We are in the last few days of the Decade, and the Decade is quite eventful, especially for black hole lovers. At the beginning of this Decade, no one ever thought that the human species could progress so fast in the study. 

What is a Black hole?

Black holes are nothing but the last stage of stars, having the mass more than the Chandrasekhar’s limit. In a very tiny place, the entire mass of the sun concentrates; as a result, the region becomes massively dense. The high density of matter equipped with a huge amount of mass creates a very strong gravitational pull. The gravitational pull is so large that even the photon particles, having an escape velocity of 3,00,000 km/sec, could not escape from that place. As the region does not allow the light particles to escape, one cannot locate them without studying its surroundings.

Imaging a Black hole

Though human beings had a lot of information about the property of the black hole, they never took the image of one. For the first time, on the 10th of April 2019, the event horizon telescope took the photo of it located at the center of the galaxy called Messier 87. The black hole is around 55 million light-years away from our solar system. The telescope recorded a massive amount of data to get the image of it. The development will remain the highlight of the Decade. 

The Confirmation of an Einstein Theory

Around 100 years ago, Albert Einstein proposed the concept of gravitational force, and after so many years, scientists proved the concept right in 2015. According to Einstein, the acceleration of big masses create disturbances in the space-time fabric, which creates huge ripples- also known as gravitational waves. 

Apart from these two major advancements, there are hundreds of other observations, studies, and hypothesis carried out during this Decade. Overall, the Decade is magnificent for the study of a black hole, and we expect even more in the upcoming Decade.
