Black holes
Since the beginning of time people have naturally been determined to explain everything. As long as we have questions, our search for answers will never cease to exist. Our skies hold infinite quandaries and as a result, the pursuit of explanations will be infinite as well. Since its origin, Astronomy speculated heavily upon discovery, and only came to concrete conclusions later with closer examination. Aspects of the skies, which at one time seemed like reasonable explanations are now laughed at as egotistical ventures. Time has shown that as better instrumentation was developed, more accurate understanding was achieved. Now it seems, as we advance on scientific frontiers, the new search of the heavens is to find and explain the phenomenon known as a black hole. My objective is to explain how the concept of a black hole came about, and shed some light (no pun intended) on how black holes are formed and might be tracked down in our more technologically advanced future. Gaining an understanding of a black hole allows for a greater understanding of the concept of space, time and maybe give us a grasp of both science fiction and science fact. A black hole is probably one of the most misunderstood ideas among people outside of the
Passing the event horizon could send you on that fantastical trip. Some think there would be enough gravitational force to possible warp you to an end of the universe or possibly to a completely different one. The theories about what could lie beyond a black hole are endless. The real quest is to first find one. So the question remains, do they exist? Black holes exist, unfortunately for the scientific community, their life is restricted to formulas and super computers. The scientific community is relentless in their quest to build a better means of tracking. Already the advances of hyper-sensitive equipment is showing some good signs, and the accuracy will only get better. astronomical and physical communities. Before an understanding of how it is formed can take place, a bit of an introduction to stars is necessary. This will illustrate the black hole philosophy. A star is an enormous fireball, fueled by a nuclear reaction at its core. This produces massive amounts of heat and pressure. It is formed when two or more massive gaseous clouds come together which forms the core. Due to that impact, of huge amounts of energy from the two clouds form a conversion. The clouds come together with a great enough force, that a nuclear reaction develops. This type of energy is created by fusion, when the atoms are forced together to form a new one. In turn heat, in an excess of millions of degrees Fahrenheit, are produced. This activity goes on for ages until the point at which the nuclear fuel is exhausted. For the entire life of the star, the nuclear reaction at its core produced an enormous outward force. Interestingly enough, gravity, with an exactly equal force, was pushing inward toward the center. The equilibrium of the two forces allowed the star to maintain its shape and not break away, nor collapse. Eventually, the fuel for the star runs out, and at this point, the outward force is overpowered by the gravitational force. The object caves in on itself. This is a enormous implosion. Depending on the original and final mass of the star, several things might occur. A usual result of such an implosion is a star known as a white dwarf. This star has been pressed together to form a much more massive object. It is said that a teaspoon of matter off a white dwarf would weigh 2-4 tons. Upon the first discovery of a white dwarf, a debate arose as to how far a star can collapse. And in the 1920’s two leading astrophysicists, Subrahmanyan Chandrasekgar and Sir Arthur Eddington came up with different conclusions. Chandrasekhar looked at the relations of mass to radius of the star, and concluded an upper limit beyond which collapse would result in something called a neutron star. This limit of 1.4 solar masses was an accurate measurement and in 1983, the Nobel committee recognized his work and awarded him their prize in Physics. The white dwarf is massive, but not as massive as the next order of imploded star known as a neutron star. Often as the nuclear fuel is burned out, the star will begin to shed its matter in an explosion called a supernova. When this occurs the star loses an enormous amount of mass, but that which is left behind, if
