So it was an energy weapon now? Incidentally, those steel beams, how do they know its steel and not concrete?
I'm guessing there were some massive forces in play when an object that weighs one and a half million tons collapses, fire may not disintegrate concrete but pressure can.
We feel what we feel on the flimsiest of evidence. The traveller who drags his feet only raises dust.
People more qualified than you have used physics to prove steel framed buildings don't dissapear into a puff of dust . You can guess what you want If it brings you comfort.
They turn from being 110 floor skyscrapers to dust in seconds There are videos online to show how they dissapeared . Before After
Those are some huge dust particles. If you squeeze your eyes tight they almost look like the remains of a 110 storey building.
If you squeeze them a bit tighter and put your fingers in your ears you can almost believe the official explaination .
The buildings did not disappear though did they? I mean, they found people alive in there, unless the firemen and rescue teams found the survivors under piles of dust? A lot of money was spent bringing in cranes and other heavy lifting material, seems to me they could have just brought a couple of Dysons.
