Re: Forgive my ignorance but...
Hmm. If a theory is "really hard to disprove" then it starts to flirt with being non-scientific (in Karl Popper's terms*), and starts to become philosophy/religion/superstition (delete according to taste) instead.
However, I agree that we're probably between theories at the moment, both with Cosmology and Physics. The Dark Matter problem needs some testable assertions, and Quantum Physics has gaps that we're filling arbitrarily (even though it makes very successful predictions). So, I wait with eagerness for the new theories to come along, with better explanations.
* Interestingly enough, according to Popper's principles, Astrology can be called a scientific theory, as it makes falsifiable assertions ("you will meet a tall handsome stranger..."). It's just that it' keeps getting proven wrong.
