What causes things to happen at all in the movie?

The same thing that "causes" things to happen in real life. What we define as entropy.

They even explicitly using this term when referring to the time reversal. Its reversing entropy.

Now I know what you're thinking. "If every action is reversible in an inverse way to an action that has already happened, then that means there has to be a start point/end point at which the entropy and the reverse entropy spin out from"

And you're correct. That event is also detailed in the film. The movie is a puzzle. The very name of it gives away some element of it. Its brilliant once you figure out how it works.

The physics and causality of Tenet actually just doesn't make sense if you think about it for more than 5 seconds. Which is why they explicitly tell you to not think about it.

No, they make sense, but in a sci fi loosey goosey way like most sci fi movies. They tell you not to think about it because, if you aren't already familiar with the study of entropy, trying to work out how this works will take your mind directly off of the film and into irrelevancy, because the movie isn't a science textbook.

Its an action drama film that plays with the laws of physics to make for a cool premise. If you can accept in movies that a man can fly you can accept in this movie that they have devices that reverse entropy. Thats it.
