... The LHC is an example of a synchrotron. It accelerates protons to 99.9999% of the speed of light, colliding them at high energies and recording the results on huge computers. But what is the LHC looking for? Is Science wrong? – If the LHC does not conclude any results as to the origin Extra Dimensio ...
