It can in principle be tested by a scientist falling into
the hole. The only problem is that he won't be able to
tell anyone outside what he finds out, but that's a
practical difficulty, not a philosophical one.

A lot of what the early Greeks found out got lost in
various library burnings, etc. Does that mean they
weren't being scientific?

I don't think they're similar at all. Show me the equations
for one of these religious theories and I might change
my mind...
