It is my understanding that the ground state of the vacuum refers to 'quantum mechanical harmonic oscillators'. Can that be interpreted as the lowest absolute vacuum vibration energy of a gigantic magnitude?
Is the zero-point energy the vacuum ambient average energy above the vacuum ground state?
The vacuum energy is generally believed to be tiny but some physicists disagree. Can I interpret the vacuum energy as an energy difference between zero-point energy and the actual energy above the ground state energy?
It is my understanding that the above ground state energies are the vacuum fluctuations described as spontaneous emission and absorption of electromagnetic waves and particle pairs. Are energies between elevated vacuum states and vacuum ground state included?
