Understanding Black Holes

As the nighttime sky falls upon us and we gaze at the beautiful stars, imagination takes one away from the limits of our solar system to the depths of a high-mass black hole. The universe that we live in contains unique and exciting matter that interests us to learn about all the variances that may only be viewed through a telescope. Within this marvel of wonders, our universe holds a mystery that cannot be defined by modern and classic theories of physics. This mystery happens to be that of the ever clandestine, black hole. Unlike the anatomy of main sequence stars, the black hole has different properties and processes that are generally involved with this interstellar phenomenon. All in all, black hole commonly forms and functions in certain traditions. In addition, black holes influence the intergalactic space as no other known matter does.

To gain a better understanding of the black hole, one must indulge their brain on the subject of how a black hole may come about. All black holes are formed from the gravitational collapse of a star, usually having a great, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. Energy produced by the clouds is so immense that the gases from within begin to nuclear react. The star begins nuclear reaction with universally abundant gas hydrogen. Following hydrogen fusion, the helium element becomes present after the core reaches a certain temperature (Kelvin). Carbon begins to bond as helium fusion is complete from core to surface. Star’s lifespan may exceed millions or even billions of years due to nuclear fusion. The star’s enduring conflict among gravity versus pressure and rotation prevents collapse. The gravitational pull from the core of the star is equal to the gravitational pull of the gases forming a type of orbit; however, when this equality is challenged, the star evolves through different stages. Usually if the star is minute in mass, most of the gases will be consumed while a percentage escapes. This occurs because a lack of tremendous gravitational pull upon those gases, and, therefore, the star loses energy and becomes smaller. It is then referred to as a White Dwarf. If the star was to have a larger mass, however, then it may possibly be a Supernova; hence, the nuclear synthesis within the star merely loses control causing the star to explode violently. After exploding, a fraction of the star becomes absent (if it has not turned into interstellar gas), and the remaining of the leftover supernova is known as a neutron star. Becoming a black hole is the last stage of star evolution in some stars. If the core of the star is so massive (approximately 6-8 solar masses), then it is of greater probability that when the star's gases are almost consumed, those gases will collapse inward and will be forced into the core by the...

However, when Einstein opened the door, black holes suddenly became a possibility, and it took a better half of a century before their existence could be proven, let alone monitored. Now, we have a better understanding of what black holes are, and how they come to be. Black holes are believed

Sizable leaps in our understanding about the mechanisms of life and our universe are in the process of being made with scientists believing black holes are the major precipice to these greater understandings. Black holes push and break many modern understandings of physics and time with many mysterious qualities

As, black holes loses some portion of their mass over a long period of time, it is possible that when they lose all their mass through hawking radiation can collapse into a infinitesimal point and explode to give birth to an another universe or another big bang. This will also support the idea of wormholes as a passage from one

Cosmologists called them quasars, for lack of a better term. They appeared to be quite small, but illuminated the universe around them. To make a long story short, they turned out to be feeding, black holes. Feeding black holes? Black holes eat? What do they eat? Italian food? No, they eat

In a black hole matter collapses and is lost forever but new matter is created in its place. It may therefore be that there was an earlier phase of the universe in which matter collapsed, to be re-created in the big bang (6).R. Hagedorn hypothesized that there is an infinite number of
