    Dark does not mean "unfound". In this context, it means that it doesn't emit a detectable amount of electromagnetic radiation. And yes, the majority of the energy density of the universe is "dark" in the mainstream model. It is certainly plausible that a modified theory of gravity could explain the apparent dark energy, eliminating the largest dark component, but no model has yet distinguished itself.
