comment What is the cause of Special Relativity
Physics isn't concerned with "why", only "how!" How these effects take place is due to special relativity, the lorentz invariant universe!

comment In a universe that is expanding at a constant rate, do objects that are attracted to each other feel a force opposite to their attraction?
Expansion of space does not manifest itself as a force in the classical sense! Normally we think of a force as $F=ma$, so if expansion is creating a force we would expect to either experience an acceleration, which is not true, or to gain mass, which is also not true. I don't believe that the agreed upon answer in that other question indicated it there was a force manifestation of cosmic expansion.

comment Does GR really allow superluminal movement?
Yes, good thing to add, I will edit my answer to clarify that such "passive" observations are allowed.

comment Do photons make the universe expand?
@Jakobh: Your understanding of the topic isn't quite right, energy is not conserved in our universe's expansion (preposterousuniverse.com/blog/2010/02/22/…). Also, according to standard inflationary paradigm, curvature is not equal to exactly 0 and it is changing with time (very rapidly so early on!)
