# Modified Newtonian Dynamics, an Introductory Review

@article{Scarpa2006ModifiedND, title={Modified Newtonian Dynamics, an Introductory Review}, author={Riccardo Scarpa}, journal={arXiv: Astrophysics}, year={2006}, volume={822}, pages={253-265} }

By the time, in 1937, the Swiss astronomer Zwicky measured the velocity dispersion of the Coma cluster of galaxies, astronomers somehow got acquainted with the idea that the universe is filled by some kind of dark matter. After almost a century of investigations, we have learned two things about dark matter, (i) it has to be non‐baryonic — that is, made of something new that interact with normal matter only by gravitation— and, (ii) that its effects are observed in stellar systems when and only…

Modified Newtonian Dynamics (MOND): Observational Phenomenology and Relativistic Extensions

- PhysicsLiving reviews in relativity
- 2012

It is shown that many of these puzzling observations are predicted by one single relation — Milgrom’s law — involving an acceleration constant a0 on the order of the square-root of the cosmological constant in natural units.

Modified Newtonian Dynamics and Dark Matter from a Generalized Gravitational Theory

- Physics
- 2011

Vast amounts of data clearly demonstrate discrepancies between the observed dynamics, in large astronomical systems, and the predicted dynamics by Newtonian gravity and general relativity. The…

A large-scale heuristic modification of Newtonian gravity as an alternative approach to dark energy and dark matter

The peculiarities of the inverse square law of Newtonian gravity in standard big bang cosmology are discussed. It is shown that the incorporation of an additive term to Newtonian gravitation, as the…

Scale invariance at low accelerations (aka MOND) and the dynamical anomalies in the Universe

- Physics
- 2016

Galactic systems, and the Universe at large, exhibit large dynamical anomalies: The observed matter in them falls very short of providing enough gravity to account for their dynamics. The mainstream…

The two body problem in the presence of dark energy and modified gravity: application to the Local Group

- PhysicsJournal of Cosmology and Astroparticle Physics

We explore mass estimation of the Local Group via the use of the simple, dynamical `timing argument' in the context of a variety of theories of dark energy and modified gravity: a cosmological…

Galaxies as simple dynamical systems: observational data disfavor dark matter and stochastic star formation

- Physics
- 2014

According to modern theory, galactic evolution is driven by the dynamics of dark matter and stochastic star formation, but galaxies are observed to be simple systems. The existence of dark matter…

MOND laws of galactic dynamics

- Physics
- 2014

MOND predicts a number of laws that galactic systems should obey irrespective of their complicated, haphazard, and mostly unknowable histories -- as Kepler's laws are obeyed by planetary systems. The…

Searching for MOND in scalar–tensor theories of gravity

In this paper, I study spherically symmetric solutions in a simple class of geometric sigma models of the Universe. This class of models is a subclass of the wider class of scalar–tensor theories of…

Alternatives to dark matter: Modified gravity as an alternative to dark matter

- Physics

The premier alternative to the dark matter paradigm is modified gravity. Following an introduction to the relevant phenomenology of galaxies, I review the MOND paradigm, an effective summary of the…

K-MOND (with "Dark Matter" as a distinction between Inertial and Gravitational Mass)

- Physics

In this work we definitely prove a possibility that Milgrom's modified Newtonian dynamics, MOND, can be consistently interpreted as a theory with the modified kinetic terms of the usual Newtonain…
