Galaxies and clusters of galaxies would form in the Universe, but they would be much darker, since only very large bodies with a mass of several solar masses would become stars, in which thermonuclear reactions of helium combustion would begin. Moreover, the lifetime of these stars would be extremely short – several million years. The universe would quickly become completely dark.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
