This is an attempt to recognize a base physical property of the universe itself that also describes why it must exist according to this property. This approach is very counterintuitive, but should not be misinterpreted as ontological or metaphysical. Intuition is a human notion based on everyday human experiences... the existence of the universe in it's entirety is not an everyday human experience and, thus, should not be limited by those notions. This is an analysis of a physical observation of the universe itself: First, think about the concept of 'nothing' or 'zero'. These are simply just that, concepts, used to help illustrate a human-made string of reasoning. But these concepts are not, themselves, physical properties of the universe. When we hold an apple in our hand we can say we have an apple, but when we take it away we cannot say we are holding 'no apple' anymore than we can say we are holding 'no egg', or 'no rock', or 'no anything' for that matter. It's just a man-made concept to help illustrate that line of thinking. In actuality, there is no such thing as 'nothing', and that is a physical property of the universe itself. Even in 'empty' space there are a slew of virtual particles bubbling about as well as various forces interacting with each other. Since matter and energy are never created nor destroyed (simply altered), and the universe is made of matter and energy... it can be assumed that the universe would never stop existing by it's very own physical properties. It can also be conjectured from this line of logic that since 'nothing' is not a physical property of the universe itself, it exists as a result of some base rule set, and was not required to have been created from 'nothing'.
