Its the first real image of a black hole. Until now we have the theory of black hole, cosmological data, artistic picture, black hole stimulation but we are not capable of taking pictures of the black hole and because of that there is a big question mark (?) on the existence of black hole. But that image clear the black hole is not just the blank imagination of us.<\/span> Friends, first we will understand<\/span><\/p>\n \nIn 1915 Einstine Gave The General Theory Of Relativity and says that gravity is not the force but the distortion of space and time <\/b>which is because of mass that means if an object has more mass then it will distort time and space more. Their theory gave the answer of that newton fail to explain which is ” From where gravity arrived”\u00a0 and how it worked But He noticed his Field Equation <\/b>predicting some\u00a0strange object. An Object which has an infinite Gravity and time nearly stops and possibly destroy space and time.\u00a0<\/span> \n(Image Source Google)<\/b><\/p>\n \nMany Scientists Like Stephan hawking predict the different properties of black hole And Begins an Era of debate on Blackhole starts. Because of that appeal began to detect the black hole. But it’s very difficult to detect black because this object has very strong gravity even light cannot escape and as a result, we cannot see them.<\/span><\/p>\n \nWe want to detect Blackhole But hear the question arrives how?<\/b>\u00a0 The theory says that every galaxy has Black Hole In centre In such if we want to detect black hole we have to keep an eye on one of the centres of the galaxy Because blackhole has Strong gravitation we cannot see them directly.<\/span><\/p>\n \n(Image Source Google)<\/b><\/p>\n \nWe can only see through their bright light which is generated in blackhole accretion disc<\/b> that means If we found an object in the galaxy which has a bright light and a black spot in its centre that means its a black hole.<\/span><\/p>\n \nAnyway at first scientists plan was to try to detect black hole which in the centre of our Milkyway galaxy after that they found because of some reasons M87 Blackhole in Virgo constellation was easier to capture.\u00a0<\/span><\/p>\n So scientist decided to first capture the image of M87\u00a0<\/span><\/div>\n \nEvent Horizon telescope xe its not a single telescope but the network of many telescopes located in different parts of the earth which is unique in its own way.<\/span><\/p>\n \nLet’s see how Event Horizon works\u00a0<\/span><\/p>\n \n(Image Source Google)<\/b><\/p>\n \nThe light waves near the black hole are in circular patten just like when you throw a stone in the lake it makes a circular pattern. If light waves came in the same pattern from a black hole it’s not a difficult problem to capture them but the distance between the black hole is so wide that the light waves which are in circular patten when reaches to earth become plane. Which is very difficult to detect them?\u00a0<\/span><\/p>\n \n(Image source google)<\/b><\/p>\n \nBecause of event Horizon telescope is the network of many telescopes, their other every single telescope should synchronize perfectly (without any error)\u00a0 if it’s not then they will not work properly.\u00a0<\/span><\/p>\n \u00a0As we know the event horizon is the mixture of many telescopes. If they are not synchronized perfectly the data collected from the different telescope when they combine they will not get the perfect image of a black hole.<\/span><\/span><\/h4>\n \nTo ensure that they work together they\u00a0synchronized all the telescope with atomic clock ( atomic clock get the difference of 1 sec in every 100 million years)\u00a0<\/b><\/span><\/p>\n \nBecause all data are in petabytes they cannot share through the internet so they stored in hard drives and after that, they transfer all data into a supercomputer and reconstruct the image.<\/span><\/p>\n \nAfter the image was ready, to ensure the image they send all data in different scientist and told them to reconstruct image without showing the real image.<\/span><\/p>\n \nThen they collect all data from different scientist all over the world. When they saw the image the get into a celebration all image are exactly the same as theirs.<\/span><\/p>\n \nAnd then they declare the real image of Black Hole.<\/span><\/p>\n \nExternal Links<\/span><\/p>\n \n——————————————————————————————————-<\/p>\n<\/div>\n<\/div>\n<\/span>

\nThis image is of Messier 87 (M87) black hole which is 55 million light-years away from earth in the centre of Virgo constellation. This is image is mostly the same as Astronomer predicted and also prove Einstein general theory of relativity.<\/span>
