Essential Physics.

The observable universe is incredibly vast, containing billions of galaxies each with billions, trillions, gazillions of stars and planets while also containing objects and events in the universe that release incredible amounts of energy, such as supernovae or active galactic nuclei, which can release more energy in a few seconds than our sun will release in its entire lifetime, and yet the total energy of the whole universe adds up to zero. Wait. What?! No worries. It's not that complicated as some make it sound. The total energy of the universe is not zero; it is Self. It is just that it is not good to be by Oneself which is why Self is Diverse in Life.
