Modified Gravity & Current Observational Constraints: Foundations

Modified-gravity theories ask whether some phenomena attributed to dark matter could instead reflect departures from standard Newtonian or relativistic gravity. Comparing dark-matter and modified-gravity predictions tests foundational gravity physics and forces models to explain multiple independent observations simultaneously.

A modified law changes the relationship between baryonic mass and gravitational acceleration, potentially reducing the amount of unseen matter required in galaxies.
