Are neutral Goldstone bosons initiating very energetic air showers and   anomalous multiple-core structure as a component of cosmic rays?
  We consider two recently accentuated, unusual empirical results concerning cosmic-ray events at high energies. We show that the possibility for a correlated explanation is provided by new dynamics which arises from collisions of a neutral Goldstone boson as a component of the highest-energy cosmic rays.
