Now, THAT'S an interesting bit of logic. :-)

Let A = fluid Moon
and B = Moon breaks apart

Now you claim:
A => B

and you "prove" that by claiming that
((NOT B) => (NOT A)) = true
is an observed fact.

But is it? Of course it isn't.
The observed fact is:
((NOT B) AND (NOT A)) = true

The fact is that:
((NOT B) => (NOT A)) = false
of the very same reason as
(A => B) = false

The fact that the Moon hasn't broken apart
doesn't _imply_ that it is NOT fluid,
and a fluid Moon doesn't _imply_ that it
would break apart.

Quite the contrary.
As I have told you several times:

| The critical distance is the Roche limit.
| The Roche limit for a liquid Moon is 2.86 Earth radii.
| The orbital radius is 21 times bigger than that.
| A liquid Moon would do just fine.
| And its shape would be the same.

You didn't get that quite right, did you? :-)

And now we have learned that Androcles is
so stupid that he believes:
((NOT B) AND (NOT A)) = (A => B)
