Zero responses from anyone attempting to say what the testable theory was. Zero.
At this point, it's clear that the official narrative cannot undergo the kind of scrutiny that the CD Thermite theory has already undergone and survived. The CD theory is, by objective standards (not my personal ones), a better theory than the official explanation as well as all the other tin-hat productions, (i.e., DEW, No-Planes, Nukes, etc.)
Now we can throw the "NIST Theory of Collapse" into the basket with the rest of the untestable, low-explanatory-power theories like "space beams" and "holographic planes."
So, if the defenders of the official story don't have any scientific confirmation of their favorite pet theory, what other kinds of nonsense do they subscribe to? If "reasons" don't matter, why not believe in Vincent, the All-Powerful sea otter who inhabits the toilets of people who deny science? You have as much reason to believe in Vince as you do the official narrative. No one has tested for the existence of Vincent, so in your world, that's as iron-clad as the official story.
If you say so Jay,
You have done your scientific research, got all the answers, what now ?
