The measured energy density of the vacuum has a disturbing discrepance with the one theorized by imposig Poincare invariance in QFT, usually referred to as the "vacuum catastrophe".
On the other hand the Heisenberg indeterminacy principle leads to a nonzero vacuum expectation value for the Hamiltonian of the quantum fields values. This seems independent of perturbative or non-perturbative treatments unless the HUP is considered itself a mathematical artifact.
What would be the arguments countering the above apparent obstructions to Lorentz invariance of the QED vacuum?
