Dyson Sphere is a technology first constructed by Dr. Arya khan in 2562 around the star Groombridge 34. however, it was first proposed as an idea in 1937 by Olaf Stapledon and later popularized by Freeman Dyson in 1960.
A Dyson Sphere is a large spherical solar panel which completely envelopes a star. It is like a massive shell which blocks all stellar rays from escaping. They are typically several astronomical units away from the star so that they are not torn apart by the stellar wind of the star. Due to the impracticality of building an entire spherical mega-structure around a star, Dyson Swarms are used more often. A typical Dyson sphere produces about 7.6*10^19 joules of power every second.
