For more than a decade the astrophysical community has been gathering observational evidence that seem to contradict the concept of dark matter in favor of new theories of gravity. In this article we summarize the most important ones, from to 2016 to present.

As we have explained in former articles, dark matter was inferred as an additional gravitational source that could explain the flattened rotation curves of spiral galaxies; spiral galaxies were found to rotate at a nearly constant rate, independently of its radius. From Newton’s law and the distribution of visible matter, one would expect the rotational velocity of stars and gas inside a galaxy to decrease with distance, but in the 70’s astronomers found this flattened anomaly, and dark matter was born.

Nevertheless, many teams have found astronomical evidence pointing towards modified gravity models instead. For instance, in 2016, a significant...
