Dark matter, composed of particles that do not reflect, emit or absorb light, is predicted to make up most of the matter in the universe. Its lack of interactions with light, however, prevents its direct detection using conventional ...
In the first millionths of a second after the Big Bang, the universe was a roiling, trillion-degree plasma of quarks and gluons—elementary particles that briefly glommed together in countless combinations before cooling ...
