How do you build a massive experiment to experiment with the huge forces of the universe, whether dark or light, and then make sure people don't think much about it? This is something tha tmay have been done in the case of CERN, the large Hadron Collider in the center of Europe.
Plenty of mysterious stories floating around about it, and the statue of Shiva (the Goddess of Destruction) that was presented when CERN opened does hint at a darker purpose.
