Exoplanets May Be Connected by Hidden Biological Echoes

Main Idea

What if life on different exoplanets does not evolve completely separately? This theory suggests that habitable planets may exchange microscopic biological material through space over extremely long timescales. Asteroid impacts, comet fragments, and interstellar dust could carry dormant microbes or organic molecules from one planetary system to another. If true, alien life across different star systems may share a faint biological connection, like branches from the same cosmic tree.
