⚠️ Disputed: the sources disagree.
What was discovered
Milgrom proposed modifying Newton's laws at extremely low accelerations, typical of galactic outskirts, to explain flat galaxy rotation curves without invoking invisible dark matter.
MOND explains individual galaxy rotation curves well, but struggles with other observations, such as the acoustic peaks of the cosmic microwave background, so it has not displaced the dark-matter model.
What it led to
- The dark-matter-versus-modified-gravity scientific debate
- Derived relativistic theories (TeVeS and others)
