Okay, I'm really speaking out of my league here, but didn't Godel's
Incompleteness Theorem assert something to the effect that no system of 
human thought could ever be both complete and without self-contradiction?
If this is the case, then I suspect that we will at least continue 
refining our scientific theories for as long as we exist.
