are you using an example of controlled demolition in order to refute the controlled demolition theory??
Oh Jesus...
You, TakeAStepBack, and others think that the upper section of the tower could not shear/demolish the lower section of the tower with gravity alone. This is based on:
Kinetic energy can't be used for two separate works. So it either expelled that energy as it sheered off (meaning that the total mass of the upper section became smaller, along with its potential/kinetic energy along the way), or it used it to pulverize the section below it. One or the other, not both. You would need an energy input for that to occur and we dont have one. Unless you know something we dont.
So I asked that you explain, based on TakeAStepBack's explanation above, how the building in the verinage video I posted goes against TakeAStepBack's "understanding" of the laws of physics.
