Consider the following statement:
"However, it has not been checked whether the recent allegations of controlled-demolition have any scientific merit. This present analysis proves that they do not."
This is a false and misleading statement.
It is probably intentionally misleading.
The paper in question addresses an overly simplistic "physics problem".
To the degree that the mathematical argument has merit, it certainly doesn't address the question of whether the "allegations of controlled demolition have any sceintific merit".
The claim that it does is not true if unintentional, and an explicit lie if intentional.
Why do the theories of controlled demolition have Scientific merit if they do not match the available empirical evidence?
Thermite does not survive the fires and impacts, explosives degrade in fires I have personally tested them they do not work, I even tested Ammonium perchlorate.
Heat weakening has the most merit but there should be considerable amount of evidence from that.
There is no evidence of Monroe effect on any beams or shock waves from explosives.
I mean Scientific theories should have some science behind them, oh yes I do know that there are ways simple ways it could have been done, but that is just me jumping to assumptions without evidence.
Controlled demolition in every theory that I have seen is falsified by the problems in the theories.
Most of which were actually proposed by the truth movement and Controlled demolition theorist themselves.
Even when one of the theorist in controlled demolitions gives evidence it turns out to be just some random reactions or contaminants I mean they do not even know what to look for.
At least I know what would and what would not be evidence of Thermite, It would be a solid sphere of iron with aluminum, and other trace compounds with mineral formations not present below a certain temperature.
IT would not be Fe 3O4 that can form at much lower temperatures do to lewis acids.
I mean did anyone see the northern lights over New York city, or a laser beam?
How many people were fried by microwaves that day?
Give me something anything at all for which there is evidence, and which is reasonable, Please?
You could demolish the buildings with a hammer, damage enough insulation, and the crash a plane into it, water will work as well, I can tell you a thousand ways however there is no proof no scientific empirical data, or verifiable evidence that any were used.
