The CD theory of the 9/11 WTC 7 collapse is more scientific than the official NIST fire theory

"For every complex problem, there is a simple solution ... and it's wrong." -- H.L. MenckenWhy was Mencken right about about simple solutions? It's because what seems to be simple is not. A simple explanation is that the sun is transported through the sky on a chariot driven by a god, It explains sunrise and sunset perfectly. Variations with the seasons are perfectl explained by the whims of the chariot driver. The only problem is with the details of how the chariot works.Why did WTC 1 and 2 fall from the top down, contrary to ordinary controlled demolitions? It's because conspirators wanted it that way. Why did WTC collapse from the center outward? It's because conspirators wanted that building to collapse that way. Why did the WTC building have rivers of molten metal when controlled demolitions never do? It is because conspirators used magical thermite that we cannot test. The analysis of any catastrophic failure is not a scientific theory, it is an engineering analysis. Scientific theories deal with fundamental laws of nature that are mathematically formulated and can be tested by anyone at any time. A building collapse or other such investigation is an attempt to determine what happened for that event alone. It's possible that no explanation may ever be found. Unlike a law of nature that can be tested, the event can never be duplicated. It's true that a proposed explanation must conform with known scientific laws -- we will have a discussion of the claimed magical properties of nano-thermite. However, it is not likely that every detail of a catastrophe will be explained, and it's wrong to insist on fanciful theories in that attempt.The simplest theory will always use an agent who arranges all the pieces exactly as observed. The agent at work could be a deity, a being from another dimension, or a conspiracy with unlimited resources that operates with hypothesized weapons in total secrecy. Science plays an important role in the analysis. It's true that an explanation cannot violate he known laws of nature. For example, it's claimed that nano-thermite melts steel into puddles that do not harden when the heat source is removed. that's impossible given the second law of thermodynamics, so whatever the real explanation for puddles of molten metal that persist, the explanation must involve adding heat continually over time.Controlled demolition is a practical impossibleControlled demolition requires tearing the building apart to place the explosives. http://en.wikipedia.org... One expert estimated that it would take a team of a hundred workers several months to prepare just four floors of a World Trade Center building. Controlled demolition has always depended upon tempered steel being brittle. The explosive force of the charge cracks the metal along the line of the charge. The metal is not melted. The charge must be placed in direct contact with the steel so the force is focused on the surface. In the case of the World Trade Center the beams were insulated to protect against fire. So the procedure could be to make holes in the walls, place the charges against the steel, and run wires to the a controller that detonates the explosives in the correct sequence. Ordinarily, only the bottom floors of a building are prepared and gravity provides nearly all the energy for bringing down the structure. Even though there are no explosives on upper floors, the building collapses at close to free fall speeds. That's because the steel fractures rather than bends. It can bend a little -- you can flex a glass rod a little -- but it breaks upon impact by explosives.The World Trade Center building collapsed from the top down, implying enormous amounts of preparation, and ruling out any sort of controlled demolition. The WTC 7 building collapse started at a point closer to the bottom, but the preparation work would still be impossible to have been conceal from building occupants. NIST correctly rejected controlled demolition theories early in the investigation for that reason. One of Pro's video suggest that the demolition could be accomplished by placing nano thermite inside box beams to melt the steel rather than crack with explosives. That make the preparation job more difficult. A the video shows, special fixtures would have to be installed to hold the thermite. the theory claims that every floor must have been prepared, otherwise the building would not have reached free-fall speeds. That would take a doubly impossible amount of preparation time and manpower.The NIST team included 200+ scientists and engineers, half from academia and industry. It's a practical impossibility that all could have been convinced to cover up the murders of thousands of people. The mafia cannot keep criminals from talking. It's not plausible the government could suppress so many independent people. A conspiracy theory can be dismissed out of hand.The NIST analysis of WTC 7WTC 7 was originally design with a much smaller floor plan. Near the time of construction the floor plan was expanded so that the original inner core was surrounded by additional structure. That was the building's ultimate undoing. A fire that started in the outer structure expanded the steel and pushed against the vertical support of the core. That deflection cause the columns to buckle. [Imagine some heavy books supported by soda straws. The support is stable until the center of one of the straws is pushed, then it collapses. That's buckling.]The NIST report http://www.nist.gov... is written for engineers. The collapse sequence is described starting on page 21. Debris from the fall of WTC 1 & 2 damaged seven exterior columns of the south and west faces of WTC 7, and started interior fires. The fuel within WTC 7 was equivalent to 32 kg of paper per square meter. The sprinkler system failed in the building due to failure of the water supply, and due to the same lack of water, the Fire Department could not extinguish the fire. The intense fire caused the heated steel to expand, which placed stress on adjacent columns.Structure Magazine summarizes. "A collapse mechanism analysis performed for the removal of column 79 produced a deformed shape with kink in the roof of the east penthouse, as captured in actual videos and photos taken that day." http://www.structuremag.org...The building collapsed starting from the core. Video of the building shows that the penthouse in the center of the top floor began to descend before the outer walls. Distortions in the wall near the fire also agree with the theory. Fire fighters in the building heard it creaking earlier, a sign that the building was under unusual stress. The NIST simulation agree with the observations.The alleged science of nano thermiteNano thermite is revealed in government reports concerning it's potential used as an explosive. No one outside of the military has access to nano thermite, so it's actual properties cannot be verified. An explosive could be used as a shaped charge to fracture the steel in a controlled demolition. Since it's more powerful than conventional explosive comparatively little would be required. CD theorists insist it was used that way because of reports of explosive sounds. But if that's true, what produced the rivers of molten metal? Melting tons of steel would require tons of thermite. Thermite can melt steel, but so can charcoal with a bellows. Tests couldn't get a puddle of steel with 125 pounds of thermite. The intrepid conspiracy theorist focused melting in a small area using a fixture, but that makes rivers of steel even less likely. On the other hand, why didn't 300,000 pounds of burning jet fuel manage to melt the tons of aluminum in the aircraft? What is the science behind steel that melts so easily while aluminum resists?The conspiracy theory defies logic and science.
