How does the mass of a hypothesized axion particle compare to that of an electron?
Which household product brand inspired the name of the hypothetical dark matter particle called the axion?
A device used to discover, measure, or identify the presence of something. In late 2009, scientists built a dark matter detector deep inside South Dakota's abandoned Homestake gold mine.
What astronomical acronym was used to describe normal, non-shining dark matter candidates like black holes and dead stars?
Why can't cold cosmic dust and gas clouds explain the universe's missing dark matter?
