Good day. I've been reading and reviewing the posts and linked references on this forum for about 3 weeks now (enjoying the heck out of the exchanges BTW) and have assimilated much of the information (I think). I am trying to understand how it fits together and several questions remain. This one is keeping me from fully grasping what the area commonly referred to as "The Universe" looks like.
Does the area of space which 13.3 BLYs ago was occupied by the surface of last scattering still exist today? I know we are seeing the remnants of it today and that we have receded some 45BLYs while the photons traveled to where we are now. Does the point or points in space from where the photons were emitted 13.3 BLYs ago still exist as a physical place in the current “Universe”? Set aside, if you can, that in either case we will likely never be able to travel to it.
While I’m at it, evidence supportive of Hubble’s Law includes the observed proportional redshifts of objects throughout space as a result of expansion: how does this happen? Is it coincidence that as space expands photons stretch or is there a deeper connection between them? Are photons tethered to space tagging along for the v > c ride? Are they stretched in the wake of space expansion?
Thanks
