relatively faster than the speed of light ????

If the cosmos is expanding, (which according to measurement in the red-shift it is.) and the more distant the object the faster it is moving away from us, then what happened to the cosmic speed limit ? Surely if there were three galaxies that were aligned and the two outermost were equidistant from the central one, if the two outer galaxies were moving away from the central one at three quarters of the speed of light wouldn't that mean that the outermost galaxies would be moving away from each other at one and a half times the speed of light?

@Curiosity killed ,
There is a difference between "expansion" and "relative velocity". The Universe is expanding, but the expansion occurs from every point in space, not from a particular point. So things are not moving apart due to velocity.

Special Relativity (light speed limits) only apply to velocities.

@rosborne979,
Exactly. The space itself is expanding.
