Astrophysicists make observations consistent with predictions of an alternative theory of gravity

In the Hyades star cluster (top), the number of (black) stars in the front tidal tail is significantly larger than those in the back. In the computer simulation with MOND (below), a similar picture emerges. Credit: University of Bonn An international team of astrophysicists has made a puzzling discovery while analyzing certain star clusters. The …

Dwarf Galaxy NGC1427A

New discovery points to an alternative theory of gravity

The dwarf galaxy NGC1427A passes through the galaxy cluster Fornax and experiences disturbances that would not be possible if this galaxy were surrounded by a heavy and extensive dark matter halo, as required by standard cosmology. Credit: ESO Perturbations in dwarf galaxies in one of the galaxy clusters closest to Earth point to a different …
