I suspect the reasoning is less complex.
Humans have senses that have evolved to fit our environment. As Darwin explained. There's no reason that a whole lot of physics occurs outside of our sense organs. We already know some, of course, in the electromagnetic spectrum. And, more recently, gravity waves (though I remain a little sceptical on that one).
The likelihood of physics occurring in a domain we haven't yet accessed is anyone's guess. But I consider it to be high.
It's reasonable to conclude that physics will become ever more inaccessible to a layman, because the models will become ever less intuitive.
I hope I live to see the equivalent of Penzias and Wilson in a whole new domain.
