Or we're seeing one fall apart.
(I still think that Dyson spheres are an idiotic thing to build. If you're worried about getting energy for your civilization, and you can do stellar-scale engineering, there are better things to do with a star's mass than let it waste its fuel in a big, uncontrolled trash fire, collecting it with solar cells or whatever).

- drjesusphd 10y agoNuclear fusion is the most energy dense process in the universe. If the reaction is already going, why mess with it?
- blackflame7000 10y agoActually, antimatter-matter annihilation is about 500 times more energy efficient.
- kabdib 10y agoNot really; the energy density in the core of our sun is about 100 watts / cubic meter. (Energy density is a LOT higher in more spectacular events, like supernova and the first few milliseconds of a hydrogen bomb's fun-time). Smaller stars burn fuel more efficiently. Our sun is good for about 4-6 billion years; a much smaller star will last several trillion years.
