Explicitly invoking Newton's Third Law puts this result in another light. Since the forces in the interaction are equal and opposite, the falling block exerts a force of only 36% of its weight on the lower section of the building. In other words, as long as the falling block is accelerating downward we have the counter-intuitive result that the force it exerts on the lower section of the building is significantly less than its static weight. It is difficult to imagine how an upper block exerting a force of only 36% of its static weight could crush the larger, stronger, undamaged lower section of the building to the ground, when the building, at any level, was designed to support several times the weight above it. Assuming a safety factor of between 3 and 5 [12], the observed acceleration implies that close to 90% of the strength of the lower section of the building must have been eliminated by forces other than the supposed "pile driver," suggesting that some sort of controlled demolition was at work.

bredvid...Tror inte att upphovsmännen själva begriper eller tror på vad dom säger...
Om jag rätt förstår truthers så ligger det till så här:
WTC7 påstås ha fallit i fritt fall (eller nästan) under en tid. Detta anförs som ett bevis på sprängämnen eller annat foul play.
WTC1 påstås falla i 0.61*fritt fall. Detta anges också som bevis på sprängämnen eller annat foul play.
Man undrar: finns det någon fall-hastighet som ett hus kan falla med för att det skall vara "godkänt"?
Mästartiteln (den svenska alltså...) i ämnet "nutty physics" är väl vakant nu när Heiwa inte längre försvarar den.
Du har ju gjort ett "ryck" nu dom med senaste inläggen, men vi få väl vänta lite innan vi utser en ny mästare. Heiwa satte ju ribban högt...
Du har ju också mest citerat/länkat andras stolligheter.
Eget material ger mera cred!
