.how did the mass increase when the concrete was pulverized and huge steel beams were sent flying outward ?were did the energy to do that come from in a free fall collapse ? ...if it happened as you say you would expect to see floors stacked like pancakes and the core remaining
Are you telling me that if I have a 10 ton slab of concrete and pulverize it, I no longer have ten tons?
Holy shit!
The mass increased because as the mass came down it gathered the mass of the other floors and components as each was destroyed.
