Antimatter and the Possibility of a Parallel Universe: Exploring the Genesis and Existence of an Antimatter Universe

Abstract

Antimatter, the oppositely charged counterpart of matter, has been extensively studied in physics. Although matter and antimatter were produced in roughly equal amounts during the Big Bang, our observable universe appears dominated by matter. This paper investigates the possibility of a separate, spatially and temporally mirrored antimatter universe. This study employs CPT symmetry and gamma-ray observations to assess the plausibility of such a universe existing beyond our observable limits, offering insights into fundamental symmetries and cosmic evolution.
