Researchers Propose Ancient Origins for Pleiades Myths, Suggesting 100,000-Year-Old Story

Researchers Propose Ancient Origins for Pleiades Myths, Suggesting 100,000-Year-Old Story

A new hypothesis suggests that the myths surrounding the Pleiades star cluster, known as the 'Seven Sisters,' may date back 100,000 years. Researchers Ray and Barnaby Norris used data from the Gaia space telescope to simulate the appearance of the Pleiades to early Homo sapiens. They found that two stars, Atlas and Pleione, which are now indistinguishable to the naked eye, were once separated by a larger angular distance, making them visible as distinct stars. This could explain why many cultures have similar myths about the Pleiades, as they might have originated when the stars were visibly separate. The researchers argue that the story has been passed down through generations, potentially surviving for 4,000 generations, challenging previous assumptions about the longevity of oral traditions.

Harvard Astrophysicist Suggests Interstellar Object 3I/ATLAS Could Be Alien Craft

Harvard Astrophysicist Suggests Interstellar Object 3I/ATLAS Could Be Alien Craft

Astrophysicist Avi Loeb from Harvard University has proposed that the interstellar object 3I/ATLAS, which recently entered our solar system, might be an alien spacecraft. This suggestion is part of a thought experiment that Loeb and his colleagues conducted, inspired by the 'dark forest hypothesis,' which posits that extraterrestrial civilizations might be hiding from each other. The object, which is unusually bright for its size and exhibits a retrograde orbit, has sparked interest due to its peculiar characteristics. Despite the hypothesis, Loeb acknowledges that the most likely explanation is that 3I/ATLAS is a natural interstellar object, possibly a comet. However, he argues that examining such objects with an open mind could yield insights applicable to future interstellar discoveries.
