The Lorentzian interpretation of the special theory of relativity explains all the relativistic effects by true deformations of rods and clocks in absolute motion against a preferred reference system, and where Lorentz invariance is a dynamic symmetry with the Galilei group the more fundamental kinematic symmetry of nature. In an exactly nonrelativistic quantum field theory the particle number operator commutes with the Hamilton operator which permits to introduce negative besides positive masses as the fundamental constituents of matter. Assuming that space is densely filled with an equal number of positive and negative locally interacting Planck mass particles, with those of equal sign repelling and those of opposite sign attracting each other, all the particles except the Planck mass particles are quasiparticles of this positive-negative-mass Planck mass plasma. Very much as the Van der Waals forces is the residual short-range electromagnetic force holding condensed matter together, and the strong nuclear force the residual short range gluon force holding together nuclear matter, it is conjectured that the Higgs field is the residual short range gravitational force holding together pre-quark matter made up from large positive and negative masses of the order ±1013 GeV. This hypothesis supports a theory by Dehnen and Frommert who have shown that the Higgs field acts like a short range gravitational field, with a strength about 32 orders of magnitude larger than one would expect in the absence of the positive-negative pre-quark mass hypothesis.
