So like, how does Lemmy work?

When I click on a post, let’s say Lemmy.World, that server sends me the page over the Internet. I get that part. But how does it do comments? Does it tell my phone to go ask lemm.ee and blahaj servers, etc, and fetch the comments?

And why does a post on lemmy.world have have a blahaj URL when I look at it? Is my server making a copy?

    The size of all involved instances grows since they all store a copy.

    if Lemmy1 and Lemmy3 aren’t subscribed to each other, but they both comment on a thread on Lemmy2, will they see each other’s comments?

    Yes, when lemmy2 receives a comment from an outside instance it will then send that comment to all subscribed instances.
