>While our current models seem nearly perfect and therefore nearly complete
Huh? Where did you get this idea? Our physics is clearly nowhere near complete. Quantum Mechanics and General Relativity are at odds, which is why physicists have been looking for a unified theory for ages. Each one only works at certain scales, and not at the other end, so obviously something's wrong with them. The whole "dark matter" thing looks like BS too, and alternate theories like MOND don't require it. There's nothing complete at all about our understanding of physics.
