This is a joke, right, well probably not. I always thought that a Dyson sphere was Gene Rodenberry's idea, but seems there has been some serious thoughts about it. BTW if there were any Dyson spheres out there, should we not be able to detect them already in a certain distance? I mean would that not cause some anomalies between emissions and gravitational behavior of the neighboring stars? Or is this shadowed by the gravitational overkill of the "central black hole"?

Ne rassemble pas des hommes pour aller chercher du bois, préparer des outils, répartir les tâches, alléger le travail… mais enseigne aux gens la nostalgie de l’infini de la mer. If you want to build a ship, don’t herd people together to collect wood and don’t assign them tasks and work, but rather teach them to long for the endless immensity of the sea. -- Antoine de Saint-Exupéry
