Baryogenisis Vs Newton's Theory

Issacc Newton’s third law of motion states that for every action there is an equal and opposite reaction. Antimatter is essentially exactly what it says on the packet, it is the opposite of matter. Well, more accurately all of antimatter’s properties match those of matter, except with an opposite charge. For example, antiprotons have a negative charge, and antielectrons(often called positrons) have a positive charge. Antimatter can form atoms and molecules just like matter, however the charges remain opposite. At the formation of the universe equal pairs of matter and antimatter were formed out of energy. This is supported by Einstein’s famous equation: e=mc^2. However the equation works both ways, and because of their opposing nature, when …show more content…

This theory focuses on baryons, which are particles made of three quarks, like protons and neutrons. There are two differing theories within Baryogenisis. The first is that the asymmetry of baryons and antibaryons was present from the beginning of the universe, but current theories of inflation dispel this theory as excess matter would be diluted, or the asymmetry was caused by an unknown mechanism. According to nuclear physicist Andrei Sakharov, the existence of this mechanism requires three conditions: C and CP violation, Baryon Number violation and Thermodynamic Nonequilibrium. Cronin and Fitch proved the existence of C and CP Violation, but what about baryon number violation? Basically baryons (made of 3 quarks) are assigned a baryon number of 1, and this net number is conserved in all natural processes. However proton decay, which has never been observed, theoretically produces positrons and neutral pions which doesn’t conserve the baryon number as both have are assigned 0. Finally, the mechanism theoretically occurred before thermodynamic equilibrium, allowing the universe to cool at different rates and prevent symmetry from reemerging. This theory is promising but contains many unobserved factors. However the Standard Model, a 1970 theory stating all know fundamental particles and how they react, theoretically meets all three conditions. Assuming these conditions are met, there are two main theories suggesting Baryogenesis occurred at either 10^-43 or 10^-12 seconds after the Big Bang. Baryogenesis is therefore more promising than CP violation, but more investigation into the physical mechanism would create a more plausible
