What you have succinctly defined is scientific theory. Something we may never know for sure but worth exploring 
to prove one way or another.

Also, you have indirectly brought up "settled science", a term that is a bit frightening. Who defines what 
science is beyond all questioning or what "we can never know" and sets that as unworthy of further exploration? 
It really does not take much thought to know who those are, since they have been with us since someone formed an 
opinion.

There is no settled science. All science is worthy of exploration and rational debate no matter how certain it 
might seem to be. Take, for example, the bee dance.
