![]() ![]() This phenomenon is called the Accretion disk. And because of this force gas and particles close or nearby the black hole start to gain a rotational speed being forcibly attracted into the black hole. This spacetime deform creates a gravitational acceleration force pointing to the center of the dense mass body. This super mass star is squeezed into a very small space because of gravity and to form the black hole that compact mass can deform spacetime, according to the theory of general relativity. The mass is a very important factor to decide if the dead star is going to turn into a black hole or a neutron star. ![]() In theory, black holes are formed usually when a very massive star much heavier than the sun collapses, at the end of Its life. Is like try to see a black object in a black background, you cannot see, or if you do, is very hard. The interesting part here is that if even the light cannot break free from this force, is impossible to see a black hole or even to known where is one. With that said, we can get the definition of a black hole.īlack Hole is a spacetime region where the gravity is so but soooooo STRONG that any gas, dust, particle or even the light can’t break free from it! They are all STRONGLY attracted through the gravity force into the black hole and disappearing, going to a place that remains unknown even today for the scientist. An interesting fact is that a single point in this coordinate system is called an event. ![]() Spacetime is a four dimension manifold, three dimensions of space and one dimension of time, in a coordinate system we would have (x,y,z,t). The first thing we need to know is a concept used a lot in many topics in the astronomy field, which is the notion of what is spacetime. Penrose through impressive mathematical methods proved that black roles are connect to the Einstein’s theory of relativity while Reinhard Genzel and Andrea Ghez work’s found out irrefutable proves that are indeed a black hole in the center of our Milky Way galaxy, today know by the name Sagittarius A*.įor us to fully understand the theme, we need to know a few basic concepts about black holes, like “What is a black hole?” “How are they made of? Where we can find one?” They are all amazing researchers and we would love to talk about each one of them in here, but today for a better explanation and understanding of the context of the first black hole picture we are going to talk about the work of the Laureates Roger Penrose, Reinhard Genzel and Andrea Ghez, the winners of the Nobel Prize in Physics.Īccording to the official website of the Nobel Prize, the laureates were acknowledged “for the discovery that black hole formation is a robust prediction of the general theory of relativity” and “for the discovery of a supermassive compact object at the center of our galaxy”. Recently we saw twelve laureates be awarded with the 2020 Nobel Prize, and how one of them contributed remarkably to humankind with their research and discoveries. The universe is getting more enlightened each with new information and because of that we are capable of better understanding all the mysteries beyond our planet. This picture was the first step towards a new door of information. The picture was amazing news not only for the astronomy field but also for the whole world. ![]() You probably heard the news about the first black hole picture posted by the scientist. ![]()
