A recent video shared by an astronaut on TikTok aims to debunk the long-standing “flat Earth” theory once and for all. In the clip, the astronaut waves to the camera before flipping it around to show a clear view of the Earth from space, demonstrating its spherical shape. This visual evidence, which has been widely shared on social media, counters the flat Earth belief, which some conspiracy theorists continue to promote despite centuries of scientific evidence proving the planet’s roundness.
The video was posted by the TikTok account @spacemanedu, which regularly shares footage taken by astronauts in space. The clip, captioned “Someone said Earth was flat,” has reignited discussions about the flat Earth theory and why such beliefs persist in modern times. Some experts, like astrophysicist Paul M. Sutter, suggest that the ongoing belief in a flat Earth stems from a general distrust of scientific authority rather than a lack of evidence.
Historically, the flat Earth theory dates back to the 19th century when figures like Samuel Rowbotham proposed ideas of a flat disc-shaped Earth centered around the North Pole. Today, the theory is kept alive by a small group of believers who often claim that images and videos from space are doctored or fake. NASA and other space agencies regularly release images and videos showing Earth’s curvature to counter these claims.
The continued sharing of such visual evidence aims to dispel myths and build trust in science and experts, encouraging more people to rely on verified information rather than conspiracy theories.
