007skaty Sort everyday stuff to discover how invisible dark matter holds the universe together.
007skaty These leading dark matter candidates only interact via gravity and the weak nuclear force, explaining how trillions slip by us.
Through which two fundamental forces are Weakly Interacting Massive Particles hypothesized to interact?
Detergent science: The axion dark matter candidate was named after a brand of grocery store laundry detergent.
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?
