One must wonder the kind of mentality required of someone in order to support a comparison between pizza boxes, sponges, & lemons to full-sized buildings. But fear not, you've earned my respect for having the balls to support such comparisons -- you see... not everyone is able to support that level of idiocy with such honesty
I commend you.
I think this question is relevant enough, I asked this very question to two other members, but I fear they won't demonstrate the intellectual honesty of genuinely answering it. Perhaps you could?
By assigning proportions (percentages, relative size, etc) to the upper section in order to state that a smaller part is incapable of crushing the larger, are you implying that the force of an object in motion when it encounters a sudden change in acceleration is the same as when the object is at rest? In other words if I can carry 100 pounds at rest, does this mean that I can carry the same mass falling into my arms from 10 feet?
Any conspiracy theorist is welcome to tackle this.... I'm afraid until you understand that the size is to an extent less important than the force the mass imparts when it accelerates that any "competition" with you would be worthless
