This is for the mathematicians among you:

I still balk at the idea of "dark energy" and other exotic forces to push the Universe apart, if this should become well established mainstream astronomy that the rate of expansion of the Universe is indeed increasing.

So here is a suggestion, but I have not a clue whether the math is working: :roll: What if the overall space of the Universe is four dimensional (not in the Einsteinan sense, but strictly geometrical, as a kind of super cube or hyper sphere without an outer edge)?

I believe to remember that in this case Newton's gravity constant would require a different value to hold it all together. But since it is, what it is, it is doing its thing only in our cosmic vicinity where space flattens out to the familiar Euclidian three directions. :wink:

So only when we scale up we get into the fourth dimension and a Universe where the objects roll apart. How is this for a brain teaser? :)

I believe it all comes down to a mathematical model, which would make predictions on changes in the acceleration rate, perhaps even energy flux and a million other things I can't even think about. But math is my weakness. :cry:
