E = MC2 and WTC collapse

Why did the World Trade Towers seem to explode? Einstein's theory of energy and mass is above, e equals m csquared, or energy and mass can go either way. there is a finite amount of mass (and energy) in the universe. So when mass disintegrates it releases energy. How much mass does one tower of WTC contain? A scientist estimates that with a mass of about 500,000 tons (5 x 108 kilograms), a height of about 1,350 ft. (411 meters), and the acceleration of gravity at 9.8 meters per second 2, the potential energy is 1019 ergs (1012 Joules or 278 Megawatt-hours). "That's about 1 percent of the energy released by a small atomic bomb," the scientist noted.

The M.I.T. professor added that about 30 percent of the collapse energy was expended rupturing the materials of the building, while the rest was converted into the kinetic energy of the falling mass. The huge gray dust clouds that covered lower Manhattan after the collapse were probably formed when the concrete floors were pulverized in the fall and then jetted into the surrounding neighborhood. "Of the kinetic energy impacting the ground, only 0.1 percent was converted to seismic energy," he stated. "Each event created a (modest-sized) magnitude 2 earthquake, as monitored at Columbia University's Lamont-Doherty Observatory, which is located about 30 kilometers away from New York City." Kausel concluded that the "the largest share of the kinetic energy was converted to heat, material rupture and deformation of the ground below."

mass equals energy. the WTC became energy, and left over mass. That's why some believe in the conspiracy theories behind the WTC collapse: but its all about einsteins formula.
