The conspiracy theories about the September 11, 2001 attacks began circulating on the very day that two planes crashed into the Twin Towers, and 25 years later they continue to appear at dinners, on terraces and on social networks. These theories question the official version of events and propose alternative explanations about what really happened that day.
The so-called "Truth Movement" remains active through websites and self-managed forums such as the 9/11 Visibility Project and AttackOnAmerica. These channels continue to promote and disseminate their theories to new audiences, adapting to contemporary digital platforms.
The proponents of these theories claim that the US government is hiding information about the attacks so that the population accepts a more authoritarian regime. This narrative maintains that authorities would have an interest in manipulating public opinion through incomplete or falsified versions of events.
The theories have been consistently debunked by experts, engineers and official investigations over the past two and a half decades, but continue to find resonance in informal conversations and digital spaces where they circulate without verification.
