Just under 11,000 days ago, a human set foot on the moon. With this new system of energy transmission, humanity is possessed with the ability to see the largest reflection of its collective mind ever. The luminance of our consciousness grows with every change to every page of every site across the Web of humanity. Since we do know that all things in Cosmos are forms of energy, physics seeks a definition of the word which contains, makes, and gives life to everything. Every galaxy, star, planet, ocean, rock, plant, animal, human, and thought is 'energy'.
Energy is indeed an interesting subject to study.
20th Century physics has been constructed based upon theories which have attempted, however perfectly or imperfectly, to describe the fundamental nature of energy. Most physicists have been educated to understand that the definition of energy is 'that which does work'. Since physics is a principal cornerstone of Western thought, any major advancement in understanding 'that which does work' represents an inflection point in the trajectory of human history. Indeed, the electrons making up the images of the letters you are reading at this moment are forms of that. You are that.
