Panspermia is a scientific hypothesis that suggests that life on Earth and potentially other planets was seeded by microscopic life forms, such as bacteria or spores, that were transported through space. This transfer could occur via comets, asteroids, or interstellar dust, enabling these life forms to survive the harsh conditions of space and eventually reach a suitable environment where they could thrive. The concept challenges the idea of life arising independently on Earth and posits that life may be more widespread in the universe, with the potential for organisms to evolve on various celestial bodies. Panspermia is often explored in the context of astrobiology and the search for extraterrestrial life.
Scientists have long been fascinated by the concept of panspermia, which suggests that life's building blocks can travel between different areas of space, leading to the existence of extraterrestrial life…
