  • My first instinct would be that it would equivalent to putting another celestial body the mass of the earth at the distance from the earth is from each portal. Since gravity is a wave, it, in theory, would affect a region beyond what would considered “around” the portals.

    So if you put one portal on the ground, and another 100 meters up, it would be similar to there being a second earth 100 meters from the surface of the earth, experienced by the entire earth (once the gravitational wave propagated.) How that would evolve over time is too complex for my basic understanding of physics, but a simulation of it would be a neat experiment.











  • I’m sure there were other consoles that did it, but the one I remember is the NES; it had a physical switch on it for channel 3 or 4, and you had to have your TV tuned to the respective channel to get the game to show up. As to why that was necessary on a technical level, I’m not sure. But it was a thing you had to do.
