# Have we observed magnetic monopole already? If not, why?

Please see 'here' for the energy scale of a (topological) magnetic monopole. It is around 11 TeV and I am impressed that the LHC reaches the scale of 14TeV already. Then have we observed the monopole already? If not, why?

• Probably because they don't exist, I guess. – flippiefanus Oct 14 '16 at 12:59
• Seems like too much of a simplistic and presumptive statement to bluntly say "the mass of the magnetic monopole is $M_W/\alpha$" – dukwon Oct 15 '16 at 0:49
• We know that without magnetic monopoles there would be no limit on the strength of magnetic fields in vacuum see eq. 8 of this paper, which is unphysical. For me that's good enough to say that we've observed the magnetic monopole, because "observation" is ultimately information extracted from Nature via experiments. – Count Iblis Oct 15 '16 at 6:58
