Don't you think that the upper mass' momentum coupled with inertia and the fact that below it is a rock solid 70+ floors of undamaged building with 47 core columns, floors and steel outer columns... would propel it off to the side of the building (where there is no resistance) instead of down and through a structure which had the ability to support (massive resistance) the weight of the upper mass?
The "path of least resistance" is an incremental thing, with the possible and sometime exception of
superfluids. At all times the total energy gradient has to be negative. Ordinarily, the trajectory of an object cannot ever actually reach the true path of least resistance. In some cases, that path is not even an
attractor.
Here's a dumb example. Let's say your house is on a small hill, with nothing around it. An 18-wheeler is heading straight for it at high speed. Will the 18-wheeler magically flow around your house, damaging nothing? That's the path of least resistance, right?
Wrong. The "resistance" also includes the energy needed to alter the truck's vector. It's actually harder for it to miss than it is to smack your house. Your insistence that the upper block would somehow slide to the side assumes that it would take
no energy at all to slide the block 200 feet so that it could drop.
Guess what: Moving a 50 thousand ton block 200 feet sideways takes
lots of energy. This has been explained to you at least ten times, including graphically. Aside from a puppet show, I don't know what else to try.
Yea, the WTC 1 & 2 fell because of the way the upper mass' latent energy penetrated the towers' terminal resistance threshold. Are you that dumb... please go read a book and learn something.
Ah, so the proven
liar and
slanderer claims to be more knowledgeable than us, huh?
Let's test that theory:
I have the same question... what magical lateral force, caused the upper mass (supported by 37 non-severed vertical core columns) to tilt over?
That's okay... because all of the thousands of first hand accounts (including firefighters and policemen) of hearing explosions going off... has been debunked as exploding cans of hair spray.. the Towers were only a few miles from Jersey, weren't they?
So let's suppose your idiotic observation was correct: It was explosives that shoved that 50 thousand ton block 200 feet to the side.
Suppose the block is blasted in a parabolic arc, moving 200 feet aside in roughly one second, but feel free to use whatever time you wish. Also suppose the explosives are 100% efficient in doing this (there's no way in the world they would -- explosives are really, really bad at moving solid objects -- but let's make this as easy as possible).
1. Numerical answer: How much explosives are needed? Show your work.
2. Essay answer: Is there a way to tell whether an explosive this size was detonated?
Let's see what you've got, since you've "read a book" and "learned something." I'll be glad to check your work, since I can calculate this standing on my head.
