The Cosmological Constant (Lambda) is not Really Constant but the Function on a Gravitational Radius

A general line element and a general metric tensor are defined. The related Einstein's field equations of a gravitational potential field in a vacuum, including parameter lambda, have been derived as a function of two parameters alpha and alpha prime. These parameters are functions on the energy state in each space-time point. The parameters alpha and alpha prime are identified in a gravitational field by the solution of the Einstein's field equations. Parallel with this, we find out that the so-called cosmological constant, lambda, is not really constant, but a function on gravitational radius, lambda = f(r). This discovery is very important, among the others, for cosmology. One of the consequences is the new form of the acceleration equation of the universe motion that can be attractive (negative) or repulsive (positive). According to the observations, the repulsive acceleration gives rise to accelerating expansion of the universe at the present time.
