The idea has been proposed in a different branding as the Great Filter (en.wikipedia/Great_Filter). There are also other explanations as well. Maybe we're just all simulated (in an ancestral simulation). Stars and intergalactic systems are just too cumbersome to simulate all, so maybe whoever programmed us just threw their hands in the air and said "fuck it," and then make them really darn far and unreachable. It would be an entertaining thought to me at least, as a lazy programmer. Here is your 1 mile 3d viewport, anything further than that is not actually 3d but 2d bitmaps with some clever hacks that make them look like 3d to you. Fuck it, let's go bowling.
