A new cosmological model is proposed that does not require dark energy, yet presents characteristics and trends that are almost comparable to those of the standard model. It differs from the standard model by an "extra path factor" that comes from a central hypothesis and results in an additional distance due to the gravitational radius. This additional distance causes the matter density parameter to rise from 0.5 to 1 from the big bang to the present, which gives rise to a non-zero pressure that drives the present acceleration phase of the universe's expansion. Remarkably, the halving of the density during nucleosynthesis solves the primordial lithium problem, although it introduces a deuterium problem. Finally, the resulting model solves the Hubble tension and the S8 tension, and satisfies all the constraints derived from the most recent accurate measurements of the baryon acoustic oscillation and the angular power spectrum of the cosmic microwave background, despite having one less parameter due to the absence of dark energy. The same hypothesis explains the rotating motion of galaxies on a small scale and produces consequences that are comparable to those of the modified Newtonian dynamics (MOND) theory.However, although the proposed model respects the same principles and physics as the standard model, it needs to be reinterpreted within the framework of the more original space of light to appreciate the naturalness of the hypothesis and its profound implications.
