The physics of 9/11 -- including how fast and symmetrically one of the World Trade Center buildings fell -- prove that official explanations of the collapses are wrong, says a Brigham Young University physics professor. Professor Steven E. Jones recently submitted an academic study of the 9/11 attacks, which reveals a frightening picture of what happened. Using simple laws of physics and engineering he shows how each of the collapsing towers could not have fallen as a result of fires burning in
