The Origin of Everything.

It all comes down to companionship more commonly known as love. It is this the reason why. Now we in the field of science can continue to talk endlessly around this truth and speak half truths, or, we can speak the truth, the whole truth, and nothing but the truth which is that the purpose of self otherwise known as the meaning of life is love. That's all there really is to it.
~ Wald Wassermann, Physicist
