I got this bizarre idea in my mind, after reading SCP-3321
There, as a person gets teleported through a wormhole, ends up at the edge of the Observable Universe, 46 billion light-years away from Earth. After that, he perceives a dense nebula, that gradually changes colour. From yellow to a reddish colour. It is supposedly dense, and looks sort of like this:
According to the article, the dense nebula becomes red, as the expansion of space-time causes a massive redshift, which causes it to turn red. This effect is magnified by the fact that the nebula is extremely near the edge of the universe. The expansion of space-time too, causes the rocket to move away at really high speeds, and sooner or later, the rocket crashes into the edge of the universe, which supposedly isn't described in the article.
Wait a minute. I think I see something. It looks like this red foam just cuts off, and there's something on the other side. It looks kind of like… it looks like… oh my God-
However, this information is not going to be a actual part of the question, as the information above merely suggests where I got this idea from. The article simply poked my curiosity for space.
However, now let us move onto the "hard-sciencish" part...
On Earth, we simply cannot perceive the redshift of objects on a local scale, as space-time here expands ridiculously slowly. It simply cannot be observed on a local scale. It would be like trying to see a rock move. Space-time here is relatively stationary on a local scale.
Only at several million light years away from us, does the space-time expansion picks up pace and causes motion. And even then, we can see the redshift on a astronomical scale, not on a local scale. Galaxies and stuff are really far away and thus redshift faster. Ending up with something like this:
Looks cool, but this thing is happening at many million light-years away, so it is perceivable. This redshift works only on astronomical scales.
Now, let us move onto the actual question:
Let us say, an observer is stationed at 46 billion light-years away from Earth. Note that this observer is not outside the observable universe, it is still inside the observable universe, but just very, very close to the edge of it.
Now, not only are we just a few million light-years away from Earth, but several billion light-years away. This is simply where the expansion of space is theorized to be faster than the speed of light, strong enough to perhaps affect objects not only on astronomical scale, but at the local scale as well.
The question is:
Would this observer perceive the expansion of space-time on a local-scale
