Newton's third law of motion is clearly stated. Any attempt by you to change Newton's words to support your version of events or understanding of science is clear proof that you are playing by your own rules and reject whatever you don't like.
The list of things that you don't understand just never gets any shorter, does it? The force of gravity between the Earth and the building are equal and opposite to each other. When the building was standing, the contact force and reaction between the two were also equal and opposite to each other, but that's a completely different force. When the building was standing, the contact force must have been
equal to (but not the
same thing as) the gravity force, because it they weren't equal, the building wouldn't stand up. When the top mass was set in motion, the impact forces in the collisions were also equal and opposite on the colliding objects, but
there is absolutely no reason to think they were equal to the force of gravity. In fact, the collapse is simply convincing evidence that they weren't equal. I have not "change[d] Newton's words to support [my] version of events or understanding science"; you simply don't understand how to apply them in a real-world situation.
There is no reason for me to summarize anything. Cole's video stands on its own.
If you could state Cole's argument in your own words, it might help in pinpointing where your reasoning fails you. But I suspect you are correct: there's no good reason to waste time doing that.
Once again you claim he is wrong, yet you have not performed any experiment to prove he is wrong.
You keep saying that, and yet the experiment in the NMSR video proves Cole is wrong. Instead of realizing why that's so, you try to weasle out of it by suddenly realizing that that model is not an accurate dynamic model of the WTC towers -- which it was never intended to be, unlike Cole's models. It does, however, show quite clearly that there must be something wrong with Cole's reasoning: the collapse proceeds all the way down, apparently never once violating Newton's laws. Verinage demolitions, Ronan Point, and Skyline Towers are also proof that Cole's conclusion must be wrong -- progressive vertical collapse
can go through any number of floors without explosives -- and again, you try to dodge that by saying they weren't the same type of construction as the WTC. That's about as self-refuting a rebuttal as I've ever seen: Cole's small-scale models (which bear no pertinent similarity to the WTC towers) are supposed to tell us something about the WTC, but full-size building collapses don't tell us anything unless they are exactly the same construction as the WTC. What a hoot.
