Physics of Black Holes Essay -- physics space black holes
Black holes - the strange scientific phenomenon that has astounded physicists and astronomers alike for decades. Popular subjects in accomplishment fiction novels, char holes are one of the greatest enigmas of the scientific world. Even today, the concept of a super-dense ball of matter that not even light evoke escape from is somewhat farfetched, and many scientists disagree with each other about nearly every aspect of a black hole. This project will strain to shed some light on these mysterious formations, and will inform you the reader of the most popular and widely accepted theories surrounding them. Karl Schwarzschild is credited with macrocosm the brilliant astronomer who developed the concept of black holes. In 1916, using Einsteins general theory of relativity, he began to make calculations about the gravity fields of stars. He concluded that if a huge rush, such as a star, were to be concentrated down to the size of an infintessimal point, the effects of Einsteins rela tivity would get really jolly extreme. Schwarzschild doubted that a star could get that small, and theorized that if a star did infact shrink upon itself like that, its gravity would remain the same and the planets revolving around it would remain in the same orbits they ceaselessly had. Since then however, some of Schwarzschilds theories have been disproved, but most of his initial theories hold intact today. The Schwarzschild Radius, the maximum radius a body with a specific mass can have that wont let light escape, is named in his honor, and the equation of which is still in use today Rs=2MG/(c2)In truth, English geologist John Michell was the first to elicit the existence of black holes. He referred to them dark stars and based his calculations on Newt... ...ke for instance the two images below. The first is a two-dimensional representation of the gravity of a mean(prenominal) star. Imagine any object floating through shoes as a marble. Said marble rolling along the flat su rface of the space will roll into the indentation made by the suns gravity. If you flick the marble hard enough, it can roll out of the indentation and roll away. The second photograph is a representation of the gravity made by a black hole. Notice that if the marble rolls into the hole, theres no way it can get out, since there is no end to the hole.Such prospects are intriguing, and provide science fiction novelists with endless material for their writings. None of these theories have been proved, and since we cant get close enough to a black hole to study one, theyre all perfectly valid. Perhaps one day mankind will discover the truths behind black holes.
