Do the Fundamental Constants Vary in the Course of the Cosmological Evolution?
A. Ivanchik, E. Rodriguez, P. Petitjean +1
We estimate the cosmological variation of the proton-to-electron mass ratio μ=m_p/m_e by measuring the wavelengths of molecular hydrogen transitions in the early universe. The anal…
