Dug shot an episode of "The Answers", at Fermilab, a national science laboratory of the Department of Energy's Office of Science. http://www.fnal.gov/. The machine in this photo looks like a surreal sci-fi movie set and is used to create protons. These protons are then destined to travel at the speed of light, through Fermilab's proton excellerator, a 3 mile circle. Look out! Dr. Who could drop in any moment with the Tardis.
