Rovelli and white holes
So, I watched the following video from Carlos Rovelli:

as it relates to , a relation between two points. In particular, the one point, which can be considered to be unique, actually ends up to be two points, as I kind of understood his talk, that is in some ways a white hole or a black hole turn into each other. So, in some way, you can think of it as two very distinct things which are in some ways really one.
But, I guess, it is more connected to the general problem of the relationship between two points. For example you can consider one very large point and one smaller point, and you might assume that most of what is going on comes from the large point, because it is bigger, which turns out to not always be true. And of course, you might also have a situation where it seems that everything is mostly going in one direction and very little goes back the other way.
Anyway, to encapsulate, thinking about just two things can get quite involved; which is,, I assume, is why physics, so frequently. has a Bob and Alice. some where.
