I'm writing a silly Sci Fi short story about the development of various "simulated gravity" devices. It'll be a future-history type story (ala Heinlein), analysing as many devices as I can dream up beyond the centripetal force simulator, which is the most obvious and cheapest simulator to build.

Theory says that the universe will explode in perhaps a few million/billion years. People say its because, since the universe is expanding every second (Or so the people say,) there would be a limit. After the limit, everything explodes.

When do you think this would happen?
