Not to quibble too much, but Warp is talking "Hypothesis", not "Theory",
and you are not really helping. A Theory has to be "supported by
evidence", a hypothesis is merely a possible explanation, whether
testable or not. Something doesn't become a "theory" until its not just
been tested, but provisionally passed such a test. Its still only a
hypothesis *until* you test it, and receive results that confirm that it
*can be* called a theory. That is why gravity gets the pass, in that you
can test "if" it exists and what it does, even if you don't have a
theory that really says "why" it does so, while, "I have invisible pink
unicorns in my garden", can't go past being a hypothesis, there being
no way to prove they exist, that they "do" anything, never mind why they
are there.
Its a distinction that gets rehashed about once a month on
scienceblogs.com when dealing with lay people and various alternate
reality wackos that equate "theory" with "hypothesis", and both with
"wild guess". If you want to talk the talk, lets not confuse the rubes
(or embolden the loonies), by using their sloppy definitions. ;)
