Not being able to explain, to your satisfaction, why there is an apparent lack of PB, how the chamber was ventilated or anything else to do with its functioning, has no evidential value.Archie wrote: ↑Sun Jul 19, 2026 4:16 pmYour side's explanation for the lack of Prussian blue (as well as the fast pace of cremation) hinges on super fast ventilation of the chamber. And the "Kula columns" are the purported mechanism by which the pellets were removed from the chamber. Otherwise, the pellets would continue releasing gas for hours which would create all sorts of problems. Hence the Kula columns are crucial to your position.
The Kula columns are not crucial. Only two chambers are evidenced to have had them, so they were not essential to the gassing process. It would not matter even if we did not know about them at all. Not knowing how something worked, is independent of knowing if it that something existed or not. There is corroborating evidence of the existence of the Kula columns, but it is patchy and incomplete and so we are not sure exactly how they functioned. There are lots of things in history we know happened, but lack details of how they happened.
Your argument that we have to know how it happened, or else we cannot prove it happened, is flawed.
