A possible solution to the mystery of the ANITA anomalous events

Abstract

In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon-borne radio observatory flying over Antarctica, detected two strange upward-going radio pulse events that have not yet been explained by our current understanding of physics. These were not signals reflected by the ice and therefore it must have been an air shower originating from a cosmic ray coming from under the Antarctic ice, but this hypothesis was also ruled out by various data analyses. The CPT gravity theory and its associated cosmological model, the lattice Universe, can instead explain those events in a completely natural and spontaneous way, without any additional assumptions beyond general relativity and the expected matter-antimatter symmetry of the Universe on which they are based. Together with the antihelium candidate events from AMS-02, the anomalous ANITA events can thus lend further validity to a cosmological model that has already achieved considerable success in explaining the accelerated expansion of the Universe, without the need for dark energy. These events thus add to a series of problems unsolved by standard cosmology and physics, but whose solution is straightforward, spontaneous and natural within the framework of CPT gravity, without the need for ad hoc hypotheses and unknown ingredients.
