Missing antimatter at the time of big bang formed the small windows (fermions) connecting our 3-D physical universe to the 5-D Hyperspace
Equal amounts of matter and antimatter were created at the big bang. Why is there only matter left around? Why didn''t all the matter and antimatter meet up and annihilate, leaving a universe without matter?
As a matter of fact, shortly after the big bang, most of the matter and antimatter did annihilate, but one in a billion particles survived and that became the galaxies, the universe, and us as we know it now. Still why even one in billion particles survived if there were equal matter and antimatter?
The answer lies at least partially in an effect called charge parity (CP) violation that indicates matter and antimatter decay differently. But still that does not provide the whole answer why some matter were left behind and the antimatter are all gone! Particle physicists are baffled to answer that question.
In experiments conducted at the particle colliders scientists were able to partially determine the differences in decay between elementary particles and antiparticles.
But the degree of CP violation determined by these experiments—and others—fails to account for the entire matter-antimatter imbalance in the universe
Scientists now are finding clues to the entire matter-antimatter imbalance in the universe. What really happened is that during the big bang some antimatter formed the small windows (fermions) linking the 3-D Physical Universe with the 5-D Hyperspace. These fermions, balckholes and the neutron stars linking our physical universe (3-D Space) with the 5-D Hyperspace provide the necessary openings through which the Hyperspace provides suction. This suction from Hyperspace is known as gravity and electromagnetic fields all around the physical Universe.
Some anti-meter formed the fermions or less than a particle size windows interfacing the Physical Universe and the Hyperspace. That created a matter-antimatter imbalance in the universe. As a result some matter survived and formed the galaxies, stars, planets and so on.
At the big bang the matter-antimatter imbalance and the resulting nature of matter present in a universe actually determines its dimensions.
