Dyson Sphere
Hypothetical megastructure proposed by physicist Freeman Dyson in 1960. It consists of a collection of orbiting structures or a shell surrounding a star to capture and utilize its energy output. Such a structure would enable an advanced civilization to harness nearly all of the star's energy for their technological needs.
The Goldilocks Zone, also known as the habitable zone, refers to the region around a star where conditions are "just right" for liquid water to exist on the surface of a planet, which is considered essential for supporting life as we know it. The term draws from the "Goldilocks" fairy tale, where things must be neither too hot nor too cold but just right.
Traveling to distances measured in light-years presents immense challenges due to the vast scale of space and the limits of current technology. A light-year is the distance light travels in one year, approximately 9.46 trillion kilometers (5.88 trillion miles).
