A collision of two extraordinarily dense, collapsed stars in the distant universe is providing potential clues to the axion, a dark matter candidate first proposed half a century ago.
Plasma could be wrangled to collide photons and yield matter, according to physicists who ran simulations to explore the practical applications of a world-famous equation.
Scientists from the Telescope Array Collaboration have detected an ultrahigh-energy cosmic ray, a discovery that’s challenging our current understanding of exotic cosmic phenomena and their origins.
Astronomers looking at ancient light seen by the Webb Space Telescope have found three pinpricks that they think could be “dark stars,” theoretical objects powered by dark matter.
