About Patrick Weiler Expertise I`d be pleased to answer questions about any aspect of astronomy, particularly those related to cosmology, astrophysics, and planetary sciences. I can also provide reliable information on unique topics like dark energy, dark matter, black holes, etc.,.
Experience Teacher, adult after-hours education at local community college, including frequent "star parties." I have my own telescope system, and continue to stay apace of recent developments and emerging theories in the field.
Education/Credentials BA, liberal arts with emphasis on sciences. BS, computer technology.

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.
