THIS FIELD has several unique characteristics: consistently non-zero value at all locations; imaginary mass; it is tachyonic (disappointingly, this does not actually imply or require the possibility of faster than light travel). Its boson is quite dull: no spin, no electric charge, no color charge. So boring, in fact, that excitations of this field (particles) are their own antiparticles. Strange, then, how much excitement (see what I did there?) was generated by the putative experimental observation of bosons of THIS FIELD. Well, maybe its generation of all hadronic mass makes it a *little* significant.
