The missing links between galaxies have finally been found. This is the first detection of the roughly half of the normal matter in our universe protons, neutrons and electrons unaccounted for by previous observations of stars, galaxies and other bright objects in space.
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.
Two separate teams found the missing matter made of particles called baryons rather than dark matter linking galaxies together through filaments of hot, diffuse gas.
The missing baryon problem is solved, says Hideki Tanimura at the Institute of Space Astrophysics in Orsay, France, leader of one of the groups. The other team was led by Anna de Graaff at the University of Edinburgh, UK.

Baryons aren't named after Obama, but Trump is petty and stupid...
Baryons and wayward suns,
There be peace when you are done...

There's still a dark matter and dark energy question, they have just tidied up a gap in the observation of normal matter.

(813 posts)and had to go look it up: "Or All the Seas with Oysters" by Avram Davidson which won the Hugo Award for Best Science Fiction Short Story all the way back in 1958. (I must have read it in a collection.)
Anyway, it posits a life form whose three morphological forms are safety pin, wire clothes hanger, and bicycle. And they are very dangerous...

Now is the perfect time to launch my dark matter-based cryptocurrency!
