The term "9/11 conspiracy theories" refers to various beliefs that challenge the official account of the events surrounding the terrorist attacks on September 11, 2001. Some theorists argue that the U.S. government had prior knowledge of the attacks or was involved in orchestrating them, while others question the collapse of the World Trade Center buildings, suggesting controlled demolition rather than the impact of the hijacked airplanes. These theories gained traction due to perceived inconsistencies in the official narrative and the emotional impact of the attacks. Despite extensive investigations, including the 9/11 Commission Report, many conspiracy theories persist, fueled by distrust in government and media sources.
