Read this link, called "Beacons of discovers", written in autumn 2011. It is a committee report on the future of particle physics, written among others, by Alvarez-Gaumé and Pier Oddone.
Among the big questions of particle physics, the committee puts "the search for extra dimensions".
The committee does NOT ask: "what is the origin of the fine structure constant?" Feynman said that this was the greatest open problem of particle physics. But present particle physicists don not agree; they prefer to ask nonsense questions instead of the real questions.
Every single member of that committee should be fired from his or her present job.
