[QUOTE="Thomas Bowman, post: 7306990, member: 6925649"] How about something like the Matrix? A simulated world and then a real world, or how about a whole bunch of simulated worlds contained within the shell of a Dyson Sphere, and I know just the sort of star to build a Dyson Sphere around. Ever hear of Gamma Crux? It is the closest red giant star to our Sun, it is located in the constellation known as the "southern cross." [URL]https://en.wikipedia.org/wiki/Gamma_Crucis[/URL] This star has some pretty important properties that would make building a Dyson Sphere around it easier than building one around our own Sun. First thing is that it is 30% more massive than our Sun but 820 times as bright, that means that the habitable zone is much further out than our Sun, to find out how far out that would be, you take the square root of its luminosity 820, which is 28.6 times the distance of the Earth to the Sun A regular Dyson Sphere around our Sun would have a surface area equal to 500,000,000 Earths. Gamma crux can illuminate a sphere with 820 times that area at the same energy intensity as the surface of the Earth, the amount of area illuminated would be 410,000,000,000 times the surface area of the Earth, that number is also about the number of stars in our galaxy. You could simulate the inhabited portion of an entire galaxy, as you only have to simulate the parts where the people are! People within the simulation wouldn't know they are in a Dyson Sphere, they would have space ships and flit between stars, kind of like in Star Wars, and they would be none the wiser. To go outside, they would need android bodies. [/QUOTE]
