I found these article comments very interesting:

The theory that energy comprises the entire universe is old as the hills. The ancient Chinese art of Qigong is based on the same idea that Qi is the true nature of everything and everyone. It applies the principles of energy awareness to personal development and healing, but it is important to recognize that everything is energy on the macro scale. I am currently studying the ways of understanding how the macro and micro scales are connected. Would love to discuss your theory.

I’ve always assumed this was the case…

From my point of view, every “thing” in the current universe, including spacetime, owes its origins to the Big Bang, when there was ONLY energy and nothing else, not even space or time. The Big Bang was simply a phase change (like water to ice) as kinetic energy began to subside through its own unimaginably concentrated interaction, finally yielding the first primordial “crystals” or “things,” which, for the moment, we can call strings. Of course, the new, first presence of these “things” demanded differentiation; in other words, you can’t have a “thing,” such as a string, without being able to distinguish it materially from others, thereby yielding SPACE, in which “things” can be distinguished. These “things” interact through cause and effect, necessitating TIME.

So, the phase change from pure energy to “things” yielded SPACETIME.

Since every “thing” demanded its own immediately surrounding domain of SPACETIME, space underwent inflationary expansion and commensurate reduction in kinetic energy, i.e., cooling, yielding exponentially more phase changes, i.e., “things.” (Think of this as an “unfolding” of spacetime around each emerging “material” constituent, albeit at the Plank scale.)  This crystallization of pure energy into things and spacetime is what we call The Big Bang. This rapid sequence of phase changes in the ever expanding and continuously cooling domain of spacetime yielded other successive things, including quarks, protons, electrons, and so forth, right up the chain of subatomic, atomic, elemental, and ultimately chemical and biological formation.

This process continues today and is characterized by the bubbling in and out of existence of so-called virtual particles, each of which unfolds its own highly localized domain of spacetime. This ongoing, ever-present, vast, and constant unfolding of spacetime at the Planck scale throughout the universe is what we call Dark Energy, expanding spacetime at exponentially greater speed as virtual particles boil in and out of existence. Some of the fundamental constituents of this process have mass-like properties, yielding Dark Matter.

With that, I’ll leave the mathematics as an exercise for the reader. :-)
