Self-replicating probes are theoretical spacecraft designed to explore distant regions of space by creating copies of themselves. These probes would use local materials to build new units, allowing them to cover vast distances and gather data without the need for constant human intervention. The concept is inspired by biological processes, where organisms reproduce to ensure survival and adaptation. By utilizing advanced technologies, such as nanotechnology and robotics, self-replicating probes could potentially explore planets, moons, and asteroids, significantly expanding our understanding of the universe.
