As a former "conspiracy theorist", & pro-scientific thinker, I can't help but notice the major errors in the theories on 9/11. When it comes to the inside job theories, I just can't take it as truth any longer. In which I feel the only credible argument the conspiracy theorists held was of a mere misunderstanding - the finding of Thermate chemical signatures in the Twin Towers.
Steven Jones has done plenty of speeches about this in which he points out the chemical elements found within the debris. These elements pointed out are as such: iron, sulfur, aluminum, potassium, manganese, fluorine, & titanium.
Yes, most of these elements can be found in thermate. Jones had this one right. So what's the problem here? Well, like any proper scientist who would conduct studies on these elements, they'd first try & find any natural sources in which these elements could come from. And guess what? They all check out for other natural sources:
Sulfur: The third most common ingredient in the WTC construction was gypsum-based drywall, which is 18.62% sulfur.
Iron: Used in paint & electronic devices.
Potassium: Used in concrete.
Manganese: Used in the structural steel, paint, batteries, & ceramics.
Fluorine: Used in Freon. 200,000 pounds of Freon cooled the WTC complex. This was the largest air-conditioning system in the country.
Titanium: Used in paper & paint & made up 2% of each of the 767's. WTC7 was also clad in polished steel & titanium.
I find the idea of Jones claiming these elements were uncommon & only found within thermate quite disturbing, & at the least illogical.
So what would any professional scientist do next? Well, they would check if these elements were presently in their correct, signature quantities.
According to Steven Jones' own estimates, "about 1,000 pounds of explosives would be sufficient [per tower]". For both towers & WTC7, this would equal about 3,000 pounds of thermate. Thermate is 2% sulfur, in which calculates to about 60 pounds of sulfur. Approximately 1 million tons (2 billion pounds) of dust blanketed lower Manhattan.
So, based on Professor Jones' estimates, a thermate reaction would cause the WTC dust to be approximately 0.000003% sulfur. Correct? (don't worry, it's text. You can get a calculator if needed)
Yet, this would then be highly unlikely for such a low percentage to be detectable, especially when compared to USGS dust samples in which showed as much as 5.4% sulfur!
And finally, what is the last important thing a scientist would need to do in order to confirm the presence of a chemical device? Well, they would need to ensure that all of the elements of thermate are present. So, are all elements present?
I would say no! For the two main byproducts of thermate are aluminum oxide (41%) & barium nitrate (29%). Both are especially unique to thermate & would have no reason whatsoever to be found within the WTC - unless, that is, thermate was in the twin towers.
However, neither the USGS nor Steven Jones himself report finding any traces of either of these elements - the two main ingredients of thermate! Yes, Jones does point out the presence of aluminum, but there's a huge difference between aluminum & aluminum oxide (which has 3 oxygen atoms). Not to mention aluminum was common through its use in the WTC's facade, the 767's, & vehicles.
The presence of all elements pointed out through natural sources within the WTC complexes, & the very lack of aluminum oxide & barium nitrate just completely destroys the theory that thermate was in the WTC!
