Dyson spheres

A Dyson sphere is a hypothetical structure proposed by physicist Freeman Dyson in 1960. It's designed to capture energy from a star, like our Sun, to power advanced civilizations. Instead of a solid shell, which is impractical, it often refers to a swarm of satellites or solar panels orbiting the star, collecting energy. This concept reflects the idea of an advanced civilization’s ability to harness enormous amounts of energy, potentially leading to significant technological advancements. Dyson spheres highlight how civilizations might evolve as they seek to meet their growing energy needs.
