How Can We Predict What Happens at an Event Horizon?

Every galaxy seems to have a supermassive black hole in its center. A black hole is defined as such because nothing can escape from a certain point inside, not even light. There is, however, a last stable orbit which is called the event horizon outside of which gas can still radiate away. This event horizon might be the key to understanding black holes and, therefore, observers are interested in resolving the event horizon to see what happens at it. As ANDREAS BURKERT explains in this video, his theoretical research group develops computational models based on the system of meteorologists to predict how a gas cloud would behave at the event horizon and in what time frame. They then check back with the observers and correct the models accordingly. These computational models thus assist the observers in understanding the events they see. This contributes to a better knowledge of black holes and, eventually, an increased understanding of the universe.
