Eventually humans will have to leave this planet and find a home planet elsewhere. It may not happen in anybody alive's lifetime, but it will happen if we expect to make it as a species. The research done by the Large Hadron Collider is prepping for the inevitable. It is able to look into galaxies and understand potential liveable planets in places we didn't even know existed 10 or 15 years ago.
I believe society is benefiting from the research completed at the Large Hadron Collider. This device is helping scientists answer new questions about how our world and the universe operates. We are getting hard evidence that we were not able to compile prior to this device being created. I believe society will reap even more benefits in the future.
To be honest, the research and revelations coming from the Large Hadron Collider will never be understood by the vast majority of people. The information is too abstract and scientific. It will still come to their benefit too. Learning about how mass and energy is made will certainly lead to advancements in other fields that will be more tangible to non-scientists. Cheaper energy, stronger materials, and a cleaner world are all potential innovations that might start from the research done at the LHC.
Although Large Hadron collider provides widening of knowledge, Knowledge itself is seldom used for destruction. 50 years of research in Atomic theory yielded us Nuclear bomb and then after moderation, Nuclear Energy. Large Hadron Collider is an ambitious and beautiful project but has huge chance of 'misuse' by mankind's own greed, judging by our history.
No, society is not benefiting from the research completed at the Large Hadron Collider, because the research is very expensive. We have put so much money and effort into the Hadron Collider, to have very few results that are in any way practical to our lives. It is just fun for the people who are doing it.
