Theoretically space is infinite, as it is the ultimate container. So how does it expand? For example if you keep adding objects to a room the room isn’t gonna expand, you’re gonna run out of space. So how does space expand if the cause of it is apparently dark matter being created?
Your own pilot analogy is making the concept of expansion concrete - reifying it.
I don’t see any way to escape the conclusion that space is expanding.
what…?
