If space is expanding infinitely, then sections are contracting infinitely? How do you know this? There is not a single person that has ever lived that knows what is at the end of space/the universe.

Ever heard of logical deduction? Where an object infinitely (and for that matter, acceleratively) expands, it is logically necessary that its “semantic contents” - i.e., the inhabitants on all scales - infinitely contract with respect to the global object. This is standard topology.
This is the essence of a “clopen set” (a set which is concurrently open and closed):
