Everyone is talking about the risks of the LHC, but few have mentioned the potential rewards.
The experiment(s) is designed to further our understanding of the fundemental mechanics of the universe and the matter within it. There is a large gaping hole in our group of theories regarding matter and energy and the data retrieved from this experiment could fill that gap. The gap between planetary physics and atomic physics.
But why should we care Reactor Worker? :o ??
The answers we get from these experiments could lead to breakthroughs in anti-gravity and matter transportation technologies. It may also reveal new methods for creating sustainable super conductors.
They are not spending billions of dollars and "risking" billions of lives for nothing.
