Dark matter bends to classical gravity, according to a Geneva study

A team from the Department of Theoretical Physics at the University of Geneva has sifted through more than a hundred million galaxies to test a key point of cosmology: does dark matter, five times more abundant than ordinary matter and invisible because it neither emits nor reflects light, follow the same laws of gravity as the rest of the Universe. The verdict is clear. Cosmologists observe that dark matter falls into gravitational wells just like ordinary matter, indicating that it is subject only to gravitation and does not defy classical laws.
