Conspiracy theories about the moon landings in the 1970s claimed that the Apollo program was a hoax. Some of the main arguments of the conspiracy theories were:1. Van Allen radiation belts: It was claimed that radiation in these belts would be lethal to the crew. However, today's manned satellites fly under these belts, and so it would not be an impediment to a flight to the moon.2. American Flag on the Moon. In reality, there is a vacuum on the moon, which is why the flag behaves differently than on Earth.3. The astronauts' footprints were sharp, leading to the assumption that they were made by studio lights. In reality, the footprints on the Moon are caused by uneven terrain.4. Shadows in photos: Some photos showed varying shadows, leading to the assumption that they were created by studio lights. In reality, the shadows on the moon are caused by uneven terrain.5. Invisible stars. This is due to the camera exposure and the brightness of the moon's surface.However, these theories have been disproven in several ways. The Soviet Union monitored all Apollo missions and tracked them with radar and other devices. The rock samples brought back from the Moon contain traces of long-term exposure to solar wind and micrometeorite impacts, which would be difficult to replicate artificially. In addition, the popular science series Mythbusters has conducted experiments that have confirmed the authenticity of lunar missions, including simulating small moon gravity. So the moon landing was real and not a hoax.
