The main thing that bothers me about "3 Body Problem" so far is the suggestion that if lots of science experiments started having weird results suddenly, physicists would be all "well, science is broken, might as well pack it in", as opposed to "whoa, this is amazing, we need more funding to study this phenomenon!".
Well, okay, and that a strong gravitational source would not PULL EVERYTHING UP OFF OF THE PLANET'S SURFACE, because the planet would be pulled just as hard as the things, sheesh.
