Astronomers have found a way to observe the missing matter (missing baryons) in our universe which connects galaxies, Newsweek reported. This could help researchers to understand the time during the Big Bang (beginning of the universe). For so many years, scientists have been searching a clue on this missing matter which is holding our universe.
Scientists believe that about 70 percet of our universe is made up of a mysterious energy (Dark Energy) which is responsible for its expansion. The objects like planets, stars, and galaxies —which can be seen — are made of the normal matter, and the remaining, which is hidden, is made up of the dark matter.
Research on the missing matter
The teams of researchers are working to figure out the nature of the dark matter and dark energy, while other teams of researchers are trying to solve the mystery of ordinary matter (protons, neutrons, electrons), according to Futurism. Scientists are one their way to solving the mystery behind the missing matter. This also takes into account our own galaxy, the Milky Way.
The two teams of researchers claimed to solve the mystery behind the missing matter. One study was conducted at the Institute of Space Astrophysics (ISA) in Orsay, France, and the other was at the University Of Edinburgh, UK.
The missing baryon problem
The researchers looked into the 3-D map designed by the Sloan Digital Sky Survey and predicted that the galaxies are connected with baryons.
After that, they used the map produced by Planck satellite in 2015, which shows the cosmic microwave background (CMB), an electromagnetic radiation left over from an early stage of the universe. These radiations pass through a hot gas, so some of them scatter, leaving behind a trace of the gas. In this way, the researchers can see strands of matter that could not observe normally.
The researchers from both teams claimed that missing baryons are present in the universe in the form of hot filaments of gases that connect galaxies. They also found that the matter was denser as compared to average. IAS's team studied 260,000 pairs of galaxies, and Edinburg team examined more than a million of pairs.
Hideki Tanimura, a researcher at ISA, revealed in his paper that the matter was 3 times denser, but on the other hand, Anna de Graaff of the University of Edinburgh said it was six times denser, Newsweek reported. It was concluded that the gas that connects galaxies was dense enough to make filaments.
