EROS (Experiments for Relativistic Astrophysics)

EROS (Experiments for Relativistic Astrophysics) is a scientific project designed to study phenomena in the universe that are governed by Einstein’s theory of relativity. It primarily focuses on detecting and analyzing cosmic events such as gravitational lensing—where massive objects like stars or black holes bend light—and dark matter. By observing how light from distant stars and galaxies is affected by gravity, EROS helps scientists better understand the distribution of mass in the universe, including dark matter, and tests fundamental physics related to gravity and the structure of the cosmos.
