Extract of sample "Black Holes"

Download file to see previous pages Based on this concept of black hole, scientists have tried to describe unseen surface of the black hole as ‘event sphere’ that at a conflict, does not allow any particle or object to return and thus scientists explain event sphere as the point of no return. The scientists named black hole as black because of its properties that mainly include absorbing everything that comes into its reach resulting in everything disappearing, thus black. Quantum physics and mechanics have contributed significantly in understanding of black holes that indicate that although black holes absorb everything that comes in its reach, however, there have been observations of a very weak emission from the black holes that has a temperature, which is inversely proportional to the mass of the black hole (Taylor & Wheeler, 2000).
Scientists believe that every galaxy has these black holes at their cores, which absorb all the left-out energies of these galaxies and thus they are denser and heavier than even the sun, which is a theoretical assumption and thus, has been criticised by many experts in the field who even do not believe in the existence of black holes. However, scientists who believe in black holes indicate that with their characteristic of absorbing everything, the black hole creates a spinning disk that confine nearby particles in the space. Few scientists have been successful in observing this accumulation-spinning disk on radio, x-ray, and gamma ray bands since emissions of black holes often become very warm and thus, come on the x-ray bands (Susskind & Lindesay, 2004). With these observations, a huge number of scientists have now proofs of real black hole at the core of Milky Way galaxy that is heavier than the four million solar masses, and it is assumed that this black hole has maintained its gravitational field and absorbing everything that comes in its vicinity.

The Role of Black Holes in the centers of Galaxies

...observation. In the Milky Way, the supermassive black hole is known as Sagitarrius A*, which is read as “A-star” (Naeye & Gutro, 2008). Sagitarrius A* is known to be “27,000 light years from the Earth [and] is four million times bigger than the Sun” (Ghosh, 2012). However, NASA reports Sagitarrius A* to be 26,000 light years away from the Earth, and not 27,000 (“A Mystery,” 2002). In fact, the existence of black holes has long been theorized by British astronomer Sir Martin Rees in 1974 and, according to him, “Supermassive black holes [or] ones with a million or even a billion solar masses might exist within the centers of some galaxies”...

Black Holes

.... The fundamental question is how do black holes come into existence? Stars go through phases in their life cycle where they convert a healthy supply of hydrogen into helium through a process known as nuclear fusion. This is possible due to the high pressure and temperature that occur in the core of the star. At the end of a star’s life, it begins converting helium into other denser elements. Depending on the size of the star will depend whether a black hole will form. Black holes occur usually with massive stars. What happens is that the star begins to collapse on it, pushing toward a single point on the space-time continuum. Eventually, the star collapses in on itself at a singular point in space, which creates a quantum singularity...

Black Holes and Baby Universes by Steven Hawking

...ations. Hawking writes that "we ought to be telling people about the modern understanding of such basic concepts as space and time" (p.44), explaining that these theories can tell more about the Universe than Newtonian one -- it is the example of logos. He writes that he "has been variously called a nominalist, an instrumentalist, a positivist, a realist" (p.42), but these "ists" don't play role for him -- it is the example of ethos. The author writes that it seems ridiculous that "the speed of light was always the same no matter how the source of the observer was moving" (p.43) -- it is the example of pathos.

Film Analysis-Holes

The Warden assigns the daily chore of digging holes five feet deep, in the dry lake on a daily basis. She dominates everyone involved in the camp, inflicting pain on the assistant warden and threatening the patient counselor, Pendanski. It is evident that she is in control of her surroundings and those she interacts with. The empty lipstick tube with the initials KB, found by one of the boys during their daily digging of the holes, appears to hold special meaning for the warden. After the tube is brought to her, the warden becomes seemingly more powerful, inflicting her wounds and passing judgment on the others, with the exception of Stanley. The lipstick tube represents feminine control, power and intuition. The tube bears the in...

The Black Holes

... where the neutron star is extremely large, the 0forces of gravity outweigh the pressure gradient and this leads to a collapse. Such a neutron star collapses and shrinks until it finally turns out into a black hole. On such a scientific basis, this paper seeks to explain the properties, concepts, and space-time phenomena underpinning concept of the black hole formation. There are different types of black holes. The most common ones are; charged, rotating, supermassive, and static (Schwarzschild 150). Importantly, these four types of black holes are made up of the same fundamental elements; the singularity, the photon sphere, and the event horizon. However, the rotating black hole has an ergosphere which is a combination of two...

Astronomy - Black Holes

... Task Astronomy - Black Holes Introduction A black hole can be related to a vacuum cleaner machine because of it cleans the galaxy by absorbing materials passing in the space, a function similar to a vacuum cleaner’s role. This is because of the superbly strong gravity force they possess (Melia, 94). For example, astronomers recently observed a black hole swallowing a star that was wandering near it in the space, which is prevalently known as the stellar homicides. In this essay, what black holes are, how they are formed and observed, the theory and astronomy of black holes are critically discussed. What they are A black hole is a section in the space-time that traps everything passing across the area because of its exceptionally strong...

Black Holes (Astronomy)

... Black Hole: Explanation of the Mystery A black hole is a region of space which is astonishingly so dense thatit does not allow anything to escape from its surface, even the photons of light. However the black holes do not have any additional gravitational acceleration, their high gravity is by virtue of their extremely high mass. For example if a star like our sun changes into a black hole, this will not affect the motion of planets revolving around it, each planet will continue to follow the same orbital path however the amount of light and heat received from the star will certainly be changed because a black hole is formed when a star runs out of its nuclear fuel. This means that the general perception that if the sun runs out of its...

This essay will explore the concept of black holes, that is, all that is currently known about this phenomenon, how they are formed, and what can be learnt from them; similarly, this essay will also highlight how black holes are detected and how they are made. Conceptualizing black holes The appearance of an event horizon, the boundary in space-time through which matter and light are attracted inwards towards the mass of the black hole becoming trapped permanently, is the most...

How Black Holes Work

... earth and space, can only detect these black holes. Despite exhibiting dangerous properties, black holes do not cause any major threat to earth and its people. Black holes are formed when star undergoes destruction, although not all stars destroy themselves. “While most stars end up as white dwarfs or neutron stars, black holes are the last evolutionary stage in the lifetimes of enormous stars that had been at least 10 or 15 times as massive as our own sun” [1]. The fact is that because of the massiveness of these stars and the resultant presence of vast gas in it, intense gravitational field normally builds up and tries to collapse the star. In a way, it can be said that increased fusion reactions...
