I personally have never really liked the theory that there is an edge to the universe where there would imply a place outside the universe where there is absolute void.



For me I think the matter of the universe is expanding but the space or time are not expanding however; matter impacts time and space in which it occupies.



We have mapped many galaxies and we have also mapped a point in the universe where we think the center point of the big bang was. It was determined after the plotted distances of galaxies was mapped.



There are other interesting things that were also observed with these galaxy maps. It appears as though there have been smaller bangs after the initial big bang which has caused galaxies to pass back through the center point of the universe.



If you look at these maps the galaxies appear in circular sections sort of like bubbles where the galaxies appear on the edge of the bubble and nothing in their centers. There is a whole slew of these "bubbles" when you examine the galaxy maps.



My theory is there might be a point when perhaps black holes explode and send their mass back out into the universe in the form of gasses and/or heavy elements which become parts of new galaxies and stars. The explosion of these black holes would push the newly forming galaxies out to the edge and create the bubble like appearance on these galaxy maps.



If this theory is correct, it could mean that the universe is a network of smaller bangs that are continuously repeating as black holes form and explode, but this theory is highly debated but solves the commonly held belief that black holes just "fizzle" themselves out after a while.



Although this theory is still highly controversial it does help explain why there is observable blue shifts to some galaxies. It would also explain why Andromeda and the Milky Way are speeding towards each other.



To really understand this theory all you have to do is purchase a brick of firecrackers and observe it closely as you see how each one as they explode pushes the next one in the chain. The firecracker acts like an exploding black hole pushing the material along the chain. This would also account for why the speed of the expansion seems to be increasing or accelerating. As each explosion occurs the rate of movement increases.



This theory also helps to explain how we get the really heavy elements like uranium. We have not seen stars expel the heavier elements like uranium when they explode however; uranium is found very common on earth. And we know that our sun has too small of mass to generate the pressure required to fuse enough electrons and protons together to form uranium atoms.

:) Hi all. I like this question, but one of you is potentially going to owe the other one of you a drink. I think you're all missing something. That's not a criticism; you all seem like intelligent people, but the answer to your mystery is very simple, and might be a matter of "missing the forest for the trees".



When we venture out into the night and look up into the sky, what we are seeing is NOT the 'universe' —at least not really. Every single star and object in the night sky that we see is located within our own galaxy... and not ONLY within our own galaxy, but within a relatively small section of the spiral arm in which we reside. Our very own galaxy is so immense, that astrophysicists don't even understand half of what there is to understand. What they theorize regarding the center of OUR own galaxy differs, (though currently the 'giant black hole' theory remains popular.) So the redshift and blueshift we see are stars revolving around the center of our very own humble galaxy, some moving towards us, some away, held together by gravity (or maybe dark magic)? (and just in case you may not realize, and I'm sure you do, the 'milky way' is us seeing the flat part of our spiral arm from the inside of our galaxy). Does any of that make sense? -Cheers
