ELI5: How is it possible that space is infinite?
gpt
The problem with this question is it has no satisfying answer. You can easily counter with 'How is it possible that it could be finite?"

Neither of these things are truly comprehensible to humans. We're stuck on this tiny little ball of mostly water after all. The less than helpful answer is that space is infinite because it is. Its a fundamental property of the universe.  We can't really comprehend the idea of infinite space, but its still the reality of the situation regardless.
