If the Higgs Field could exist with constant 246GeV across all of space. How come the Dirac Sea couldn't exist? If the Universe can easily accommodate Higgs Field.. why not Dirac Sea for all particles. Also how does the Dirac Sea of bosons work? Like W+, W-? Any idea? I was asking about the classical Dirac Sea. For modern Dirac Sea, there seems to be a revival https://en.wikipedia.org/wiki/Dirac_sea "Dirac's original concept of a sea of particles was revived in the theory of causal fermion systems, a recent proposal for a unified physical theory. In this approach, the problems of the infinite vacuum energy and infinite charge density of the Dirac sea disappear because these divergences drop out of the physical equations formulated via the causal action principle. These equations do not require a preexisting space-time, making it possible to realize the concept that space-time and all structures therein arise as a result of the collective interaction of the sea states with each other and with the additional particles and "holes" in the sea." What is the consensus of the experts? Is there no possibility for Dirac's original concept to be viable? How about Causal Fermion Systems? What do you think of it? What flaws can you see here that can bury the whole (old and modern idea of) Dirac Sea for good?
