Well, the universe having a finite amount of space (not just a finite amount of energy/matter) would imply some sort of unbreakable, impassible “edge of the universe”, which seems pretty ridiculous to me. Now in an infinitely large universe, finite energy/matter will continue to expand asymptotically towards 0 energy/matter per unit space. If there is infinite energy/matter, it converges to a finite density (assuming the spacial infinity and energetic infinity are in a linear ration).
No, not necessarily. If, for example, it could be represented in higher dimensions as a hypertorus or a hypersphere, it would be finite in extent yet not have an edge.
I’m not questioning why the universe would be infinite, rather than finite.
Also, most sources I can find strongly hint at there also being an actual infinite number of galaxies, Max Tegmark for example. It’s not a fringe idea certainly. If I find a single authoritative and concise source, I’ll link it. This comes close.
