The Elementary Oscillation of Dark Energy

An equivalence principle is elaborated and founded. With it a third development of H.-O. Carmesins theory of quantum gravity is presented. The theory combines quantum physics with general relativity and is based on three numerical inputs only: the constants G, c and h. In particular the zero - point oscillations of the gravitational field are elaborated. Its energy is in accurate accordance with the observed dark energy, whereby the difference is 0.073 % only. We interpret this as a strong evidence for the thesis that these elementary oscillations present the dark energy. These elementary oscillations emerge at various wavelengths. The resulting polychromatic vacuum explains the difference of the measured Hubble constants with an accuracy of 1 %.
