I knew you were going to reference those; however there is a stark difference with those conspiracy theories. They were all theories AFTER the fact, and they were all being investigated on a journalistic level. They weren't just random people making stuff up that later proved to be true.
Sometimes absolutes work, as they are so close to the truth you can call it fact. For instance, it maybe possible for the sun to suddenly quantum tunnel to another part of the galaxy. However I can confidently say, that will never happen; sure it might do, but it's such an infinitesimally small chance, I'm going to say never.
