This result therefore undermines alternative approaches, including
modified Newtonian dynamics (MOND), a theory of gravity that does without dark matter by suggesting gravity works slightly differently than in Einstein's framework, the team says.
According to the theory called MOND (
MOdified Newtonian Dynamics), the attraction between two masses obeys Newton's laws only up to a certain point.
Either, the galaxies contain large quantities of unseen matter called "dark matter," or Newton's laws need to be modified for extremely small accelerations according to a
Modified Newtonian Dynamics (MOND) proposed by Israeli physicist Mordechai Milgrom (MILGROM 1983).
His
Modified Newtonian Dynamics (MOND) is an empirical correction of Newton's laws of gravity and inertia, proposed as an alternative to dark matter.
Yet predictions made using the alternative hypothesis
Modified Newtonian Dynamics (MOND) succeeded in anticipating the observations.
In an alternative theory, called
modified Newtonian dynamics, or MOND, forces such as gravity would produce small accelerations in addition to that which standard Newtonian physics predicts.
Alternative theories include
Modified Newtonian Dynamics, or MOND.
This value of acceleration is also the "critical acceleration" of
modified Newtonian dynamics MOND,
That's the case in this issue, where you'll find (beginning on page 30) an article about
Modified Newtonian Dynamics. The brainchild of astronomer Mordehai Milgrom, MOND posits that when gravity gets really weak--as it does in the outskirts of galaxies--it no longer follows Isaac Newton's inverse-square law.
One of these is
Modified Newtonian Dynamics (MOND), which was hypothesized in 1983 by Moti Milgrom a physicist at the Weizmann Institute of Science in Rehovot, Israel.
