Dark Energy's Role in General Relativity

The name dark energy was given to the energy responsible for accelerating the contents of the universe “outward”. This energy is being called “dark” until a theory could be found to account for it. The field of physics has been built on the scientific method fostering well-established theories that build on one another. However, so far, no derivations stemming from our current mathematics, expressing our most validated theories, has been able to reveal the nature of “dark” energy. It may be time to consider... What if it is impossible to derive the nature of dark energy using the mathematics expressing our current theories? What if a new model of the universe is required; a more basic model to which math is applied? A model that starts with only one ingredient and its associated energy as the only way to reveal the nature of dark energy? Such a basic elementary model would have to be derived independently from our current complex theories and yet be able to derive our current theories. The new model could then define dark energy and reveal the role dark energy plays in gravity, general relativity, and much more.
