“”When I was five years old... where does Space end?””
When I was eleven or twelve (late bloomer, I suppose) I asked my Dad, “If space is continuously expanding, what is it expanding into?”
He looked at me with that same “CO form Chicago” expression, rolled his eyes at my Mom and I don’t think he answered my question either.
As a seventh grader, my speculation was that it was expanding into whipped cream. At my present age of 63 I suspect whipped cream isn’t the answer. But just being able to ask the question reminds me how “big” our Creator is and just that thought is more fun than whipped cream.

Could the answer be that the Universe isn’t expanding ‘into’ anything, it is expanding ‘from’ the start.
