is there a single point in the universe that is at rest relative to all other points?

Answer 1

I doubt it.
How could someone prove it to be?

Answer 2

Yes, every point in the universe is at rest. That's what Einstein's Theory of Relativity is all about. When making calculations concerning relativity, you are allowed to consider any object at rest and proceed from there.

If you're asking there's a "center of the universe" from which everything emanates, no one has found it yet.

Answer 3

Yes.

Any point can be at rest relative to the rest of the universe.

Is there any point that is not in motion? Probably not. But you can choose any point and track the movement of everything else around it. That is the joy of relativity!

Answer 4

Well, because the universe is expanding, the answer is no. The statement that "the universe is expanding" means that to any point in the universe, all other points seem to be moving away from it with a speed depending upon the distance from that point. Now, if there are two objects with an attractive force between them pulling them together, this force can overcome the expansion of the universe and so those two points wouldn't be moving away from each other (this is why your body isn't pulled apart by the expansion of the universe; it's also why planets, stars, galaxies and even groups of galaxies can manage to stay together). But in general, this won't be true for any two points (for instance, there is a force of gravity between me and a star a billion light years away pulling us together, but this force is nowhere near strong enough to overcome the expansion of the universe).

Of course, there is a kind of special frame of reference from which to observe the universe, and that is the frame of reference of the cosmic microwave background radiation (CMB generally). The CMB is radiation left over from the early development of the universe, and this radiation pervades all space. One can measure how this radiation changes with direction and use the principle of redshift in light to give our "speed" with respect to the CMB. It turns out, as might be expected given that the Earth spins on its axis, orbits the Sun, which in turn orbits the center of the galaxy, which orbits around the center of the Local Group cluster of galaxies, that we are indeed moving with respect to the CMB. Indeed, even with all these effects taken out, we (and several other galaxies and galaxy clusters we can see) are moving towards some agglomeration of matter (with a mass of many thousand large galaxies) in the direction of the constellation Centaurus. The object causing this effect has been termed the "Great Attractor". Of course, the Great Attractor itself may be moving with respect to the CMB. But the CMB still gives a special frame of reference.

Answer 5

The special theory of relativity shows that there is no such thing as ab solute space or absolute motion. These have meaning only in reference to other things. So any point could be the "at rest" point in the universe, but we have no way of finding it.

Answer 6

In theory if such a point existed, time would have to be standing still - otherwise it couldn't be at rest relative to all other points.

Answer 7

No. The answer is absolutely, 100% NO. I guarentee it. It is one of the physical laws of the universe. There is no center of the universe. It does not exist.

Answer 8

Yes. Me at 4 am in the morning.

Answer 9

This sounds like a topology question. I guess the answer would have to be yes.

Answer 10

No. At least not that we know of.
