Testing cosmological variations of fundamental physical constants by analysis of quasar spectra
D. A. Varshalovich, A. Y. Potekhin, A. V. Ivanchik +2
Contemporary multidimensional cosmological theories predict different variations of fundamental physical constants in course of the cosmological evolution. On the basis of the QSO…
