Since the epochal event of the big bang, several physical parameters have been responsible for the evolution of the universe and for keeping it sustainable for various life forms as we know it. In this article we will discuss three such parameters or principles starting with the fundamental or coupling constants. A fundamental constant is an important part of any physical law. Some of the famous fundamental constants of interest to physicists include but are not restricted to the speed of light, the gravitational constant, Planck’s constant, the fine-structure constant, and many more. For more information, look at the table below that gives a non-exhaustive list of fundamental constants.

Another topic of relevance and our second principle in the title is the concept of fine-tuning according to which even a slight deviation between the values of physical observables...
