The world of astronomy is excited. Scientists have discovered “galactic bubbles,” large cosmic structures thought to be fossils left over from the “Big Bang.” An international team of astronomers reports a new discovery. That might revolutionize our entire understanding of cosmology. That’s the discovery. The first “Bubble of Galaxies” is an unimaginably gigantic cosmic structure with a diameter of over one billion light years. and is believed to be the fossil remains left following the “Big Bang” or the huge explosion that caused the universe to be born. Scientists develop new energy source To be able to live on the moon Chandrayaan-3, the lunar probe that makes India’s dreams come true What is the “South Pole of the Moon”? Why must powerful nations send spacecraft to explore? The team of scientists who discovered it stated that This space bubble is 10,000 times wider than the Milky Way galaxy in which we live. Callan Howlett from the Faculty of Mathematics and Physics University of Queensland One of the team members who found it said: “This amazing bubble is a fossil from the Big Bang, 13 billion years ago. When the universe was born…we weren’t even looking for it. But this structure is so large that it overwhelms the edge of the sky we are analyzing,” he said, adding, “It dwarfs many of the largest structures we know, such as the Sloan Great Wall. And the Boots cluster of galaxies is actually just one part of this bubble… What’s even more unbelievable is that It’s right behind our house.” This galactic bubble is centered regarding 820 million light-years from our galaxy, which is very close to our Milky Way galaxy. Howlett said. This discovery provides a clearer picture of the universe’s expansion rate. And this discovery might revolutionize cosmology. “Our analysis suggests that This is because the bubble is larger than expected. The universe is therefore likely to expand beyond what was initially predicted… We are now one step closer to a major change in the field of cosmology. The entire model of the universe may need to be re-evaluated,” Howlett said. The discovery also confirms a phenomenon first proposed in the 1970s by Canadian-American cosmologist Jim Peebles. and winner of the Nobel Prize in Physics which theorizes that In the ancient universe which at that time had the appearance of hot plasma The turbulence of gravity and radiation produce so-called sound waves. “Baryon acoustic oscillation” (BAO), when sound waves ripple through plasma. They create bubbles. Until regarding 380,000 years following the Big Bang This process stops when the universe cools. The bubbles formed by BAO then grew larger as the universe expanded. Similar to other fossils formed following the Big Bang, astronomers previously detected signs of BAO in 2005 when looking at data from nearby galaxies. Researchers stated that The newly discovered bubble is a single acoustic baryon oscillation. This was the first time Brent Tully, an astronomer from the University of Hawaii, was found.
