually a ring. Instead, we would see two separate "dots or lines" from each side if the ring that appear on our plane. To us as 2 dimensional beings, we would see two separate dots that would seem to have no connection BUT if we were to "move" one of the dots, the other one would move with it instantaneously! When is reality we may be moving the ring sideways, it would appear to us as two dimensional beings that the second dot (other side of the ring) was moving instantaneously even though on another dimension they are part of the same thing. We may describe what was happening as "information" moving faster than the speed of light, when in reality, the two dots are part of the same thing (the ring) just in a higher dimension.
Maybe nothing is faster than the speed of light and the transfer of information between to entangled atoms, is really an illusion, when they may actually be part of the same thing in a higher dimension?
Just a way I like to describe it to people who may be unfamiliar with QM.

If you push one part of a ring, the other part does not begin to move within faster-than-light time. This is a common misconception about solid objects. The movement will propagate with the speed of sound. In everyday objects, this is so quickly that you do not notice the delay, but it is there.

Apart from that, your ring would probably ruin the complete 2-dimensional world by making it 3-dimensional.

If you start from the assumption that spacetime is symmetric in certain sensible ways (in particular, symmetry between different frames of reference), then you get either special relativity or Galilean relativity. In SR, there is some invariant speed, which we call c.

If we assume special relativity, then via the lorentz transform, the relative speed between any two objects has a maximum constant value. This value also happens to be the speed of light.

If you measure something faster then the maximum (ie c) then the geometry breaks down, special relativity breaks down, and so does much of physics for the past century.

Your right, hadn't thought of that in terms of this issue. In that case Relativity would still be violated. Good point.
Unless matter (and light) could propagate faster in another dimension that has a different set of laws...obviously that's just philosophical. Good point though!
