I vaguely understand how it works but I don’t understand why it works. Basically it has to do with the order that entities fall in, and if they fall in the same order anywhere in the world, you can build something that detects that.

What’s great is that a recent update made ender pearls load the chunk they’re in, so if you fit every part of the machine into the same chunk as the stasis chamber, it works no matter how far away you are. You don’t even need to build a chunk loader
