A Dyson sphere is a hypothetical megastructure that completely encompasses a star and captures a large percentage of its power output. The concept is a thought experiment that attempts to explain how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet's resources alone. Only a tiny fraction of a star's energy emissions reach the surface of any orbiting planet. Building structures encircling a star would enable a civilization to harvest far more energy.

The Cajuns, also known as Acadians, are an ethnic group mainly living in the U.S. state of Louisiana, and in the Canadian maritimes provinces as well as Quebec consisting in part of the descendants of the original Acadian exiles—French-speakers from Acadia (L'Acadie) in what are now the Maritimes of Eastern Canada. In Louisiana, Acadian and Cajun are often used as broad cultural terms without reference to actual descent from the deported Acadians. Historically, Louisianians of Acadian descent were also considered to be Louisiana Creoles, although Cajun and Creole are often portrayed as separate identities today.
