The Mystery of the Universe's Missing ‘Normal’ Matter Has Begun to Unravel
“There are the longstanding challenges with pinpointing dark energy and dark matter, two invisible components that together make up more than 95 percent of the cosmos. But there is also the lesser-known problem of missing baryon particles.”
Half the universe’s missing matter has just been finally found
“You have probably heard about the hunt for dark matter, a mysterious substance thought to permeate the universe, the effects of which we can see through its gravitational pull. But our models of the universe also say there should be about twice as much ordinary matter out there, compared with what we have observed so far.”
Astronomers Found Two Massive Galaxies Amid an Ocean of Dark Matter
“The discovery provides new details on the role that dark matter played in assembling large structures in the universe. Astronomers say the amount of dark matter that “clumped” in one area in order to create galaxies this large would have been quite rare.”
