18 years ago, back in September 9th of 2001, all of us remember the tragic day when two planes crashed with the world trade center in New York, the attack was coordinated by the terrorist organization Al Qaida, which killed 2977 people plus the 19 hijackers, and 6000 more people were injured and this completely destroyed the world trade center, bringing down both towers. But ever since 9/11 conspiracy theories have started to fly, many started to say that it was impossible that the planes brought down the towers, others said it was George W. Bush who coordinated the attack.
Some of the most well known theorists are: Dylan Avery and Jason Bermas, who made a documentary, which stated that “Fires were insufficient to cause their collapse, and that cell phone calls from the hijacked airplanes would have been impossible at the time”. David Griffin, who is a theologian who’s written many books about 9/11. Once known as Fleischmann and Pons’ competitor for 'cold fusion' research in Utah, Steven Jones has written many books about 9/11 Truth. His work with others (including chemist Niels Harrit of Denmark) on detecting nano thermite in WTC dust is frequently cited as “peer-reviewed research” that proves “inside job” claims. The physics teacher David Chandler, has stated that simple physics show that the towers could not have happened from gravity alone.
Now, here are some of the theories that had been made debunked.
First: ‘The twin towers collapsed with a free-fall acceleration in a path of mayor resistance’. This was one of the most bizarre things of 9/11, since each tower collapsed between 15 to 20 seconds. The towers collapsed in free-fall acceleration, which proves that there was a complete lack of resistance, proving he structures were demolished with explosives. We are also told the mass of the building is“80,000 tons of structural steel,” which would definitely resist collapse. But how could it happen, it’s been explained very well in the technical literature by Northwestern’s Zdenek Bazant, PhD, and others. Here are the findings: each floor contained over two million kilograms of mass. The gravitational potential energy of a standing tower with twelve-foot floors extending upward 110 stories can be calculated straightforwardly; it comes to over 420 billion joules of energy, or the equivalent of 100 tons of TNT per tower. This amount of energy was released. This is where the energy required to break columns, pulverize concrete, and expel debris through windows came from.
Second: ‘Nano-thermite and military-grade explosives were found in dust from the towers. Tons of melted steel were found in tower debris’. The reaction of thermite is very hot, but slow compared to common explosives. Real controlled demolitions use explosives to topple large buildings; However the hallmarks of modern demolitions, the boom sound and flashbangs were absent. Richard Gage, insist that high explosives must have been used to bring down the Twin Towers, as they say this is the only process that can possibly explain the “ejection of debris hundreds of feet from the towers.” But thermie in many levels fails as an explanation of the destruction of the towers.
The thermite reaction, which takes place between iron oxide (rust) and powdered aluminum, is practical for welding train rails or engines of vehicles that need to be left behind in combat operations, however it has never been used for and it isn’t practical for controlled demolitions.
Third: ‘Tower 7 , which wasn’t hit by a plane collapsed anyways’. Ever since the crash, it has been a mystery why the WTC 7 collapsed. We were always old that there were a few internal office fires, yet it collapsed late in the afternoon, but it collapsed on its own footprint, meaning that it was most probably a controlled demolition, just like the towers. Yet the WTC 7 collapse fails to prove 9/11 was an inside job. What is often conveniently left out of the story are actual reports from NYFD firefighters at the scene, which describe “huge, raging, unfought fires on many floors at once and visible deformations and creaking of the building prior to its collapse” (Roberts, 2008). Tower 7 was not hit by an airplane; however, it was struck by a 110-story flaming skyscraper, the North Tower. The fires raged for hours, and they eventually caused a critical column (#79) to fail because of thermal expansion. NIST determined that this column was a crucial column, it could even be considered a design flaw. It’s failure would have collapsed the building even without the collision and debris of WTC 1 and the fires.
‘No Planes Theory’: Even though this sounds stupid, there are people who actually think that back in 9/11, what crashed with the WTC weren’t planes, some people said they were holograms, that they were ballistic missiles. It appeared in a video recorded from an helicopter, in which you can see a boeing 767 accidentally appearing from behind a layer mask. According to David Shayler, “the only explanation is that they were missiles surrounded by holograms made to look like planes”, he says, which would be well beyond the capabilities of contemporaneous hologram technology.
Even though there are a lot of mysteries and uncertainties, the most believable or the version that is closest to the truth is that 9/11 was planned by Al Qaeda and two planes brought down the WTC 1 and 2, even though it's hard to believe, that's closest to what could have happened, but the only thing we can be certain of, is that no one will ever know what exactly happened.
