The Cosmic Bathtub Drain?
I realize this is outside your expertise, but I’m sure it’s general enough to be within the scope of your training. I just hope it’s not SO general as to be a waste of your time. If so, perhaps you can forward it to someone with copious free time to fritter away…. 🙂 Essentially, the question is this: How can it be determined that, instead of the universe expanding, it is actually being sucked into a very powerful singularity? It seems to me that if this were true, the galaxies “closer” to the event horizon of such a singularity would be accelerated so that they would be red-shifted relative to the Milky Way. Likewise, we would be accelerated beyond those that are “farther” from such an event than we, and thus they would be red-shifted too. I suppose that this hypothetical singularity would not have a specific position in current 3D space, just as the Big Bang’s hypothetical singularity did not. In fact, the more I think about this Cosmic Bathtub Drain, the more it seems to be just
