And this, of course, is not possible, because if there are these myriad connections, you cannot take into account all of them - especially den in a theoretical model.

And then in a second approximation, i will take into account more inter connections, therefore my theory will be more accurate. We don't know which catastrophe will happen exactly when and where. But qualitatively, we can predict the things
