The correct answer will resolve to the earliest date. For example if a human build a Dyson Sphere in 2040 then the correct answer is 2050.
Never means that building a Dyson Sphere will never happen. If the date is January 1, 2200 and a Dyson sphere was not built the resolution will be Never.
Resolution Criteria:
Energy Capture threshold:
The structure must capture and utilize at least 1% of the Sun's total energy output.
Official measurements from at least 3 independent space agencies confirm the energy capture threshold has been reached.
Specifications:
The structure(s) can be of any design: Dyson Sphere, Dyson Swarm, etc
Human Civilization Control:
The structure has to be built by humans or artificial intelligence originating from earth, or a cooperation between both. Discovery of Dyson sphere built by Extraterrestrial aliens does not count.
