This dream,
called the Grand Unified Theory, would give us a simpler, more elegant understanding of the universe, showing that all the interactions we see are different manifestations of one unified force.
In their paper, «Higgs Seesaw Mechanism as a Source for Dark Energy,» Krauss and Dent explore how a possible small coupling between the Higgs particle, and possible new particles likely to be associated with what is conventionally
called the
Grand Unified Scale — a scale perhaps 16 orders of magnitude smaller than the size of a proton, at which the three known non-gravitational forces in nature might converge into a single
theory — could result in the existence of another background field in nature in addition to the Higgs field, which would contribute an energy density to empty space of precisely the correct scale to correspond to the observed energy density.
