The radio signals of mysterious deep space revealed the location of the “missing matter of the universe” of the universe “of the universe”
About half of the whole regular question in the universe has not been taken into account – so far.
In a new study, researchers say that using short extragalactic flashes called fast radio (FRBS), they have taken into account all the baryonic material – the “normal” matter which constitutes stars, planets and other objects which interact with light – which we expect to find in the universe. A large part of the “missing” matter spreads through space between the galaxies, according to the study, which was published on June 16 in the journal Natural astronomy.
Baronic material, which is made up of particles like protons and neutronsrepresents only 5% of the universe. Another 27% is invisible dark matterAnd the rest is a mysterious black energy which leads to the accelerated expansion of the universe. But scientists could only observe half of the Baryonic matter that has been produced for being produced during the Big Bang.
To take into account the remaining question, the researchers turned around 69 FRB to light up the intergalactic space which is between gusts and the earth. Nobody knows what causes FRB, but most powerful and long -lived radio flashes come from outside the Milky Way.
“The FRB shine through the fog of the intergalactic environment, and by measuring precisely how light slows down, we can weigh this fog, even when it is too weak to see”, co-author of the study Liam ConnorAn astronomer at Harvard University, said in a statement.

Using this technique, Connor and his colleagues have found that around 76% of regular material in the universe is in the intergalactic environment, the hot gas which fills the space between galaxies. About 15% can be Found in the halos of galaxies – Hot and spherical regions on the edges of galaxies. The remaining baronic question constitutes the stars, the planets and the cold gases inside the galaxies themselves, proposed the team.
“It is as if we see the shadow of all the bars, with frbs as a backlight”, co-author of the study Vikram delightedsaid a Caltech astronomer in the press release. “If you see a person in front of you, you can know a lot about them. But if you just see their shadow, you always know that they are there and almost their size.”
The results explain observation of all the baronic materials of the universe for the first time, by preventing not only if this affair exists but also where it is concentrated in the universe.
“I would say that the problem of missing bars is essentially resolved,” Nicolás TejosAn astronomer from the Pontifical Catholic University of Valparaíso who was not involved in the study, said Science review. “Thanks to Frbs, we were now able to close this Baryon budget.”
In future studies, the team hopes to take advantage of the Synoptic Array 2000 deep, a proposed network of 2,000 radiotelelescopes which will scan the whole sky over five years, to locate up to 10,000 new FRB per year and investigate the baryonic question of the universe with even more details.
