Some popular explanations of the Higgs boson go something like this: 'Without the Higgs, all the energy bits we call fundamental particles would be moving at the speed of light and could not interact with each other, nothing would 'happen'. The interaction with the Higgs field give those particle mass, slowing them down to sub-luminal speed and allowing them to interact in time.' Now, I presume that in a Universe where all particles moved at the speed of light, it would be rather meaningless to talk about Time (even if a Time dimension should exist for those particles to have any 'speed'). Nothing would 'happen' (or as someone said, everything would happen at once). From this point of view, could we say that the Higgs is the cause for Time being a discernible dimension in our Universe? I mean, our Universe might have a Time dimension intrinsically, but Time as we know it (i.e. 'the passage of Time') exists only because of the Higgs field and its interaction with leptons and quarks.
