The idea of a black hole is not one that a lot of people are familiar with. It is not surprising to ask the average Joe on the street what he knows about the black hole, and he will stare at you like you are speaking a strange language. However, there are equally a sizeable number of individuals that have some knowledge of black hole concept. In this write-up, we will be discussing the science behind black hole concept. The principal aim of this article is to give a general guide to the theory.
- Definition: Black hole is a place in space where the force of gravity is unyielding that light penetration is not possible. The reason why the strength of gravity is adamant in such a place is due to the matter that is condensed into a small area. It is brought about mostly by the dying of a star. These holes are not visible to the human eye because of the absence of light in the area. They are only seen with the help of special telescopes used for viewing space.
- The size of black holes: Black holes have no fixed size. The smallest among them is about the size of an atom. Their small size is compensated with their weight which is close to that of a big mountain. There is a particular type of black hole that its weight is 20 times greater than that of the sun. It is called a “Stellar” black hole. There are several of these stellar black holes within the galaxy of the earth. The bigger holes are known as “Supermassive.” The combined weight of these more major black holes is more than that of a million suns combined in one place. There is scientific evidence that each galaxy has at least one supermassive black hole at its center. The black hole located in the middle of our Milky way is known as Sagittarius.
- Formation: It is not exactly clear how black holes came into creation. However, there is a consensus among scientists that they were formed at the same time with the universe. Their formation is brought about by the falling of a large star on itself. The result is what is called a supernova which is the breaking and throwing of part of a star in space.
- Effects on the earth: So far no scientific evidence proves that they pose any danger to the earth. Evidence shows that there is a very vast distance between black holes and the earth and as such, they do not constitute any threat to the earth. So it is safe to say that the earth is in no danger of a black hole covering it one day.
In a Nut Shell
In as much as there are people that have knowledge of the existence of black holes, there are equally a sizeable number of individuals that do not understand what the concept of a black hole is. This article has been able to successfully give a definition of the concept and shed more light on it in a way that someone that has never heard about the concept can easily read it and be enlightened about the idea. It is our belief that we have successfully added to your knowledge about the black hole concept with this article.
