Black holes – the most mysterious celestial object may be much more homicidal than scientists assumed it before, revealed a new study.
Since centuries, black holes have been intriguing scientists across the world. Black hole – a celestial province that exhibits extremely intense gravitational effects that can grab every passing-by matter, including stars, particles, electromagnetic radiation, light and much more. Earlier, scientists have somehow confirmed that black holes consume nearby stars for expanding its masses, but the new theory has alleged the black holes much more murderous than it previously thought to be.
According to the General Relativity Theory, prescribed by Albert Einstein in 1915, the formation of black holes takes place from the violent collision of two dying stars. Once a black hole formed, it continues to expand by fascinating accumulation from its surroundings. Black holes, by absorbing other nearby stars and integrating them with other black holes, turn into supermassive black holes, which might range more than of millions of solar masses.
According to a new research paper, published on Monday, Supermassive black holes pull apart and gulp down the nearby ill-fated stars a hundred times more frequently than the earlier prescribed statistics. As per the previously established hypothesis, such cosmic cannibalism – supermassive black holes eating stars hundred times more often was extremely uncommon and used to take place once in every 10,000 to 100,000 years for each galaxy.
But the new study, conducted by an international team of astronomers at the University of Sheffield has highlighted that, supermassive black holes are millions to billions of times more enormous than the mass of our Sun, and they used to rip up and consume stars in a more hundredfold manner than it previously thought.
According to James Mullaney, an astronomer at the University of Sheffield and the co-author of the study, “Our recent surprising breakthrough show that when two galaxies run into each other, the event dramatically accelerates the ripping up of black holes, resulting in a faster break and swallow of stars.”
For the findings, an astronomer team co-led by astronomer Clive Tadhunter and James Mullaney, both from the University of Sheffield, examined 15 colliding galaxies, each housing multi-billions of stars. In the breakthrough, scientists have verified that each galaxy has a black hole in its centre. But how, the black holes form in the core of the galaxy is still a matter of question.
