I can't wait to hear frustration of not finding the gravitons.
To see what I mean, here's some useful info I found compacted into 3 short clips (well you'll need an hour to spare)

Now is the hadron collider worth it? Large Hadron Collider nearly ready - The Big Picture - Boston.com
I mean, it uses up more energy during one simulation than it does to power Toronto in a day. And it has to be kept at a very low temperature, making it the largest cyrogenic facility in the world, or whatever its called. Not very environmentally friendly, and for the value of finding a couple particles... seems pointless.
But I believe there will be practical uses for the discoveries that the scientists are bound to make in the future with this. We harnessed the power of the electromagnetic force quite nicely with particle physics, and literally for use in making this collider. And the electroweak force was harnessed, requiring insights to the intermolecular world.
The whole purpose of this is to see if physicists are on the right track with their equations, because string theory has absolutely no evidence to support it, other than mathematical interpretations.
