Uhm, I'm a physicist by education and I like The Core. I see it as action-comedy that is played with a straight face. Of course it's all nonsense! It's not insulting if you never think you were supposed to take it seriously. The "unobtainium", the talk about money and timeline to build the ship (to anyone who has done anything remotely similar) and the uber cliche (and very funny) hacker type should be obvious clues.
