Abstract

We show that within the cosmology associated with conformal gravity the age of the universe is given as 1/H₀, to thus overcome the current cosmological age crisis. We show that while the parameter Ω_mat = ρ_mat / ρ_C takes on all values between zero and infinity in conformal gravity, nonetheless it is of order one (but not identically equal to one) for half a Hubble time to thus naturally explain its current closeness to one without fine tuning. We show that the cosmological constant is naturally of order the energy density ρ_mat of ordinary matter again without fine tuning. We compare and contrast conformal cosmology with that of the standard Friedmann cosmology.
