Whoa, modern physics is never incorrect? Any science that claims to be perfect is inherently flawed because our current state of science and knowledge certainly isn't complete in any area. We may think we have a pretty good understanding of things but there is absolutely no way we've got it nailed with a flawless understanding. It's not possible.
The only thing we can say for certain is that we don't know what we don't know.
And 50 or 100 years from now someone will look back on what we think we know right now and laugh at how silly and naive we were. And in 1000 years, what we know right now will be a joke if anyone even remembers it.
