People always wonder what happens when one jumps into a black hole and reckon with how it feels for the first time for a person to be close to one. A simple rejoinder should leave the impression that one’s body would be elongated given the strongest pulls on both ends, pulling the head and the toe. Therefore, a black hole describes a region in the space where gravity is felt the strongest that nothing can escape from it. Sundermier’s (2016) offers a succinct explanation about black holes, fully describing the physics that support their existence and their perceived implication to scientist regarding the concepts of relativity and gravitational fields.
Summary of the Article
The article commences by clearing doubts on the existence of black holes, affirming their actuality, and considers them available in nearly every galaxy. Sundermier (2016) also outlines the historical aspects of the black hole and considers Newton’s discovery of the gravitational force as an important milestone in the study of black holes. Additionally, the article recognizes several other scientists among them physicist Karl Schwarzchild, Albert Einstein, French scientist and mathematician Pierre Simon de Leplace, and Reverend John Michell, to mention but a few.

Sundermier (2016) equally explains how black holes are formed attributing the formation of a black hole to a star’s inability to stop compression of matter around it. Also, the study supposes that black holes can be formed when massive stars collapse, save for those that were formed following the big bang. Interestingly, the article submits that there is no limit to how immense black hole can be, noting that black holes can be as big as the earth and a billion more times than the actual mass of the sun.
Most importantly, the article explicates on Einstein’s law of relativity, which posits that the speed of light in a vacuum is independent of the motion of observers. Additionally, Sundermier (2016) explains gravity and describes how all objects with mass have to submit to the law, with the force felt more by objects with larger masses than those with a small mass. The article bases on the foregoing realization to surmise that objects can be pulled towards a black hole if they move close enough to interfere with the surrounding cosmic microwave background that holds a star in position and a compact state.
Criticism and Questions about Physical Properties of Black Holes
It is commendable how the article expounds on the topic of black holes. The findings of the article are interesting as they are insightful. Sundermier (2016) underlines that black holes have three physical properties, which include mass, charge, and rotation. The confirmation by Sundermier confirms that a black hole is a sphere surrounding the black hole and not a physical object as imagined by many. However, most scholars disagree on the exact characteristics of black, given that the research is incomplete. For instance, ( Sasaki, Suyama, Tanaka, and Yokoyama (2018 ) confirm that black holes are of four types and their composition defines their properties. Consequently, it would be faulty for Sundermier (2016) to group all black holes as one component that displays the same characteristics. Even though the article seemed detailed, Sundermier (2016) could have expanded more on the different types of black holes, to give his audience a better understanding of the topic and inspire them to conduct further research on the subject.
Conclusion
In summary, the article by Sundermier (2016) is well written and provides a background overview of the subject. The article addresses key concerns about the formulation process of black holes, their properties, and their characteristics. Additionally, the study sorts through several works by notable scientists, highlighting their contribution and possible gaps in their explanation. Whereas the article describes the formation process of a black hole, it ignores an equally important detail that categorizes black holes into four different objects. Therefore, a revision of the study should be expanded to include such missing information to adequately serve its purpose.
