So I can't help pondering on what appears to be an interesting situation.
Anyone who wants to argue that the black swan is about refraction and isn't about the existence of horizons runs the risk of looking complicit in the hiding the secret.
(I had to comment since there's no end to this confusion.)
The black swan is neither
. At least not according to the author cited by @Rory in this post
on the second page of this thread. It's that
author who is the one invoking the modus tollens scheme of "John" a.k.a. Quantum Eraser and that author only
that I've been commenting on when discussing the 'black swan' invoked by the FEer against the glober.
According to that
author the black swan is about the horizon in the oil rig photo being too far for globe to be true
. To that
author the black swan is not
about whether the horizon exists at all nor
is it about refraction. I have no clue nor interest in what other
black swans other FEers invoke to disprove globe.
And once more: The main issue in QE's calculation -- which we've revisited until nothing but mouldering bones are left of the dead horse -- is that it deals with a geometric horizon
while the oil rig photograph invoked as proof of the too-distant horizon demonstrates strong refraction for everyone to see and is, therefore, evidently for any sensible person an apparent horizon
(read: heavily refracted horizon, further away) rather than a geometric one (read: non-refracted which would have to be closer). If
the oil rig photo in actual fact shows the geometric horizon, the modus tollens argument of QE would be valid and the black swan thereby demonstrated.
And of course
, the hardline FEer would never
accept refraction as a factor. Because if he would and if it were included in the QE's calculation of the distance of the horizon, he'd be calculating the distance of the apparent horizon
which would indeed be far away and would match globe geometry just fine. Neither
will the hardcore FEer ever admit that the oil rig picture contains clear evidence of refraction that would explain both the heavy distortions on specific features of the photograph and the significant distance of the horizon behind the oil rig.
I hope we can settle this once and for all.
