Assuming that the universe is homogenous and isotropic and applying Gauss' flux theorem for gravity, it follows that the gravitational field of the visible universe can be calculated as if the entire mass of the visible universe is located in one point. Taking into account that the mass of the visible universe is M=2x10^{53} kg, it appears that the entire visible universe is inside a {\it photon sphere} of radius R_{ps} = 14.3 Gpc. The current model for the visible universe must be corrected to account for the fact that measured horizon distance of 14.0 \pm 0.2 Gpc is not a straight line. Rather it is an arc of a circle with that length, because all photons are inside the photon sphere. Our model interprets the visible universe as a surface of a sphere (or an inside of a sphere shell) with radius 4.46 \pm 0.06 Gpc and an event horizon, located on that sphere (shell), with size of 14.0 \pm 0.2 Gpc. The model predicts CMB redshift and time dilatation of Type Ia supernovae by gravitation. It explains, without inflation theory, the isotropy and uniformity of the CMB. It predicts the correct value for the Hubble constant H_0 = 67.26 \pm 0.90 km/s/Mpc, the cosmic expansion rate H(z) in agreement with observations, and the speed of the event horizon. Through relativistic energy correction, our model also provides an explanation for critical density without use of dark matter. It explains that Type Ia supernovae redshifts are not related to the accelerated expansion of the universe and dark energy. It explains the reason for the established discrepancy between the non-covariant version of the holographic principle and the calculated dimensionless entropy (S/k) for the visible universe, which exceeds the entropy of a black hole. The model is in agreement with the distribution of radio sources in space, Type Ia data, and data from the HUDF optical and near-infrared survey.
