Re: the psychological warfare on the subject of 9/11/2001
wrong... The columns' resistive capacity had nothing to do with the floor collapse. Once a threshold destructive mass destroyed one floor it added that floors mass and then destroyed the one below and arrest was impossible. No WTC floor could resist more than a few times its static design load. You are aware that the floors were designed to support a specific load? What happens when that load is exceeded by 10 or 20 times? Or 50 or 200? or the load is dynamically applied.. that is the difference between resting a hammer on your head and swinging it hitting your skull... same hammer different force on the skull.
You don't understand the basic physics here.. though you think you do.
Talk about cartoonish conceptions! Bowling balls and glass!? The top few floors of the buildings were made of the same stuff and the rest of the buildings. The calculations have been done: total symetrical collapse due to gravity is an impossibility. The "collapse" should have ground to a halt about 2/3 of the way up. And, with 47 core columns offering point resistance, and over 200 other steel columns, the likelihood of symetrical collapse is utterly fantastical.
The law of conservation of momentum would require the falling mass to slow against the resistance of the lower part of the building, until its energy had been dissipated and it stopped. If you want to try to rescue the validity of your model, you'd have to substitute 12 sheets of glass for the bowling ball--and those sheets would have to be spaced apart. As soon as they met resistance they would start to crush upwards, losing energy in collapsing into the spacing between the 12 sheets. This rubble then loses more energy with each sheet it hits on the way down, slowing as it goes, reducing its momentum. There just wasn't enough mass in the mostly empty floors of the towers to feed a continued collapse.
That you tout such an unworthy opinion so strongly in the face of easily available analysis to the contrary suggests either an extraordinary degree of digital incompetence or subterfuge, neither of which recommends you very highly for continued discourse.
