Many books say "this model of the universe is infinite in nature"
Say the Standard Big Bang Model can be infinite in nature if it has hyperbolic/ flat space.
My questions are:
1. how can an infinite universe begin with a finite singularity?
2. a universe with spherical geometry is finite in space but has no edge because it comes back on itself.
(analogy being the spherical Earth with no edge- analogy is dodgy because Earth exists in 3-D space where as we shouldn't view our universe as existing in a higher dimension)
What does edgeless mean in an infinite universe? I guess my question is- what characterises/ quantify/ qualify an infinite universe?
(eg. is it the maths?)
