On the possible connection between inertia and intrinsic angular momenta   and its consequences
  In this paper we show the consequences of a principle, according to which the dynamics of the Universe must not depend on the number of the particles of which it is composed. The validity of such a principle lead us to the conclusion that inertia and intrinsic angular momenta are deeply interrelated between them. In particular, assuming the principles outlined in the paper, matter must be composed by fermions, all stable bosons must be vectors and massless and no scalar particles can exist in the Universe. We also apply the results to the holographic principle and found established results more naturally with respect to previous approaches as well as new predictions about the Unruh effect.
