The Universe’s Missing Matter. Found!

In the 1960s, astronomers began to notice that the Universe appeared to be missing some mass. Between ongoing observations of the cosmos and the the Theory of General Relativity, they determined that a great deal of the mass in the Universe had to be invisible. But even after the inclusion of this “dark matter”, astronomers could still only account for about two-thirds of all the visible (aka. baryonic) matter.

This gave rise to what astrophysicists dubbed the “missing baryon problem”. But at long last, scientists have found what may very well be the last missing normal matter in the Universe. According to a recent study by a team of international scientists, this missing matter consists of filaments of highly-ionized oxygen gas that lies in the space between galaxies.

The study, titled “Observations of the missing baryons in the warm–hot intergalactic medium“, recently appeared in the scientific journal Nature. The study was led by Fabrizio Nicastro, a researcher from the Istituto Nazionale di Astrofisica (INAF) in Rome, and included members from the SRON Netherlands Institute for Space Research, the Harvard–Smithsonian Center for Astrophysics (CfA), the Instituto de Astronomia Universidad Nacional Autonoma de Mexico, the Instituto Nacional de Astrofísica, Óptica y Electrónica, the Instituto de Astrofísica de La Plata (IALP-UNLP) and multiple universities.

Title is misleading. These particles eluded scientists' observation, but they were always there....:D

They never confirm these things, it's always may or a possibility..... would love it when the experts confirm beyond all reasonable doubt!
Almost impossible to do. But every experiment that doesn't disprove a theory helps to increase the certainty that it is correct.
