A modified theory of gravity explains the self-interaction of dark matter. — •Albrecht Giese — Taxusweg 15, 22605 Hamburg

New investigations using the James Webb telescope have revealed inconsistencies in the explanations for the formation and distribution of dwarf galaxies in the early stages of the universe.

Current cosmological theory suggests that this can be explained by assuming that dark matter particles self-interact. However, according to our current understanding of gravity, such an interaction is impossible.

We will demonstrate that there is a model of gravity based on a different dependence of gravity on mass. This model not only solves the issue of rotation curves, but also that of the self-interaction of dark matter-related particles.
