![]() ![]() Stellar Black Holes are Formed by Dying Stars ![]() Years before that, British polymath John Michell predicted the presence of so massive or so dense ‘dark stars,’ that they could exhibit gravitational forces so strong that not even light could escape and until 1967, black holes did not get their universal name. A term called the Schwarzschild radius has come from Schwarzschild ‘s work, a measure of how small you would have to compact any object to create a black hole. Karl achieved this the same year as, in 1915, Einstein published his theory of general relativity. Instead, Karl Schwarzschild was the first to use the groundbreaking equations of Einstein, and to prove that black holes could indeed form. No, Einstein did not discover the existence of black holes-although his relativity theory predicts their formation. For example, The European Space Agency claims that it is four million times as large as our Sun and that it is surrounded by incredibly hot air. We are around two-thirds of the way out of the core, compared to the rest of our galaxy, but we can definitely see its impact from afar. Fortunately, we are nowhere near this monster. Perhaps our Milky Way has a Black HoleĪnother question is, given how dangerous a black hole is for Earth to be swallowed in any imminent danger? The response is no, astronomers say, but a large supermassive black hole lurking in the centre of our galaxy is likely to be present. Companion stars in the form of stellar wind shed some of their mass, and the material in that wind then falls into the grip of its hungry neighbour, a black hole. Black holes seem like they suck in matter from all over, but that’s a growing misconception. In fact, it would continue to orbit the black hole as it orbits the Sun today. If you replaced the Sun with an equally massive black hole, Earth would not be sucked in. ![]() Some people think that black holes are like cosmic vacuums that suck in the space next to them when black holes are, in fact, like any other object in space, though with a very strong gravity field. When the matter starts bleeding toward the black hole from the start, it gets faster, gets hotter and glows brightly in X-rays. The black hole takes the star naturally, then rips it to shreds. For example, say a star gets too close to the black hole. Analyzing a black hole’s surroundings, we can see the impact on its environment. What we can see though, is a black hole’s effects. Black holes Can’t be Seen Directlyīecause of its colour, a black hole is called a black hole, particularly since light cannot escape. Supermassive black holes occur more frequently in the centre of galaxies, and some scientists believe that this type of black hole was formed at the same time as the galaxy was formed. Such black holes may have only evolved over time, or the product of black hole combinations after collisions may be supermassive black holes. Scientists assume that this sort of black hole could be shaped differently from the stellar black holes created by dying stars. The largest kind of black hole is known to be supermassive black holes. Supermassive black holes exist in cores of galaxies and typically hold the equal mass of millions of suns. Stellar-mass black holes are created when massive stars explode, leaving a black hole with only a few suns mass behind it. ![]()
