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

Simplicity is not demanded for complex eventsPro began the debate with the general claim that science demands that simple theories must be preferred over complicated ones. I pointed out that while that's true for physical laws like gravity it's not true for inherently complex occurrences like building collapses or other disasters. According to Pro's claim of simplicity, scientists ought to be compelled to accept a theory that space aliens built the pyramids and other ancient structures, rather than figuring out complex construction techniques. Contrary to Pro, scientists are reluctant to accept the simple explanations of divine intervention, space aliens, and conspiracies. Pro ultimately dropped the contention.A conspiracy could not be kept secretA controlled demolition can be ruled out because preparation for the demolition would surely be noticed by building occupants. According to the Pro's video, steel fixtures must be bolted in place in contact with the beams and then filled with thermite. To do that, the beams must be exposed and the insulating foam removed before being drilled or the bolts to hold the fixtures. I did not argue that radio controlled detonators could not work. I argued that the antennas required would have to be somehow concealed and that would add to the preparation effort. No expert on controlled demolition has claimed that the preparation could be done while unnoticed. Pro produced no experimental verification that it was possible. Moreover, to produce the large quantities of molten metal claimed to be iron claimed by the theory tons of thermite would have to trucked in and secretly put in place. It's not a practical possibility.A conspiracy can also be ruled out because secrecy could not be maintained. Pro claims that the NIST simulation is an obvious fraud and that it explains nothing. If so, all the 200+ engineers and scientists, half from outside the government, must be a part of the fraud. Pro argues that they might be under secret gag orders or that they might have been threatened with loss of their jobs if they exposed the conspiracy. Half of them returned to their jobs in industry and academia, so the threat of job loss was inconsequential, More significantly, we are talking about covering up the murders of 3000 people. There is no chance that a gag order could possibly prevent all those professionals from exposing the conspiracy. The mafia cannot keep it's criminal members from talking, not even with credible death threats. NIST analysts were ethical professionals from a broad cross section of society, not criminals or fanatics. It's inconceivable that all would be complicit in mass murder.The impossibility of keeping the conspiracy secret is enough to discredit the conspiracy theory. The idea that a gag order would be effective is so implausible that Pro's case fails on that alone.Science contradicts the rivers of molten metal from thermitePro insists that claims must be proved. What is Pro's proof that thermite can produce rivers of glowing molten iron? 125 pounds of thermite didn't do it. The experiment with a fixture did not produce a drop of glowing molten metal. Yes, the iron melted. However, the whole point of the experiment with a fixture was that the thermite could be focused so that a minimum amount of heat energy is required. The cited patent accomplishes the same thing; a relatively small amount of thermite, ten pounds, might cut a beam by keeping the cut very narrow. That way not much heat energy is required. But that's not enough heat energy to keep the metal from hardening again almost instantly. Pro's video shows that. I challenged Pro to explain, and he argued that vast quantities of thermite were used. That makes all the technology from he fixture and the patents cited irrelevant. But if the explanation is that in fact tons of thermite were used, then it must be explained how the building could be prepared with that much thermite with no one noticing.The CD explanation does not agree with the science of explosives. An explosion is combustion so rapid it produces a shock wave. In demolition, the focused shock wave cracks the steel. The advantage for demolition is that a very small amount of explosive energy can bring down a building. But if thermite were used as an explosive, then there would be no molten metal at all, just as there is none when detonation cord is used conventionally.If thermite can be used as a demolition explosive, there would be no reason t prefer it over conventional explosives. Pro says that thermite was used in building demolitions, but those were not controlled demolitions and not explosives. Pro's video says thermite was preferred because it would work silently, without attracting attention. If so, then there wouldn't be explosive sounds, which the theory is also supposed to explained.I reference the FEMA report giving a scientific explanation of the eutectic formation and iron micro-spheres. Pro dropped the contention. Pro speculates that both thermite and conventional explosives could have been used, but gives no reason why.Pro never attempted to explain the science of how thermite could melt iron and keep it molten for days without adding heat.Molten metal is better explained as aluminumMolten aluminum makes sense. In each WTC Tower, there was an aluminum airplane and 300,000 pounds of jet fuel to melt it. In WTC 7, there were aluminum furnishings and structure and an uncontrolled fire that raged for seven hours, well fueled by paper and interior wood and carpets. There was much less molten metal in WTC 7.We don't know why it glowed yellow. Jones didn't rule out all organic contaminants as a possibility, just what he tried under the conditions he tried it. If it wasn't an organic contaminant, then it was something else mixed in. Aluminum forms alloys with more than twenty other metals, and while carbon doesn't dissolve, it is used as a dispersant in aluminum. We don't what is was in the mixture of materials that caused the yellow glow, but Jones made no attempt to recreate the mixture that would have been present from building materials and furnishings. All collapsing buildings approach free fallThe kinetic energy of the falling is many times that needed to break the steel. Pro claims that science demands that some energy must go into breaking the building, so that it cannot be precisely free fall speed. That true, but the energy consumed by breaking is so small as to be negligible, particularly on lower floors after the momentum is built up. In conventional CD, the energy of few hundred pounds of explosives brings down the building, and that's negligible compared to the potential energy in the building. The building is pulverized because when the material hits the ground, and the kinetic energy is transferred to the material. The claim that there must be a substantial energy from explosives is bad science. Debris removalLocating victims and removing bodies always takes precedence over preserving the scene. " ... the 1.45 million tons of debris were sent to Fresh Kills, an old landfill on Staten Island. Using rakes, sifting tables, and heavy equipment, workers spread out the debris and meticulously examined it for even the smallest pieces of evidence. The site was staffed by members of the FBI, FDNY, NYPD, and other government agencies. In all, 54,000 personal objects were recovered and 1,200 victims identified." http://americanhistory.si.edu...SummaryStandard procedure is to use simulations to investigate disasters. There is no way to repeat the event, so it's the only method available. Pro claims that the NIST simulation doesn't match the video evidence, but the 200+ engineers and scientists who worked on it think it does match, Independent assessment by experts at Structure Magazine agree. NIST makes many references to observed evidence, which stand unrefuted.The NIST report best represents the science. The resolution is negated.
