To describe "what can and will happen" requires its own assumptions and therefore model. If you can't see a model you are not digging deep enough. Though I understand your point of view. Some think that the fundamental physics can end i.e., a unified theory of everything is possible. It is more likely that it is turtles all the way down i.e, we can always observe phenomena that contradict predictions of current theories (reveal assumptions that are not valid for the phenomenon).
