Magnetic forces to blame for 9/11 tower collapse

By Steve Connor

Wednesday, 10 September 2008

Scientists can finally explain why the Twin Towers collapsed on September 11, despite the temperature of the fires being well below the 1,500C melting point of the steel girders holding up the buildings.

The discovery that unusual magnetic forces within the girders made them weak at temperatures of about 500C explains away the conspiracy theories that have spread like wildfire since the disaster.

Sergei Dudarev, of the UK Atomic Energy Agency, found that steel loses its strength above 500C because its molecules undergo a physical transition from one state to another due to magnetic fluctuations. "The steel didn't melt, it just became soft. It is an unusual state and the temperatures in the Twin Towers were high enough to cause it because the thermal insulation was knocked off the girders through the impact with the aircraft," he said.

"Understanding how materials behave means we can find the right 'medicine' to make steel stronger at high temperatures... and if our work can be used for other applications, such as safeguarding tall buildings against disasters, so much the better," he said.

It's not an unusual state. Any blacksmith can tell you that when heated at temperatures well below the level produced in the WTC fires, steel and iron weaken and become malleable. Some conspiracy nuts think that the only way steel can weaken is if it's heated to complete liquification; they were only demonstrating their own ignorance.

And, by the way, some nut started the story of a pool of molten steel at Ground Zero, still liquid days after the collapse. Simply impossible. Even a nuclear explosion wouldn't have that effect. Nobody did a metallic analysis that showed this was steel or any other normal metal. What was seen was a greyish puddle of a variety of fluids, including water, paint, melted plastic, various industrial liquids, that had mixed together from the fire, collapse and fire fighting efforts at the WTC.

Yawn.

Strawman Argument
"Straw man" is one of the best-named fallacies, because it is memorable and vividly illustrates the nature of the fallacy. Imagine a fight in which one of the combatants sets up a man of straw, attacks it, then proclaims victory. All the while, the real opponent stands by untouched.

Inevitably we get an endless redux of the same shabby shopworn tactics to buttress the "Official Conspiracy Theory®" over and over and over again.

Does anyone who has looked at the situation seriously suggest that liquefaction was neccessary for the towers to collapse?

NO. They do not and you can produce no reference or quote, from a credible researcher, to support your poor lame Straw Man.

On the flip side neither can you produce any credible evidence or authoritative, based on actual engineering science, explanation as to how the towers collapse symmetrically, uniformly, within 1 hour, and how the initial collapse was initiated simultaneously in 360 degrees by fires localized in limited areas; which the one fire crew to reach the scene radioed back required only 3 Hose Crews to "knock down the flames".

It is amusing to watch the "Official Conspiracy Theory®" morph over time and yet remain so much the same: "19Arabswhohateuscuzwe'refree" directed by a madman in the mountains of Tora Bora, with his "Magic Cellphone©", highjacked 4 airliners, in the most controlled airspace on the planet with box cutters and Pepper Spray, while striking such lightning speed and professional coordination as to prevent all 4 from broadcasting the 4 digit highjack code - following a final night of boozing and whoring while conspicuously leaving a Koran in a Bar (disregard that as these were fanatically devout Muslims to who such activities are prohibited by their fanatical religious laws), cast a spell to put NORAD to sleep, and then proceeded to leisurely crash 3 of those planes into massive structures built of interlocking reinforced steel girders (as much as 4 feet thick in places) causing them to tumble as though made of toothpicks neatly into their own footprints at nearly freefall speed.

It is almost breathtaking each time I see someone travel again down and around the FruitLoop attempting to float the latest preposterous planted explanation to justify the "Official Conspiracy Theory®".

We have gone from jet fuel to office fires to not even mentioning a source for the heat but just asserting that it somehow magically existed.

Of course even NIST and FEMA have been forced to admit that the Jet Fuel, initially used to justify the collapse, all burned up in the first ten minutes, and that Class Alpha Office Fires don't get hot enough to weaken steel. And yet each and every time we get a defender of the "Official Conspiracy Theory®" they always come back to some form of "incredible heat weakened the steel" cause by yet another in a succession of preposterous mechanisms for localized fires to create a uniform, symmetrical, simultaneous, collapse in 360 degrees, while not accounting for the resistance of the underlying structure to collapse. For a theory to be valid it must account for uniformly, predictably, and reproducibly, ALL of the observed phenomena. Yours, as usual with all shills/government apologists, does not. Of course there was one thing uniformly demolished - your argument.

And, by the way, some nut started the story of a pool of molten steel at Ground Zero, still liquid days after the collapse. Simply impossible. Even a nuclear explosion wouldn't have that effect.

The "nuclear explosion" quip is another delightful introduction of our old friend the Strawman.
Nuclear debris still producing radioactivity could, in a confined space such as a rubble pile, continue to generate sufficient heat, YEARS after the fact, to keep molten or near molten steel trapped near it in the rubble pile. Earth to Mikey/Shoonra - that is why Nuclear Piles require "cooling" water. They use it to, uh, prevent the pile from melting the containment vessel (as well as damp the reaction).

Unfortunately for your specious argument there exist a number of videos showing the recovery of molten debris up to 8 weeks after the Towers collapse.

A couple are located here

It is just so unfortunate for your childish petulant denial that the recovery of molten material from the Ground Zero was been recorded on more than one video. As well as having multiple witnesses attesting to the fact. I do not have to provide an explanation to simply show that your argument is false so don't even try that one. You are welcome to try and explain away documented evidence - that should be most amusing.
