Possible theories are :- the Universe folding back on itself, Somthing beyond our ability to comprehend, Another Universe expending towards us even God. The answers are varied because we have no proof as to what lies beyond that which we know or can understand.
If the Universe was shrinking the galaxies would appear to be moving towards the Earth, and look more blue than they should. This is the opposite to the universe expanding where galaxies would appear to be moving away from the Earth, which we know due to "red shift". Andromeda would be the exception since it's directly moving towards the Milky Way.
The first article proposing the idea now known as Big Bang Cosmology was written by Jesuit priest Georges LeMaitre. Alexander Friedmann had noted, in 1925, that an expanding Universe was a mathematical solution to general relativity, but never stated that (1) our Universe actually WAS expanding or (2) this fact would have observable consequences. LeMaitre proposed "Hubble's" Law two years before Hubble showed it was a reality.
It was observed that the light from all objects in space was redshifted, meaning all objects are moving away from us. Light from objects further away was further redshifted. This would only happen in an expanding universe.
First, we have no information on whether the universe will end, or if it will continue in perpetuity. It's either one or the other - and yet either answer would be astonishing. Second, we have no idea how the end of the universe might come about, or what the conditions at the end time would be, or if the concept of "after the end of the universe" has any meaning at all. One interesting concept is that of an oscillating universe; a Big Bang of expansion, with gravity overcoming everything in the end and pulling every shred of matter back to itself in a "Big Crunch". This could be the prelude to another "big bang". Each universe would be completely new and unaffected by the last.
You would fall
That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.
The universe simply cant expand at 0 acceleration.
Nobody Knows. Even if we travel at the speed of light we still would die before we got to the end of the universe. Everybody says the universe is expanding, but what is it expanding into?
The universe contains space and time. "Outside" the universe, there would be no space or time, and without these, nothing can exist.

The "Big Crunch" idea was that the expansion would eventually stop and the universe would collapse. All evidence today says no way. The "Yo-Yo" says the universe repeatedly expand, collpses and then expands again of a roughly 70 billion year cycle. There is no evidence for this. The "Big Rip" says the universe will simply expand forever, with other galaxies gradually getting so far away that they fade in the distance, and then stars burn out and everything gets cold and dark forever.
That question cannot be answered. We would have to know the magnitude of every star in the universe. The universe is infinite (and expanding). It's impossible to answer your question.
No it does not. It is my basic understanding of this theory that the 'true center' of the universe would be mostly devoid of material.
we would be all screwed
The shape of the Universe is yet being investigated - it is not known for sure what its shape on a large scale is.As for the expansion, our current knowledge is that the Universe is not only expanding, but that the rate of expansion is increasing (it is expanding faster than in the past). It may be reasonable to assume that this trend will continue in the future, but it would also be a little premature to be completely sure.The shape of the Universe is yet being investigated - it is not known for sure what its shape on a large scale is.As for the expansion, our current knowledge is that the Universe is not only expanding, but that the rate of expansion is increasing (it is expanding faster than in the past).

I suppose because the universe is constantly expanding, so you could never pinpoint just one area.
