Abstract
The vacuum electromagnetic field has been a mystery ever since Hedrik Casimir [1] proposed in 1948 that it actually existed and could be measured. Many subsequent experiments [2] have confirmed that its vast field strength (over a terawatt/cm2) is real and matches quantum predictions. Radiation pressures as high as 18 psi have been measured from the reflected vacuum light between plates of 10 nanometer separation. All of this creates a mystery. The electromagnetic field strength is more than a terawatt/cm2 everywhere in the universe and yet nothing is melted, ionized or burned up by the field. This paper extracts new insight from Einstein’s famous 1917 paper, credited with the discovery of stimulated emission and still believed today. The result is a practical explanation of the vacuum field and its observed properties.
Highlights
The vacuum field was first suggested when the quantum mechanical solution for a harmonic oscillator predicted a lowest possible energy of 1/2hν rather than the expected zero
We find two clues from Einstein’s 1917 paper on stimulated emission, which suggest a new model for the physical vacuum field
We suggest that this relationship between spontaneous emission and the vacuum field is an important physical linkage
Summary
The vacuum field was first suggested when the quantum mechanical solution for a harmonic oscillator predicted a lowest possible energy of 1/2hν rather than the expected zero. At first no one ascribed much reality to it, but it has become the subject of much research and theoretical modeling since Hedrik Casimir opened the door in 1948 [1] He assumed the zero-point vibration energy (hν/2) of a quantum oscillator for each E & M mode frequency ν, and he computed how much pressure the vacuum field would push on two parallel plates a distance d apart. Still the mystery has remained about photonic fields that demonstrate terawatt/cm power in their ability to push and pull plates and bend electronic orbitals. We find two clues from Einstein’s 1917 paper on stimulated emission, which suggest a new model for the physical vacuum field
