Description
Milgromian dynamics (or Modified Newtonian Dynamics, MOND) is a major alternative to particle dark matter proposed in 1983 by Mordehai Milgrom. MOND modifies the non-relativistic laws of gravity and/or inertia at low accelerations, below a characteristic acceleration scale a0. In this proposed contribution, I will showcase the content of the first "MOND white paper", which results from the collaboration of more than 60 researchers across the globe working on different aspects of MOND. The MOND white paper covers fundamental theories, numerical simulations, and observational tests across all astronomical scales, from the Solar System to Cosmology. In particular, I will focus on the successful a-priori predictions that MOND made on galaxy scales, as well as the long-standing problems it faces in galaxy clusters. I will also mention recent relativistic extensions of MOND that allow reproducing the cosmic microwave background, the linear matter power spectrum, and the observed behavior of gravitational waves.
