For irrefragable physicochemical proof that the 9/11 attacks were an inside job by deep-state elements of the US government--i.e., via the use of large quantities of thermite in the case of the collapse of the three destroyed World Trade Center towers--see pp. 75-84 of my following article:

The foregoing article concerns physicist and mathematician Prof. Frank J. Tipler's Omega Point cosmology and the Feynman-DeWitt-Weinberg quantum gravity/Standard Model Theory of Everything (TOE), which is a proof (i.e., mathematical theorem) of God's existence per the known laws of physics (viz., the Second Law of Thermodynamics, General Relativity, and Quantum Mechanics). Tipler's Omega Point cosmology has been extensively peer-reviewed and published in a number of the world's leading physics and science journals. However, it also analyzes the societal implications of said, particularly the implications of the exponential advancement of technology and hence also the coming radical life-extension technologies in light of a world dominated by a callous oligarchy.
