Much of the universe's regular "baryonic" matter is spread through intergalactic space and in diffuse halos around galaxies, researchers proposed after studying the behavior of fast radio bursts emitted from deep space.

Bright flashes of enigmatic radio waves have helped illuminate some of the missing matter in the universe, astronomers say in a new study.

The mechanism used to detect and measure the missing ordinary matter involved phenomena called fast radio bursts, or FRBs - powerful pulses of radio waves emanating from faraway p
