Researchers found evidence of the largest explosion in the universe after the Big Bang, `` I do not know why it is so huge ''

The largest explosion after the Big Bang was discovered in a galaxy in Ophia , about 399 million light-years away from Earth. The explosion was caused by a black hole, but researchers were skeptical of its existence at the time of discovery due to its unprecedented size.

The largest galactic nuclear explosion discovered so far was ` ` MS 0735.6 + 7421 '' reported in 2005, but the energy of the explosion discovered this time was five times that amount .

The possibility of an explosion was shown by Chandra artificial satellite in 2016. Astronomer Norbert Werner and colleagues have found cavities in the hot gas created by the injection of black holes. However, the cavities were so large that it was thought that they required a lot of energy to produce them, so Werner and others initially thought that 'this is not possible'.

However, U.S. Navy Research Institute Simona Giacintucci and the International Radio Astronomy Research Center Melanie Johnston-Hollitt, who recently announced their research, have announced that a massive explosion has actually occurred at the center of the galaxy. 'We've seen explosions happening in the center of the galaxy, but this explosion is really, really huge. I don't know why it's so huge,' said Johnston-Hollitt. I am.

According to Johnston-Hollitt, the explosion occurred 'slowly like slow motion' and could take up to one million years. 'The explosion resembles the eruption of Mount St. Helens in 1980, which opened a large hole in the summit. The difference is that the explosion created 15 hot milky galaxies in the cavities created by hot gas. That's the thing. '

'I was really happy when I saw these results.We showed in a paper that there could be a record-breaking black hole explosion in the future,' said Werner, the founder of the cavity. But thought it was unlikely. '' Extraordinary assertions require extraordinary evidence. The observational study provides evidence that we lacked '.

The study used four telescopes: NASA's Chandra X-ray Observatory, the European Space Agency (ESA) 's XMM-Newton , the Australian Murchison Widefield Array (MWA), and the Indian giant metric radio telescope . . Both X-ray data and radio wave data obtained by the Earth telescope helped to confirm the cavity.

Johnston-Hollitt likens his findings to 'the first dinosaur bone discovery.'

'It's a bit like archeology. We were given a 'deep' tool called a low-frequency radio telescope, so we should be able to find more explosions like this one. 'Johnston-Hollitt said, stressing the importance of studying the universe at different wavelengths. Johnston-Hollitt believes that there will be many discoveries following this one.
