Logical anomallies abound in an infinite world :/
I mean, it pretty much breaks our entire understanding of physics. How would gravity work? And if gravity changes, that would have an effect on...well, nearly everything else.
And on what grounds would it be infinite? Are we just saying "infinite" and asking no questions, or are we following Einstein's folded plane theory? I'll elaborate on that if asked.
And what of the origin of species? And for that matter, how would the world/universe have formed? What about the sun? Would we still have day and night if there was no round surface for the sun to vanish behind? Would there be oceans?
Mind=completely forgeted.
