INVENTIONS THAT CREATED HUGE CHANGE 🤐

First photo of the massive Black whole-

A black whole is a region of space  where gravity is so strong  that no particles or even  electromagnetic radiation can  such as light  can escape from it .
But, do you know that before 2019 there was no such  image of black whole that proves that black whole exists.But, on April 10, 2019 the first direct image of a black whole and its vicinity was published. This observation was made by an international network of radio telescopes called the Event Horizon Telescope.
By using this telescope  the scientists observed an image of the black whole  at the center of galaxy M87, outlined by emission from hot gas  swirling around it under the influence of strong gravity near its event horizon.
