Query: A New Universal Constant Determining Expansion of the Universe   A new universal constant of expansion has been discovered with amazing
predictive power once its density-time relations have been deciphered. The new
constant is kappa, the product of the gravitational constant, and the average
total mass-energy density of our universe and the square of the cosmic time.
With the ten parameters known, this relation promises to account for the
expansion of our universe from its beginning into the far future. The most
important and most difficult item is cosmic time and its scaling relation with
the densities. The new cosmological theory will be presented in this paper to
show good predictions of the cosmological parameters. The theory will be used
in a second paper to show that acceleration of the expansion rate is not needed
to account globally for the exploding-star supernova Ia radiation that has
traveled such great distances in our expanding universe.
