"Loose Change" is a documentary film that explores various conspiracy theories surrounding the events of the September 11 attacks in 2001. It presents claims that the official narrative of the attacks is flawed and suggests alternative explanations, including the idea that the U.S. government had prior knowledge of the attacks or was involved in orchestrating them. The film gained significant attention and sparked debate, leading to discussions about media influence, government transparency, and public perception of major events. While it has been criticized for its lack of credible evidence, "Loose Change" remains a notable example of how conspiracy theories can capture public interest and provoke critical thinking about historical events.
