modified Newtonian dynamics; MOND
A hypothesis in astrophysics that modifies Newton's laws to explain galaxy rotation curves without dark matter.
Modified Newtonian dynamics is a theory that attempts to explain galaxy rotation curves without assuming dark matter.
Dark matter, the mainstream explanation for galaxy rotation curves, which MOND seeks to replace.
Classical Newtonian mechanics, which MOND modifies at very low accelerations.
Compound of 修正 (modification) + ニュートン (Newton) + 力学 (mechanics). Calque of English 'modified Newtonian dynamics'.
