I thought the latest information showed that the expension was actually speeding up, and that the universe was likely going to end in the big rip.
The "force" example was a model of one that has been proposed, but is generally seen as incorrect, not what I believe. I was trying to draw a contrast between the notion of what would make sense in a Newtonian view, versus the GR view.I think you've got this kind of garbled. I don't know what you mean by "force" here; GR doesn't describe cosmology in terms of forces. The expansion of space is one way of talking about cosmological expansion, but it's not the only way, and even in non-accelerating cosmologies you can choose to describe the expansion in terms of an expansion of space.
This is incorrect. Modern cosmological models are not compatible with constant acceleration. They pass through phases that are dominated by radiation, matter, and the cosmological constant, and the dynamics of expansion changes as you go through each of these phases.
We are close to being able to do this, but, for economic and other reasons, such a project won't start for several decades. Once started, the project would take a couple of decades to start to get good results. SeeSo provided that experiments are done measuring the change in red shift of the same object, how accurately can we detect the change (How accurate is the measuring capacity of a modern experiment)? If we measure the red shift of a star in 2000, and again in 2010 how much would it have changed(What is the scale of the change)? It seems like the change would be near infinitesimal. We have only been able to take such measurements for ~80 years, and in measuring the change in redshift of something very distant, it would seem that the time between measurements would be too small to gain meaningful results. Does anyone know how this experimental obstacle has been overcome in practice? OR does it simply not exist for some reason I am missing?
Ok, I'll leave that discussion at that point. I have read good analogies which prove my idea is not correct, so please negate above.What if space is absolute and just time is relative?
