This was always my view of the state of the universe from childhood onward. The Void of space is infinite, and within that Void our universe could be one of an infinite number of other universes that we will never know about because they are so far outside our ability to observe them. Perhaps there is as as much relative distance between universes in the Void as there is between galaxies in our own universe.

This concept is the only way I've ever been able to accept that our own universe has a measurable size.

I don't think your childhood view holds up with contemporary views. My understanding is that 3 dimensional space, as well as time are properties of our local universe. There is no space outside the big bang and between universes if multiple exist

That's exactly what I have such a hard time wrapping my head around: The concept that there is not even a Void outside of the borders of our own universe, that existence itself doesn't, well, exist. The fact that "space" (as we define it) is finite just feels so wrong, so impossible.

To be frank, I totally agree. I don't think our brains can comprehend what existence would mean without 3 dimensions and time.
