1.We have heard of simple toy models of the Universe that were studied by Einstein, de Sitter, and Friedman. If our Universe was 100,000 times denser than it actually is, what fate would the toy-model predict, a Big Crunch, Eternal Expansion, or a Big Rip? Why?
2. In the question above, would the universe have a finite size or would it be indefinitely large?
Fate of the universe is discussed.
