A proton’s mass is just under 1 GeV/c², and most WIMP searches have focused on the mass range between 10 and 1,000 GeV/c². (Particle physicists find it convenient to measure masses in units of ...

Scientists believe dark matter must exist to account for astronomical observations that suggest an unidentified source of mass in the cosmos. Dark matter has evaded a wide variety of detection ...

For ordinary matter, momentum is given by the formula P = mv, where P is momentum, m is mass, and v is velocity. Even tiny amounts of matter can have vast amounts of momentum if the matter is ...
