2) There are so-called complementary variables. The most known pair is momentum and position. These are connected via an Uncertainty Principle (e.g. Heisenberg Uncertainty)

Energy is also in such a conjugate variable pair together with duration (i.e. the product of how exactly you can measure the energy of a system and how exactly you can measure the moment in time of that energy state is uncertain to below a certain value). So this could point to energy being a symmetry breaking together with time (which makes sorta sense because without a measure of time the idea of energy makes no sense and vice versa.)

does this mean you can create energy by causing a gravitational phenomena in a system? how would such an event likely to occur in reality? what does the concept of energy entail in such a scenario
i don't know anything about symmetry, or symmetry breaking, theory wise as it pertains to physical laws (any links or explanations would be appreciated) obviously, the universe is not typically symmetrical, to conceive of nothingness forming a dichotomy of thermodynamic energy and vectorial energy(is gravitational, 'negative' energy vectorial or am i way off? I don't really know how to picture such a concept), where the word energy changes its meaning is interesting to me. it sort of makes sense in that gravitational displacement causes kinetic and thus thermodynamic displacement, the idea that these two cancel each other out/are linked in a foreign abstract energy balancing act seems to make sense intuitively, but is it more wanting to follow pre 'existing' theory of an equilibirum when in reality we can never know if one exists, and may just be going off existing held theories or a pine that an equilibrium is enforced by nature, because to reject such a notion would lead to a realm of chaos that we cannot explain? what would a thought experimental type scientific rejection of equilibrium of energy lead the map of the cosmos, and potential theories of energy/matter to look like?
Is there any observable data contrasting the heat map of the universe, of gravitational phenomenon?
