Similar kinds of questions were asked when people did "useless" research on trying to make smaller computers...Did I hit a nerve there... How will this help the Human Race?
Cars helped, the internet helped, modern medicine(of which going to the dentist these days is my fav) helped, agriculture helped, computers and the internet helped, renewable energy researched helps, understanding the weather patterns help......
How does better understanding the laws of nature and physics, better my life....
Please tell me, so I can try and one day reach a level of intelligence quotient, even remotely close to some of you, and feel good about myself and my Job I got because of that said aspect, and the Steak I am eating, while watching a documentary on the LHC....while our neighbours are starving!!!
One thing this discovery may do is prevent future useless experiments. Some string theories require particle colliders the size of our solar system. This discovery scrapped a few of those speculations as the standard model does not require such exotic interpretations
