MORE PHYSICS BEHIND THE CHANGE: Relating Radius with Period

The information presented below were all obtained from various internet sources (all of which are listed below) and this post is a compilation and a summary, in simple words for ease of understanding of the readers, of the whole process taken into consideration for the research.) Nothing has been directly pasted from a single source. 
Specific to this post, its just an interpretation of the former post using physics and algebra to prove the theory right.
We can show more clearly how a change in the radius of the earth would effect the period (the length of the day) :

Therefore, we can see that, a lower R(new) value will give us a lower T(new value) and vice versa. This explains how, due to the reduced radius of the earth, the length of the day, that is, the Period of the earth was also reduced.
