In this review article, a brief history is given about how the physicist's image of the universe is evolved and developed during centuries starting from the early civilization of mankind up till our present times. This is followed with a proposed model, by the author, for a dual anti-universe to ours and the possible experimental tests to verify and confirm its existence. The model suggests the presence of a primordial S- Particle that, following the ‘Big Bang', was violently ejected in all spatial directions together with its anti-particle. The hypothesized S-particle differentiates itself from its counterpart ‘anti-particle' through its course of rotation (the angular rotation of the S- S-particle is opposite to that of its counterpart). Both particles underwent two-phase transitions in space-time that led to the formation of the known fundamental particles “quarks, electrons, neutrinos...etc., and their anti-particles" and hence, evolving with time forming our universe and its dual anti-universe. The angular rotation of the anti-particle, in accordance with space-time rotation, together with the counter-rotation of the S- particle, resulted in a time difference in the formation processes of both universes and consequently led to a large distance between the spatial locations occupied by our universe and its dual counterpart in the same space-time continuum. The existence of this anti-matter universe might solve the present mystery of matter anti-matter asymmetry and thus explain why hardly any free anti-matter can be observed in our universe.
