Signs of Disturbance in Nearby Dwarf Galaxies indicate an Alternative Gavity Theory

The dwarf galaxy NGC1427A flies through the Fornax galaxy cluster and undergoes disturbances which would not be possible if this galaxy were surrounded by a heavy and extended dark matter halo, as required by standard cosmology.

According to the standard model of cosmology, the vast majority of galaxies are surrounded by a halo of dark matter particles. This halo is invisible, but its mass exerts a strong gravitational pull on galaxies in the vicinity. A new study challenges this view of the Universe. The results suggest that the dwarf galaxies of Earth’s second closest galaxy cluster — known as the Fornax Cluster — are free of such dark matter halos.

Dwarf galaxies are small, faint galaxies that can usually be found in galaxy clusters or near larger galaxies...
