while you have stopped, I still try to understand it, as for example, wormholes, you have to understand it to know how time travels works, you must first have to know the teleportation, which can be explained through the wormholes
I know that real science often gives us much more crazy things than science fiction might think up (white holes for example, which are basically the opposite of black holes where anything could come out, like unicorns or space whales).
But the truth is that any mathematical model is just that: a model. It doesn't describe reality fully, it just describes a certain phenomenon. Newtonian physics describes movement pretty well and is still used today, but under extreme conditions it doesn't work quite so well (close to the speed of light). Along came Einstein, who brought us a mathematical model that describes movement at the speed of light.
However if you compute the conditions with Einsteins formulas in a black hole you get infinite density. But there is (in all likelyhood) no such thing as infinite (density) in the real world. E.g. Einstein's model might simply be another edge case (like newtonian physics is for the einsteinian model) and we need a new theory all together which describes reality better.
The same goes for quantum physics btw.: Even though quantum theory is the most experimentally substantiated theory in the world quite a few physicists say that we probably need a new theory which might be able to actually explain quantum effects.
What I want to say is: just because the formulas say that two black holes could be connected does not mean that they actually can be connected in the real world.
There is one curious thing however in reality that is a bit time-traveley: There are some people who made quite accurate predicitions of the future (like the children of fatima who predicted events of the first and second world war with some accuracy). So let me make one (private) prediction for myself: on the 15th, 16th or 17th of June 2019 something fatefull will happen to me and to someone I really care about.
