What is the mass of the question mark?

    Newer Older

    Exhibit at the CERN visitor's center showing the different particle families (in this case the electron family). Masses are shown by 'size' - it is not clear whether this is by radius or volume. Even worse, the unknown mass of the neutrino, likely almost or exactly zero, is shown by a big question mark that looks heavier than all the other particles.

      Since the question mark, as I see it, is in photons, the mass is obviously zero.
