World Trade Center Conspiracy Theories: Claims and Debunking

Numerous conspiracy theories challenge the official account of the Twin Towers' collapse on 9/11. The major narratives include:

1. Controlled Demolition: Asserts the towers fell symmetrically at free-fall speed due to pre-planted explosives, citing molten metal and collapse dynamics.
2. Thermite/Nanothermite: Claims incendiary compounds cut steel columns; proponents point to alleged residue in dust samples.
3. Directed Energy Weapons: Suggests space-based lasers or particle beams "dustified" the towers, citing odd light phenomena.
4. Mini-Nukes: Posits small nuclear devices caused vaporization and radiation traces.
5. Total Hoax: Argues the attacks were staged with CGI, no planes, and physics-defying collapses.

Scientific Consensus: Extensive investigations by NIST, FEMA, and independent engineers confirm the collapses resulted from airplane impacts and ensuing fires weakening structural steel. All alternative theories have been thoroughly debunked; no credible evidence supports them.
