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.

Please 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.

I know that the 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.

Solution Summary

This solution presents an easy-to-understand description of the processes that occurred in the universe between 10^(-11)s and 10s of the big bang. It describes the processes leading to the formation of protons, neutrons and electrons, explains why matter (and not anti-matter) has come to dominate the universe today. and also the significance of mass energy in governing the reactions that could take place as the mean energy per particle available in the Universe decreased.

QUESTION

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.i need roughly 1000 words

In this question i need to explain the significance of the mass energy of particles in governingthe reactions that could take place as the mean energy per particle available in the Universe decreased.
In addition to this i need to suggest reasons why matter may have come to dominate in the Universe as we know it today.

I know that the 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.

Thanks!!!:))

SOLUTION:
I think that to answer this question clearly and in a way to benefit you, I should explain any concepts I feel you may not be familiar with, if however you are already familiar with any of the concepts I explained, please ignore it and keep reading. All concepts I explained are really needed for proper understanding of this solution, and I have referred you to some websites for other related information that are not really necessary here.
It will be necessary to start by stating that the big bang has remained the most successful of all theories that have been developed to explain the origin of the universe. It will also be necessary to explain the general rationale that this theory postulates (that is, that at the beginning, the universe was in a state of infinitely large density, infinitely large temperature, and infinitely small volume, and that it rapidly expanded thereby cooling down and dropping in density. Importantly today, most of the observations and measurements that are carried out by astronomers and scientists in various observatories and research centres prove the correctness of the big bang theory, one of them being that the universe is still expanding today as observed by the Hubble Space Telescope).
Now we go straight to address your question; that is what happened in the interval between 10-11s and 10s of the big bang (feel free to visit http://en.wikipedia.org/wiki/Big_Bang if you'll like to know what happened in other stages of the big bang, and how the big bang generally proceeded from one stage to another).
