Explain the big bang theory as it relates to the atom and its evolution?
Answers
The big bang is the name that scientists use for the most common theory of the universe from the very early stages to the present day . The big bang theory is that the universe has not always existed. The early universe was hot and dense. As time passed the universe expanded,cooled and become less dense.
Great question! It let loose all the energy needed to form the very first atoms.
Explanation:
The short version of an otherwise very long explanation is that at the moment of the big bang there was nothing but energy. This is where Einstein's theory of special relativity comes into play
E=mc2
where E is energy, m is mass which is moving at the speed of light c.
Therefor, very very shortly after the big bang the universe went through an extremely fast expansion. It is estimated that the universe expanded in a matter of seconds, maybe less, to half the size it is today.
At that point, though very slowly, all the hot energy in the universe slowly began to cool. At some point, we don't know when, things like quarks, mesons, bosons and other subatomic particles came into existence. Once they cooled a little the collected into atoms.
Think of it this way; on day one after the big bang everything was moving at the speed of light and by definition very hot. But everything was extremely close together which meant heat energy was constant.
When the universe suddenly expanded all this energy had a lot more room to move around and the stuff of the universe started to slow down and therefor cool down. Think of it like boiling water, You take it outside into below zero degree temperatures it will slowly cool down until it goes from its steam point to its solid point.
