Another bad science moment that made me cringe was when they tried to explain how a couple of dots on a cave wall is actually a map to a specific point in the galaxy. Like, seriously? It was just a couple of dots on a cave wall. That's totally impossible. Why didn't they just say something like, "There is a very large mathematical number found in all of these ancient cave paintings, and there happens to be exactly one solar system at that light year distance from our own sun." That would seem at least remotely plausible to me, whereas, "These dots are a star map" seems absurdly ridiculous. It feels like they didn't consult any scientists at all when making the movie, which is really unfortunate.
