I have been following this device for a while. The construction alone was just incredible. The breakdown that took place in September is going to delay things until next year. That sucks.
The hope is that they find the Higgs Boson
That and a few other things. As with science though when you answer one question it raises many more. So it will be very interesting to see some of the other research that is done.
And then there are the crackpots. http://www.dailygalaxy.com/my_weblog/2008/09/doomsday-black.html Daily Galaxy favorite Walter Wagner has finally been thrown out of court! For those of you who don't subscribe to Nutjob Monthly, Mr Wagner has been filing lawsuits to prevent the activation of the Large Hadron Collider - mainly based on the assumption that his time working in a hospital with nuclear medicine and a Hawaiian botanical garden gives him a better understanding of particle physics than almost every scientist on the planet. It turns out this wasn't a great assumption.
As jerrymac said this is a bunch of adults getting together and smashing stuff. It goes to show that even with an Ivy league education and a Phd. That when we smashed stuff as kids it was fun. And we will find new ways to smash things when we get older.
For me I also love this stuff because it causes the creationist to get their panties in a bunch.
