Whether or not light or time perform as Einstein predicted in all instances in times to come, at least
the 'observations'(ie. models and predictions) about geometry and light and time
are coherent, testable, refutable.
Some of the 'observations' have been experimentally tested. Are you saying the ones that were confirmed were confirmed by mistake or deception?
The observations about geometry are permanently true in their defined context.

Are you saying these about the details of the afterlife which the "Theory of Purgatory" represent? I thought that was about dingy basements administered in this life by
unhappy, frustrated minions of the Light Bearer,
(not Rye Krisp, the other one )
I would say more, but then it wouldn't be "would" any more.
