On Star Formation in the Early Universe and Its Implications

A new cosmological model, which argues that Gravity is not fundamental but has originated and evolved over time, also attempts to explain dark matter, arguing that it's shaped by stars and galaxies that could not evolve due to their initial low gravity. In this work, we analyze which types of stars, depending on their mass, could have reached states of main-sequence equilibrium and stability under the early Universe conditions and which could not have done it it according to this model. Based on the results obtained, we study the possibility about failed stars could explain the degree of dark matter present in the Universe. We also analyze whether the new model can coherently explain the high luminosity observed in many early galaxies, as well as their degree of metallicity. We also ask whether large early supermassive black holes are consistent with this model.
