s a hypothetical megastructure originally described by FreEman DYSON. such as 'sphere' would be a system of orbiting solar power sateliites meant to completely encompass a star and capture most or all of its energy output
By definition: a hypothetical mega structure originally described by Freeman Dyson In English: a giant shell of solar powered sattilites orbiting a star all linked together to capture almost all of its light energy and transfer it back to earth
I heard of this from watching Star Trek TNG. A Dyson sphere is a sphere or shield placed around the a planet and the star it orbits. This is so all the energy from that star will be absorbed by the planet, and none of that energy will be lost into space.
