Discuss the below:
Q1: Write about and describe the processes that occurred in the universe between 10^(-11)s and 10s after the Big Bang which gave rise to matter in the form of Protons, Neutrons and Electrons.
Q2: Explain the significance of the mass energy of particles in governing the reactions that could take place as the mean energy per particle available in the Universe decreased. In addition to this suggest reasons why matter may have come to dominate in the Universe as we know it today.
Dominance of matter in the universe rather than anti matter gives the Universe its structure as we know it today. However 10^(-11)s after the big bang the universe would have consisted of approximately equal number of particles and antiparticles.
