Some possible consequences of Zel’dovich’s cosmological term

Summary

According to Zel’dovich, the energy tensor of the polarized vacuum of quantum field theory implies the existence of a non-zero cosmological A term in i Einstein’s gravitational equation. I investigate the consequences of Zel’dovich’s λ in a spatially flat isotropic universe with the Hubble parameterH proportional tot ⁻¹ (t = the cosmic time); I find:tH > 2/3, -1 <q < 1/2, λt² = constant,Gt = constant, whereq is the deceleration parameter andG the gravitational coupling; another result is a mass creation process throughout the universe at the rate 10⁻⁴⁷gs⁻³ cm⁻³. This approach explains two well-known empirical relations connecting microphysics to cosmology.
