Part 4/7:
One of the critical issues raised in this discussion is the manner in which each tower fell—essentially in free fall. This phenomenon raises significant questions about physical laws, particularly the law of conservation of momentum and energy. If the towers were indeed subjected to the gravitational pull unimpeded, this would contradict the expected deceleration due to the mass of the lower structure.
Such evidence provides a launching point for broader discussions about the validity of explanations for the buildings' collapse, especially the now-discredited “pancake theory.” For years, the pancake theory was touted as the probable cause of the collapses, yet recent investigations and tests have rendered this explanation obsolete.
