Hope nobody finds these couple of questions obnoxious.
As the expansion of space-time carries apart the galaxies and the stars which make them up, does it also increase the separation of the planets within the planetary systems of those stars? Furthermore, does it also carry apart all the atoms that make up those planets?
If I were standing on a planet near the edge of the "observable universe" as it would be determined from someone on earth, would Earth then appear to me to be at the edge of my observable universe? And would this be the same regardless of where I was in the universe?
Apart from the phenomenon of red shift, is there any other observable or measurable effect of the expansion of the universe?
