What Does General Relativity Tell Us About Causality?

In our paper, what we do is summarize the kind of axiomatics of general relativity by Ellers Piranha and Schild from 1972. So in GR, what they did is a kind of layered structure to tell you how different mathematical structures can be put on space. And that will happen because the universe in this sense is a block. It's just there. It doesn't evolve per se, but it's a big entity of all events. Okay. Well, then you have this set of events, okay, all of the events in the universe,. You can call it a universe.
