Earthquake in science: Scientists have discovered half of the universe

Science Earthquake: Scientists have discovered the hidden half of the universe: April 18, 2025, 20:36 IST Science News in Hindi: Scientists have discovered ‘missing cosmic material’. It was hidden in large halo outside the galaxies in the form of hydrogen gas. This new discovery will help understand Galaxy and Black Hole.

Scientists found out by using the ‘cosmic microwave background’. Look for the enormous clouds of hydrogen hidden around the galaxies. New -delhi: Half of the universe was finally found. No, we’re not talking about theft. This is the story of that ‘missing’ matter, after which scientists have been searching for decades. It is now learned that he was around us, but was hidden from sight. This part is ‘baronic matter’, that is, the goods from which stars, planets, people … are all made. Scientists feared that about 50% of it was missing somewhere. Now it has a look at it, outside the galaxy, as invisible hydrogen. It was impossible to see this hydrogen. It is in ionic condition, so spread and light that no telescope can catch it. But it is still discovered. How? For this, scientists did not see the air straight, but saw the light behind the sky. The cosmic microwave background (CMB), ie the ‘first light’ of the universe is spread in each direction. If this light clashes with a gas, there is a slight change. It wasn’t easy to catch that change. But scientists have placed a trick called ‘stack’. That is, millions of people have been seen collecting one above one. As a result, it faded and invisible gas began to glow. And our lost hydrogen was seen there! How did it reach there? Researchers at the University of California and Lawrence Berkeley Lab studied 1 million red galaxy from 8 billion light years away. They found that there is a large hydrogen cloud around each galaxy. As great, as did not think before. Now the question arises that how has this guest achieved there? Two ways. One guest comes from outside the galaxy and is included in it. Second- If the black hole is active in the middle of the galaxy, it leaves such a quick force that the gas pushes out of the galaxy. This gas then covers the galaxy. Hydrogen can shine in space. This is the case in Orion Nebula, but there is not enough density and radiation to shine in free space. (NASA, ESA, M. Robberto (STSCI/ESA) and Hubble Space Telescope Orion Treasury Project Team) What came from Black Hole? If the black hole is more active, the jets have come from its magnetic field to millions of light years away. Very strong winds also burst out, excluding the gas inside. It stops to become stars because stars are made of gas. Now the enormous hydrogen clouds have been found, they say that this activity of black hole is probably occasionally separate. Sometimes calm down, sometimes suddenly flaring. It gives new light on how galaxy is formed, how it grows. But the story doesn’t end here. Some research suggests that some more missing matter of the universe in the lines of dark matter is hidden, the same cosmic web connecting the galaxies. An important piece of puzzle of the universe was found, this research opened a new door. Scientists have now found a way to find these invisible gases. The job now is to add all these pieces and make the whole picture. Researchers also wrote in their study: “This work is a new beginning to solve the universe of the universe.” His study was submitted in physical review letters and is available on Arxiv.
