I saw this several nights ago. I have a new appreciation for old Star Trek episodes. If the universe is an infinite series of experiments then Dyson Spheres are probably a reality. This one is 200 million kilometers in diameter with the internal surface area equivalent to 250 million class M planets. Scotty/James Doohan was in this episode and crash landed on its surface. He locked himself and another crew member into a 75 year transporter cycle, so they could survive. Relics (Star Trek: The Next Generation) - Wikipedia www.youtube.com/watch?v=4TCg4vsAc&t=28s
