In the article “Extraordinary Black Hole Found in Neighboring Galaxy” by Sebastian Kamann of the Liverpool John Moores University; Nelson Caldwell, Harvard-Smithsonian Center for Astrophysics; Jay Strader, Michigan State University; Mark den Brok, Leibniz-Institut für Astrophysik Potsdam; Nora Luetzgendorf, European Space Agency; Nadine Neumayer, Max Planck Institüt für Astronomie; and Karina Voggel, Observatoire astronomique de Strasbourg. This article was about a medium-size black hole that was found in our neighboring galaxy Andromeda. This interesting article began with a hunch, however. At first it was thought to be a globular star cluster, a collection of stars bound together tightly by gravity but senior author Anil Seth thought otherwise, he believed that it could possibly be a stripped nucleus (nucleus being the center of a galaxy) instead and he wanted to test this theory but for a while he was turned down. This changed when a black at the center of a stripped nucleus was discovered and Seth began work on the project. They started by finding the how the stars formed they said that ““Globular star clusters basically form at the same time. In contrast, these stripped nuclei can have repeated formation episodes.”” Then they used the distribution of matter within the cluster and used that they determined the speed of the stars. However, the stars at the center of the cluster were moving slower than they should have been. To fix this that they added a black hole at the center the star and once they did that they were moving at their predicted speed. This confirmed that the center of the Andromeda was a stripped nucleus and that there was black hole at the center of the Andromeda galaxy and that is how the discovery was made.

 

This is relevant in our society today because it gives us more information regarding black holes and how they work. This discovery also allows scientists to find medium sized black holes more easily and this is important because it can help us measure black holes more efficiently. It can also help us test the fundamental theories of physics and try to understand them better. The most important thing though is that their are currently no known theories that are universal in physics, therefore black holes allow us to come closer to making universal law of physics which is important to better understanding the world.

 

This article was very well written and strong in that regard, and it had an in-depth and engaging explanation of the events. Furthermore, the article gave me a good understanding the event and why it was important science. The article does need to have a better explanation for why this is important to society and why people not involved in science should be interested in this discovery which is definitely one of its weaknesses. I think would definitely add a better explanation as to why this event matters by saying that it allows us to have a better understanding of the universe. This would show people why this event is important to their lives.
