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

    Yeah never heard about it, although I never watched Star Trek personally.

    But did you know that we can extract Graphene by heating it up super high so that everything else gets destroyed except graphene?

      Eh, there’s only one in all of Star Trek, and they forgot about it after one episode. Should have a whole series.

        There was a star trek novel dealing with it. I read it but don’t remember any details. My favorite along those lines was the ringworld books.

      I don’t think it’s surprising at all that you’ve never heard of a Dyson sphere. It’s not a very popular idea even in science fiction.
