The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions ...

The universe's matter-antimatter asymmetry, where matter significantly outweighs antimatter despite their theoretically equal creation at the Big Bang, remains a major unsolved problem in physics.

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

In 1933, astronomer Fritz Zwicky noticed something strange: The universe seemed to have ‘missing mass.’ Something had to account for the space in between cosmic bodies and the gravitational forces ...
