Since the 18th century, scientists have speculated about the possibility that some objects have a gravitational field so strong that even light cannot escape them. In 1915, Albert Einstein published the General Theory of Relativity, a geometric theory for gravity. The following year, Karl Schwarzschild obtained results for Einstein's equations of relativity, mathematically demonstrating that the idea was possible. Throughout the 20th century, theoretical knowledge has been improving. Indirect measurements of black holes were made by observing the abnormal behavior of other bodies and materials in the vicinity of suspicious locations in space.
It was not until April 10, 2019 that humanity could, for the first time, directly observe a black hole. The Event Horizon Telescope (EHT) project used several radio telescopes scattered throughout the planet and took advantage of the rotation itself to capture a large amount of light (very faint and very distant). It was emitted by material falling into the black hole at the center of the Messier 87 galaxy.
Transforming the enormous amount of data obtained by several different telescopes into a single visible image was a major technological feat. It required very advanced computational techniques. The team responsible for this feat was led by a young engineer named Katie Bouman.Bouman began his studies in image processing in high school, participating in research in the area at Purdue University. She was a distinguished student in the electrical engineering course at the University of Michigan, earned her master's and doctoral degrees in electrical engineering and computer science from MIT. His doctoral thesis was precisely about techniques for capturing images of black holes.
