Comment on He's gonna be walking for a little bit
Thedogdrinkscoffee@lemmy.ca 4 weeks agoWhat doesn’t make sense to me is infinite rooms and infinite guests and is full. You ask everyone to move down 10 rooms, why is 1-10 now free? You had infinite guests too, wouldn’t more filled rooms appear?
Or Is infinite only infinite (undefined) on the upper end, but defined on the lower? E.g. 1.

You can define the start of an infinite series, just not the end. (Except as ∞ or -∞). You could also have an infinite set that extends both ways.
0 to ∞ contains an infinite amount of numbers. But so does 11 to ∞.
More filled rooms do not “appear”, the rooms just go on without end. These is no “last” guest who moves into some previously unoccupied room. It’s just… endless. Infinite.
It really only makes sense in abstract. Our minds aren’t built to deal with infinity.

Thanks. My mistake was to view infinite as strething without end in both directions. Today I learned. Thanks.
