The big bang theory

This is something interesting that i have learnt during lesson today. So thought to share with u gus :)

The big bang theory : creation of galaxy and universe

Our galaxy/ milky way/ universe started from a point of compressed mass, high density, high energy and high temperature. The energy was so large that it could no longer be contained in that point and so it expanded (the big bang theory). As it expands, temperature decrease and this resulted in the existence of quarks. Quarks is the simplest makeup of anything. temperature continued to decrease and this allows the quarks to have the ability to combine and form neutrons and protons. Neutrons and protons then combine to form nucleus and then atoms and basic element, such as hydrogen. Which eventually leads to the deveopment of matter (which consists of many many atoms)

Although scientists have spent many years discovering this and it seems rather logical, scientists were unable to explain what happened before the big bang or what was in the universe before the big bang. Till today, this remains a mystery to many. From the big bang theory, we can see how systematic the formation of the universe was. Although the energy informed was so great, one incident led to another and one formation led to another. (There ought to be something bigger that is determining all these). If the big bang/ formatiom of the galaxy was mere randomness, under such high energy and temperature, things would have gone really wrong. Take for example nuclear fission.

From the big bang theory, we can see that the creation of the universe is very physical, consisting of quarks and mere 'dead' atoms. Bacteria, fungi, plants, animals and especially man who have life in them can never be created from the universe itself which is a makeup from energy and quarks. Especially man who has the essence of being in them and has feelings, thoughts, emotions and intelligence. How could man being so unique and personal be created out of the physical galaxy of energy and quarks?
