    If humans want to expand into space, it will take us incredible amounts of energy. How do we do that? Easy: we will just use the sun’s energy by realizing the most ambitious construction project in history. This is how it works.

      Did you see what that type X civilization did with the magnetic fields of the black hole at the center of the milky way?

      I always thought Dyson Spheres were art project BS for advanced civilizations. If you are that advanced you can get energy better ways.

              "The things you care about are dumb, start colonizing space" isn't wrong but is also wrong. Not wrong because if you care about space, well then yeah. But wrong because if you *don't* care about space at all, well then, no.

                  The amount of materials it would take to build a dysons sphere, to enclose a FRIGGIN STAR... is flat mind boggling. To even encase the Earth would be a ridiculous feat of engineering

                                  This can never happen. It will require unity as a species and intelligent people in power who can understand science and importance of this kind of mission.

                                  But politicians of earth is corrupted and they only focused about filthy short time goal and unity as a species is impossible because most of the humans are idiot and don't understand science.

                                        We really don't have enough energy, and if we were to continue at this rate we would eventually go extinct.

                                            Extraterrestrials do not use fueled rockets as we do to launch huge structures into the space. Instead, by using the unified fields they achieve the inertia reduction to put such giant structures into the orbit.
