Scientists Develop a New Method to Detect 'Normal Matter' Lost in the Universe

A scientist and his team from the University of Sydney have developed a new method that can be used to detect missing baryonic matter, which is in our models of the universe, but we could not detect by measuring its presence.
According to the models of the universe we have developed so far, about 95 percent of the universe consists of dark matter and dark energy. Dark matter and dark energy are still largely mysterious as you know.
The remaining 5 percent of the universe is made up of baryonic matter, which we can call 'normal matter', which is the source of everything else. Despite this 5 percent rate that emerged after the measurements carried out in the 90s, another unknown at this point emerges. Because scientists were able to detect only half of the baryonic matter, which they found to make up 5 percent of the universe. In other words, even baryonic matter, which is a substance we can actually describe, we are only aware of half of it yet.
Many scientists are working on this matter, which is in the 5 percent of our universe, but half of which we have not yet detected, using different methods, and various methods are trying to measure this substance.
Yuanming Wang, who is a PhD in physics at the University of Sydney, is one of the scientists who studies to measure baryonic matter and has developed an important method at this point.
Wang, who conducted the research with many scientists who conducted research on this subject, thinks that the undetectable baryonic matter is mostly located in the form of cold gas clouds between galaxies.
These large clouds of gas do not emit visible light on their own and are so cold that they cannot be detected by conventional methods. However, Wang and his team think that they are one step closer to detecting gas clouds with their work.
In the studies carried out using the radio telescope named ASKAP in Australia, scientists use the galaxies behind them as 'needles' in order to detect the gas clouds that cannot be detected because they do not emit light and they are very cold. information is obtained. This helps to detect more clouds of cold gas and allows the lost normal matter of our universe to be measured more quickly.
