From Quantum Zeitgeist site: Quantum Models Link Energy, States with New Symmetry by Muhammad Rohail T

Lucas Lamata, for Nanotechnology London, investigates a previously overlooked symmetry present within both the quantum Rabi model and the Dirac equation, potentially offering solutions to fundamental problems in physics. A total symmetry principle is proposed, stating that total energy remains zero, alongside the constraint that positive energy excitations possess corresponding negative energy counterparts. This approach bypasses the need for the Dirac sea concept and may automatically resolve issues surrounding the renormalization of quantum gravity, as well as the existence of dark matter and dark energy, alongside cancelling zero-point energy. This reinterpretation of established models highlights the key role of enforcing symmetry principles in theoretical frameworks...
