Anyway, it was a fairly persuasive argument in favor of Radical Timelessness -- basically, if inertia is generated by things in the future, those things must actually, physically exist, and the universe is therefore something that 'is' and not something that 'happens'.
To prove this by making a prediction that wasn't predicted by other theories, they built a 'flux capacitor' that should have generated (tiny amounts of ) inertialess thrust by altering the instantaneous mass of a capacitor and vibraring a counterweight. The originator of the theory posted results that were an unqualified success!
Of course, everyone trying to replicate his results detected no effect whatsoever, as if he had, perhaps, made them up.
Ah, well. I guess causality survives another day.
