Well.. games aren't meant to be overly realistic. Especially not science fiction games.. like space games (Destiny). Maybe.. it works the way you say it doesn't in the time frame that destiny is set in. There are things about physics that we currently don't know. Maybe instead of criticising the game.. you should play it and have fun doing so. Or play another more realistic game. If this really bothers you.. then games like Destiny aren't your type. Maybe CoD is.
