A Dyson sphere is a hypothetical megastructure that completely encompasses a star and captures a large percentage of its power output.
The concept is a thought experiment that attempts to explain how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's resources alone.
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.
You could take a Dyson Sphere and wrap around stars or even the sun, which yes is also a star.
Freemon Dyson is whom it's named after, he was a theoretical and mathematical physicist.
Dyson speculated that such structures would be the logical consequence of the escalating energy needs of a technological civilization and would be a necessity for its long-term survival. He proposed that searching for such structures could lead to the detection of advanced, intelligent extraterrestrial life. Different types of Dyson spheres and their energy-harvesting ability would correspond to levels of technological advancement on the Kardashev scale.
Imagine if humans made this!
