Nibiru

Nibiru is a hypothetical planet sometimes associated with doomsday conspiracy theories, suggesting it will collide with or closely pass Earth, causing catastrophic events. There is no credible scientific evidence supporting Nibiru's existence or any such impact. Astronomers and space agencies have found no signs of this object, and many experts consider it a modern myth or hoax. The idea often originates from misinterpretations of Ancient Mesopotamian texts or pseudoscience, but mainstream science regards Nibiru as unsubstantiated and not a real celestial body.
