@appolose. Stop making up this 'basic scientific tenet' that means a well supported theory can't be proven wrong, it doesn't exist and goes against the very nature of science. Science tries to prove things wrong, a single contradictory observation (as long as we are sure enough that it is a real observation) is enough to sink a scientific theory. For example if we were to create energy without using matter then we would violate the conservation of energy and quite a lot of physics would have to be discarded. It would be discarded.
As such an observation contrary to an established theory changes or destroys the theory, it does not invoke the supernatural.

@Final. The only way I could think of that happening was a violation of logic, which is why I put that condition in my question =P.

See my response to Finalfan.  My example is not one of science having observing one thing then not observing it, but of a different nature all together.  I will be the first to say that theories can be proven wrong, given that they have counter-observations.  My example is not one of counter-observations.

Also, I do not believe that a single observation to the contrary will defeat a theory; see my response to Khuutra on that.
