Oldest radio-wave explosion ever found could be used to weigh the universe, astronomers say (www.livescience.com)

Astronomers have discovered the most ancient "heartbeat" radio signal, and they want to use it to find the missing half of the universe's matter.

The mysterious signal โ€” a fast radio burst called FRB 20220610A โ€” was found 8 billion years into the universe's past, its light rhythmically pulsing from the heart of three merging galaxies.

As the fast radio burst (FRB) is 1.5 times more ancient and distant than the previous record holder, its light could be used to find an approximate weight to the universe โ€” and perhaps to figure out where half of its matter went, astronomers say. The researchers published their findings Oct. 19 in the journal Nature.
