Poverty is due to moral lacking

[Thorne]

All theories are subject to testing!

Not necessarily. From a book I'm reading: "... only that which is experimentally observed, or that which can be logically connected to experimental observation, has any reality."
There are some things which cannot, yet, be directly observed. They can be logically deduced, based on other observations, but not measured directly. A black hole is a perfect example. We cannot see what happens inside the event horizon, but by observing effects OUTSIDE, scientists can deduce what is happening inside. They can then predict OTHER effects which SHOULD happen if their hypotheses are right, and if those effects are observed the theory is strengthened.

Factually true I agree. But this could be considered a form of testing.
