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.

    Well unless they are monitoring or are relatively close. The issue was they got annoyed cause their decedendants won’t see their “holy constellation”. Something like a north star to them I guess. So anyway I started a purification campaign In response.

      …no, they won’t know for a few hundred years due to the actual speed of light and vast distances of space.

        Unless they have some fancy alien sensor with quantum entangled particles so they get an alert instantly

        It’s a Stellaris reference. Once you can build Dyson spheres there’s a chance your (also FTL capable) neighbors complain about you blocking their sacred star.

        I usually just give them money and they forgive me.
