4. The "free fall" speed of the buildings falling somehow cannot coexist with a building collapse due to gravity after structural failure from planes hitting buildings.
...asserts that if X is the speed of the fall of an object in air, then a building collapse should be X - Y speed. Where Y is resistance by the part of the building below the section falling on it.
This argument is flawed in it's premises, it's approach, and in it's conclusion.
The "free fall speed" is V = 32 ft * time^2/seconds.
Roughly in the first second, an object moves 32 feet. In the second second, 64 feet, and so on.
I'm not seeing support for #4 either in the video of the towers collapse, the seismic records, or in the math and structural stuff.....
Nor are you taking into account many other factors that show that buildings like these can not fall in free fall style as they did, without some critically timed detonations going off inside to make them fall that way.
If we wanted to use odds, it couldn't happen with one building. Three buildings in the same day equals demolition equals an inside job.
But these are huge numbers for the energies, regardless of exactly what that exponent is.
Oh, and there is no such thing as "odds" here. There seem to be two lines of thought among conspiracy theorists. First there is the belief that the initial structural failure could not have occurred without "additional assistance" such as thermite or explosives. Second there is a belief that the downward pancaking of the towers must have been accompanied by additional explosives or thermite, such as charges on each floor or something of that sort.
In my opinion the first is a valid question, and should be explored and answered. We can do that pretty easily. Also in my opinion, the second is way over in batshit crazy land.
Actually, odds is all there is. I don't mean the odds in chemical reactions, or the odds in math. I mean the odds that the chemical reactions and the math that you stress apply to 9/11. The reason? Because there were all kinds of other activities going on that you don't take into account in your chemistry and math application.
Name one? Nobody knows what amount of the fuel was on board the planes. Nobody knows what percent of fuel was boiled off before it could burn. Everyone can see that the almost perfect collapses, if they happened because of the fuel, would have had to have the perfect amount of fuel added to the absolute correct places in the Towers, or the Towers would have toppled well outside of their footprints.
These simple points make all your math and chemistry irrelevant, except if it is applied to explosives already placed in the buildings.
