On a Macroscopic Scale, Space–Time Symmetry makes Particle's Universe the Same as Anti– Particle’s Universe, Whereas Particles on a Microscopic Scale, Charge Symmetry Makes Atom and Anti–Atom the Same

Every particle has a counterpart - an anti-particle. When any amount of anti-particle comes into contact with a particle, it will annihilate itself and produce energy in a flash. The space-time symmetry is what makes a particle's Universe exactly the same as anti – particle’s Universe. On a macroscopic scale, both Universe pairs appear to be same. On a microscopic scale, the charge symmetry is what makes an atom and its anti-atom equal. Only observer dependent realism exists for the Universe and Atom pairs. An observer made of particle will view the exact opposite of an observer built of anti-particle – the observer pair will view the exact opposite reality, rendering reality relative. In this chapter, I'll talk about space-time symmetry on a macroscopic scale and charge symmetry on a microscopic scale.
