I recently learned what it really means when people say space is constantly expanding. At first I thought it just meant more matter is getting created on the outer areas of the universe or something. But it’s moreso space in the spacial sense is expanding between everything, like a balloon being inflated. This opened up a realm of stuff I hadn’t thought about, with my brain struggling to comprehend how there is finite ‘space’ in that sense. Like how does existence itself have a limit to size? For distance as a concept to exist, the space between atoms has to be finite, and doesn’t break down infinitely. But my brain can’t comprehend this, similar to how it can’t comprehend there being nothing before the big bang. It obviously can’t be infinite because there’d be no existsnce as we know it, but how can it be finite and exist at all?
I guess the question is, how is there a limit to the space between atoms?

This is a great question. I’d like to add: our perception of TIME is essentially a perception of this space increasing. There’s no more fundamental change than that.
So when we say there is increasing “space” between, among, and within atoms, we are ALSO saying “time has passed”. AKA space = time.
Now, I wonder whether the physical measurement of an increase in space is real? If everything is increasing, how can we say that something is increasing at all? If the increase is limitless, is time limitless? Is limitless expansion actually possible? If not, does time stop and/or proceed backwards?
Is it actually an expansion, or is it just the passage of TIME that makes our instruments perceive an expansion?
