An immaterial domain wouldn't be natural (or united with the material domain in a common uni-verse), so it wouldn't be a scientific subject matter. Time in the natural sense is part of spacetime, which is material, and that supposedly originated with the Big Bang 13.8 billion years ago. You seem to be talking about time, space, and energy in abstract, mathematical or logical senses, which is to say you're dealing with metaphysics, not so much with science. The scientific and metaphysical questions about the origin of the universe are likely quite different. Scientific methods can go only so far since they're tied to observation.
