The Large Hadron Collider (LHC) is the world's largest and most powerful particle collider, the most complex experimental facility ever built, and the largest single machine in the world.[1] It was built by the European Organization for Nuclear Research (CERN) between 1998 and 2008 in collaboration with over 10,000 scientists and engineers from over 100 countries, as well as hundreds of universities and laboratories.[2] It lies in a tunnel 27 kilometres (17 mi) in circumference, as deep as 175 metres (574 ft) beneath the France–Switzerland border near Geneva.
How would they move a huge ring under the earth xD
I do not know. But I think it is in Austria now.
It is pretty hard to move that thing ;)
I guess I was just confused. It does seems permanent.
