Astronomers have just found the location of the material part that is often "missing" in the universe - a mystery that has existed for decades. According to the announcement, the research team used radio waves emitted from 69 extremely powerful radio explosions in space to accurately locate the missing material.
In the universe, matter exists in two forms: Dark matter - invisible, only absorbed through attractive effects - and everyday matter, including gas, dust, stars, planets and everything familiar such as Earth or humans. However, scientists have previously only identified half of the total amount of matter in the universe, the rest is unknown.
We wondered, where is that substance hidden? said Liam Connor, a professor of astronomy at Harvard University and lead author of the study. The answer is: In a fog-like network stretching among the galaxies.
Most of the missing matter is found in thin air that is sparse among galaxies, known as the inter galaxy environment. Smaller regions are located in the air regions surrounding galaxies, including the Milky Way, and the rest are concentrated in galaxies, mainly in star or gas form.
Physical matter is often made up of baryon - lower-atteratter particles such as protons and neutron, which are the foundation for the formation of atoms. Connor emphasized: We know exactly what kind of material is. We just don't know where it is."
So what causes most of the material to drift away from the Galaxy? The answer lies in super tanlar explosions or the activity of super black holes. These phenomena can push a large mass of gas out of the Galaxy, pushing them so far away that they cannot be observed by conventional methods. This air does not exist in a normal state but exists as plasma, with protons and electrons separated.
To discover this substance, scientists relied on a phenomenon called fast radio bursts (FRBs) - strong radio waves from distant points in the universe. When these waves transmit to Earth, they are scattered through multiple waves, and the level of diffusion depends on the amount of matter they travel. This allows for accurate measurement of invisible matter.
Now, scientists have identified the distribution of matter in general: About 76% in space between galaxies, 15% in the gas regions surrounding galaxies, and 9% inside the galaxies. We can now move to a bigger mystery: What is the nature of dark matter and why is it so difficult to measure?
