I Dark Matter , Dark energy and the Dirac equation

[GaloisGroup]

TL;DR Summary

Does the exponential addition of added energy at universal scales violate conservation?

The Dirac equation suggest that vacuum space is really quite busy with virtual particles popping in then annihilating each other. Even “empty space” contains energy. I am having difficulty with what some folks in the physics community are saying about the universe not being a closed system at scale. Dark energy is causing the creation of more space and hence it seems there is a massive energy imbalance somewhere or, what’s more likely and is obvious; we know nothing about “dark energy” and folks are hand waving. Sorry if this question has already been addressed.

Can you cite a scholarly reference that motivates and supports these statements?

Virtual particles, by definition, are not real particles. They are only an aid to calculation.

Dark energy does not cause expansion. It causes acceleration of the expansion. But a universe void of dark energy could still expand. Energy is not conserved globally in an expanding universe, whether it has dark energy or not.
