Interesting. Thanks for your response.
So, the universe could be a hypersphere and yet still rapidly expanding in 5D because of dark energy? And then that expansion could drive the universe down to a density parameter of 1, and the hypersphere would morph ('pop?') into a flat universe...
Summary: Looking for detail about what the recollapse of a closed universe would entail
As I understand it, in a universe in which the density parameter is greater than 1, a closed universe, everything would eventually recollapse upon itself. My question is: does this recollapse just refer to...
