The physics of 9/11 including how fast and symmetrically one of the World Trade Center buildings fell prove that official explanations of the collapses are wrong, says a Brigham Young University physics professor.
In fact, it's likely that there were "pre-positioned explosives" in all three buildings at ground zero, says Steven E. Jones.
In a paper posted online Tuesday and accepted for peer-reviewed publication next year, Jones adds his voice to those of previous skeptics, including the authors of the Web site www.wtc7.net, whose research Jones quotes. Jones' article can be found at www.physics.byu.edu/research/energy/htm7.html.
Jones, who conducts research in fusion and solar energy at BYU, is calling for an independent, international scientific investigation "guided not by politicized notions and constraints but rather by observations and calculations.
"It is quite plausible that explosives were pre-planted in all three buildings and set off after the two plane crashes which were actually a diversion tactic," he writes. "Muslims are (probably) not to blame for bringing down the WTC buildings after all," Jones writes.
As for speculation about who might have planted the explosives, Jones said, "I don't usually go there. There's no point in doing that until we do the scientific investigation."
Previous investigations, including those of FEMA, the 9/11 Commission and NIST (the National Institutes of Standards and Technology), ignore the physics and chemistry of what happened on Sept. 11, 2001, to the Twin Towers and the 47-story building known as WTC 7, he says. The official explanation that fires caused structural damage that caused the buildings to collapse can't be backed up by either testing or history, he says.
Jones acknowledges that there have been "junk science" conspiracy theories about what happened on 9/11, but "the explosive demolition hypothesis better satisfies tests of repeatability and parsimony and therefore is not 'junk science.' "
In a 9,000-word article that Jones says will be published in the book "The Hidden History of 9/11," by Elsevier, Jones offers these arguments:
The three buildings collapsed nearly symmetrically, falling down into their footprints, a phenomenon associated with "controlled demolition" and even then it's very difficult, he says. "Why would terrorists undertake straight-down collapses of WTC-7 and the Towers when 'toppling over' falls would require much less work and would do much more damage in downtown Manhattan?" Jones asks. "And where would they obtain the necessary skills and access to the buildings for a symmetrical implosion anyway? The 'symmetry data' emphasized here, along with other data, provide strong evidence for an 'inside' job."
No steel-frame building, before or after the WTC buildings, has ever collapsed due to fire. But explosives can effectively sever steel columns, he says.
WTC 7, which was not hit by hijacked planes, collapsed in 6.6 seconds, just .6 of a second longer than it would take an object dropped from the roof to hit the ground. "Where is the delay that must be expected due to conservation of momentum, one of the foundational laws of physics?" he asks. "That is, as upper-falling floors strike lower floors and intact steel support columns the fall must be significantly impeded by the impacted mass. . . . How do the upper floors fall so quickly, then, and still conserve momentum in the collapsing buildings?" The paradox, he says, "is easily resolved by the explosive demolition hypothesis, whereby explosives quickly removed lower-floor material, including steel support columns, and allow near free-fall-speed collapses." These observations were not analyzed by FEMA, NIST nor the 9/11 Commission, he says.
With non-explosive-caused collapse there would typically be a piling up of shattering concrete. But most of the material in the towers was converted to flour-like powder while the buildings were falling, he says. "How can we understand this strange behavior, without explosives? Remarkable, amazing and demanding scrutiny since the U.S. government-funded reports failed to analyze this phenomenon."
Horizontal puffs of smoke, known as squibs, were observed proceeding up the side the building, a phenomenon common when pre-positioned explosives are used to demolish buildings, he says.
Steel supports were "partly evaporated," but it would require temperatures near 5,000 degrees Fahrenheit to evaporate steel and neither office materials nor diesel fuel can generate temperatures that hot. Fires caused by jet fuel from the hijacked planes lasted at most a few minutes, and office material fires would burn out within about 20 minutes in any given location, he says.
Molten metal found in the debris of the World Trade Center may have been the result of a high-temperature reaction of a commonly used explosive such as thermite, he says. Buildings not felled by explosives "have insufficient directed energy to result in melting of large quantities of metal," Jones says.
Multiple loud explosions in rapid sequence were reported by numerous observers in and near the towers, and these explosions occurred far below the region where the planes struck, he says.
Jones says he became interested in the physics of the WTC collapse after attending a talk last spring given by a woman who had had a near-death experience. The woman mentioned in passing that "if you think the World Trade Center buildings came down just due to fire, you have a lot of surprises ahead of you," Jones remembers, at which point "everyone around me started applauding."
Following several months of study, he presented his findings at a talk at BYU in September.
Jones says he would like the government to release 6,899 photographs and 6,977 segments of video footage for "independent scrutiny." He would also like to analyze a small sample of the molten metal found at Ground Zero.
And, er, maybe the buildings were designed to collapse cleanly?
And didn't Al Quada, in fact, complain that the buildings didn't topple, as they hoped?
He probably also believes God can be found in a hat.
And physics tells him THAT precisely how.
I'll wait for his "physics" paper that disproves the Holocaust.
That will be he next thesis.
So, did a plane loaded with fuel crash into WTC Building 7?
Just wondering..................
What about having the physics of a 20 story weight smashing into a 80 story base from 30 feet up. That's what looked like it happened. Also, just because a diesel doesn't burn at a certain temp in an engine or beaker doesn't mean it would not burn at that temperature in an oven. The WTC made a nice oven with the windows popped out. Remember our ancestors used to make steel with WOOD fires and CHARCOAL both of which burn at much lower temperatures than diesel in the open. But when put into a furnace get hot enough to melt steel.
1) by the huge amount of jet fuel that was burning there from much larger planes than were ever expected or allowed for; 2) the environmentalist decision to stop cladding the steel with asbestos beyond the lower floors; 3) the domino effect of the top floors collapsing onto the floors lower down.
Add to that the damage that is done when you ram airplanes weighing several hundred thousand pounds each into the structures at 600mph.
Check it out. He is into Cold Fusion.
Any boot Marine or Dog Face knows that thermite isn't an explosive. It is an incendiary. I would think a high caliber expert like Dr. Jones would have picked up on that fact.
There is an old method for cutting the tops off of glass cylinders; you soak a string in alcohol, tie it around the line at which you want the separation you want to take place and light it.
After it burns itself out, spray ice-water on the glass at that line and tap it sharply.
In that case, there is no column load; to demonstrate the effects of fire on a column load, I suggest you take an aluminum can and place a brick on the top, soak a similar string, tie it around the approximate upper part of the cylinder where the impact and resultant fire would have been on the towers, light it and see how much of the can deforms through gravity.
Of course the towers weren't cylinders, and the collapse was seen only from outside; what made it remarkable was that the structure seemed to come down through itself.
So, did a plane loaded with fuel crash into WTC Building 7? Just wondering..................
The 110 story buildings were structurally devasted by the impact of the jet planes.
WTC 7 was structurally devasted by the awesome power released by the collapse of two 110 story buildings partially on top of it.
Stuff fell on it.
Bodies fell through windows in apartment buildings all the way over by Battery Park City. The fall was neat, but not all that neat.
It would have been and engineering marvel to have the explosive pre-positioned at the point of impact of the planes. Why didn't they explode when the planes hit the building?
OK,
This is what you get from someone who takes ID Physics.
If you go through this guys CV, he is something of a Nuclear/particle physicist. Maybe his classical physics is shaky these days. I think I will trust STRUCTURAL engineers over this guy. Of course, the loonies will see him as the WORLDS AUTHORITY on structural demolition..
How about this explanation... It was a MIRACLE. Call me a kook. I don't care. I believe that God kept those buildings from falling OVER instead of DOWN.
