>I'm always a bit skeptical about physics because whatever models we find and celebrate now will have to be adjusted at some point in the future...

The physics we have at any given time is tested through experimentation, and has proven effective and accurate to some degree. Within those parameters it's verified.

So skepticism of current physics makes sense to a point, we know it's not complete, but we also know that in a massive range of many complex and sophisticated tests it turns out to be precisely accurate. That's got to count for something.

Testability is a strength not a weakness, it means we know for sure what the limits of our understanding are. Outside the domain of science we have no such heuristic, so we have no idea whether or to what extent anything we think up bears any relation to reality whatsoever.
