The two most important words we know about the physics of 9/11 are: molecular dissociation
Analyses of air samples from the 9/11 WTC (""Ground Zero"") particle plume reveal the unexpected presence of many particles smaller than 1 micron (ie, nanoparticles). Among the smaller GZ particles, the distribution of their sizes clearly indicates that they were caused not by pulverization but by widespread molecular dissociation, which occurs only at energy levels higher than what could result from a collapse or even what can be achieved through the use of conventional weapons technology.
When matter is elevated to temperatures hotter than the surface of the Sun, molecular dissociation results. Molecular Dissociation (MD) is easy to understand once we realize that there are four (4) states of matter: solid, liquid, gas, and plasma. Just as ice has trouble surviving in water or steam, molecules have trouble surviving in plasma, which is highly energetic (ie, extremely hot). When molecules dissociate, they leave behind loose atoms and fragments of molecules. In other words, extremely small particles. In this sense, it is correct to think of molecular dissociation as disintegration.
Disintegration chambers based upon this principle are available; other forms of energy can also break down molecules. When molecular dissociation occurs, covalent molecular bonds are broken, but atomic bonds survive. The resulting particles -- loose component atoms and fragmented molecules -- are far tinier than what occur in any conventional explosive event, including the most violent volcanic eruptions:
Recognizing what happened at Ground Zero is key to understanding it. And vice versa.
There is no known "pulverization" mechanism which can account for so many unnaturally-tiny nanoparticles at Ground Zero. There are also other highly unconventional aspects to the devastation of the 3 WTC skyscrapers at Ground Zero, all of which indicate the release of an enormous amount of excess energy (heat), which has never been accounted for:
So once we confirm evidence of widespread molecular dissociation having occurred at Ground Zero in New York City, we have a very strong indication that only exotic, unconventional weaponry could have released that much extremely -- unimaginably -- high intensity energy which suddenly appeared just as the towers disintegrated from top to bottom. This understanding means we cannot blame the highly unconventional Ground Zero devastation on thermite/thermate/superthermate and "controlled demolition" any more than we can blame it on "jet fuel" or "box cutters".
The precise form and source of the extraordinary energy release at Ground Zero remains a mystery. However, the same BYU physics professor -- who just happens to be an expert on nuclear fusion -- who's been trying to keep people from considering the involvement of any exotic forms of energy has been caught lying about fusion triggers (1 2 3 4) and thus falsely trying to rule out the possibility of any kind of nuclear devices having been employed at Ground Zero. audio
