A Dyson sphere is a hypothetical megastructure that encompasses a star and captures a large percentage of its power output. The concept is a thought experiment that attempts to imagine how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet’s resources alone. Because only a tiny fraction of a star’s energy emissions reaches the surface of any orbiting planet, building structures encircling a star would enable a civilization to harvest far more energy.

    A pinnacle of science, a wonder of engineering, that we will never get to see in our lifetimes. Instead, we get to see Taiwan get nuked or something, I don’t know. I don’t follow the news much, I only know I’m disappointed.
