The Theoretical Value of the Cosmological Constant

Authors: Ru-Jiao Zhang

This paper presents a derivation of the theoretical value of the cosmological constant. The approach was based on Einstein’s gravitational field equations, Hubble’s law, and Friedmann-Robertson-Walker model of the universe. The theoretical value of the cosmological constant Λ was found to be: Λ=(2Ho^2)/3 , here Ho is the Hubble constant. The theoretical value is very close to the observational value. Open space (k=-1) and closed space (k=+1) most likely coexist in our universe. The study implies that the expansion of the universe is an inherent property of vacuum space, not by dark matter and dark energy.
