Info. Black holes are extraordinarily dense entities formed when very massive stars collapse at the end of their life cycle. According to Albert Einstein’s theory of general relativity, black holes are uninhabitable chasms of spacetime that end in a ‘singularity,’ or a mass of infinite density. Black holes were predicted by the Einstein's theory of general relativity, which showed that when a massive star dies, it leaves behind a small, dense remnant core.

At the center of most galaxies, there’s a massive black hole that can have mass of millions or even billions of Suns that accrete gas, dust, and stellar debris around it. The Black Hole Tragedy is an important incident in the history of India that took place at Fort William in Calcutta in the year 1756. The year 2020 was the joint hottest year on record globally along with 2016, according to European Union’s Copernicus Climate Change Service (C3S). Primordial black holes are a hypothetical type of black hole that formed soon after the Big Bang. … It is hypothesized that these black holes were created at the beginning of cosmic expansion as little “imperfections” in the fabric of space-time. Your email address will not be published. Should the hypothesis by the researchers turn out to be true, it would mean a major breakthrough in astronomy. The black hole has a mass of 6.5 billion Suns. Every large galaxy in the universe has a supermassive black hole at its centre, whose mass is millions or billions of times that of the Sun, The black hole at the centre of our galaxy– the Milky Way– is called Sagittarius A*, and is 26,000 light-years away from Earth, As per the theory of gravitational waves, during such a merger, when the amount of waves generated in one direction is stronger than another, the new big black hole can be sent away from the centre of the galaxy into the opposite direction, So far, though, scientists are yet to find definitive evidence for recoiling black holes.
