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!)

comment Why are there no asteroids or meteoroids with relativistic speeds?
Otherwise said, the idea of them being "high speed" in the way you describe is an artifact of the fact they are far away.

comment Why are there no asteroids or meteoroids with relativistic speeds?
My point is that there isn't really "high speed stuff" out there, in that high redshift galaxies aren't really examples of objects moving at relativistic speeds in that comparing our velocities to theres so naively isn't a meaningful statement.

comment Why are there no asteroids or meteoroids with relativistic speeds?
To talk about the relative velocities of objects that aren't near (local) to each other isn't a well defined concept in GR. Distant galaxies don't have velocities greater than $c$, the space between us and them is expanding faster than the speed of light.
