Astronomers claim that galaxies are 98%dark matter. Maybe they are wrong

As early as 2016, researchers claimed to have discovered a galaxy almost entirely composed of dark matter and almost no stars. Since the 1980s, researchers have been debating whether these large, dim objects have low mass, such as dwarf galaxies smeared in wide space, or are more like heavy, faint-looking galaxies in the Milky Way, for two reasons :Because they have almost no stars, and because a large part of their mass is dark matter found in the periphery of the Milky Way, the so-called dark matter halo does not emit light.
