Essays on Black Hole.

The differences in societal and cultural expectations between men and women are often vast and complicated, and change greatly over time. Literature is a fantastic avenue by which to explore these issues, and the effects they have on women in particular (as women have historically enjoyed fewer rights and agency than men). Charlotte Perkins Gilman’s short story “The Yellow Wallpaper” and Charles Burns’ graphic novel Black Hole, while telling different stories, both have significant things to say regarding how girls and women are socialized into conforming to certain social norms that may not be in their best interests, ...

We Can Remember It for You Wholesale (Phillip K. Dick) – Air Raid (John Varley). ‘We Can Remember It for You Wholesale’ is a futuristic short story written by Phillip K. Dick, centered on the concept of memory manipulation. It takes on the undiscovered fields of new age science. The concepts involved in the short story are so complex and underdeveloped even in this age and time. But still the author immaculately and ostentatiously nails his narrative. In the same sense, ‘Air Raid’ written by John Varley, seems to be the perfect match for the pairing. Both these short stories ...

According to Clark (2012), Astronomers have measured the background light from all the stars in the cosmos and inferred the number of stars created since the dawn of the universe. The operation was performed using NASA’s Fermi Gamma-ray Space Telescope.

Emissions were detected from gamma ray emitting supermassive black holes at the centers

of galaxies to undertake the experiment. The study concluded that the universe has an average of 1.4 stars per 100 billion cubic light-years and first stars were formed when the universe was almost 400 million years old.

Study of stars, their formation and their count has always fascinated astronomers. Study of

stars lie at the heart of Astronomy and drives it in most of the cases. Star formation ...

Question #1

Three main layers of the interior of the Sun are convection zone, radiation zone and the core.The central part of the Sun with a radius of about 150-175 thousand km (ie, 20-25% of the radius of the Sun), in which are thermonuclear reactions, called a solar core. The density of material in the core is about 150 000 kg / m ³ (150 times higher than the density of water and ~ 6.6 times higher than the density of the densest metal on the Earth - osmium), and the temperature in the center of the core is over 14 million K. A ...

- Describe the three main layers of the Sun's interior.

The three main layers of the sun are referred to as photosphere, chromosphere and the corona. According to the text ‘Discovering the Universe’ by Comins, N.F & Kaufmann III, W.J, 8th edition, each of these layers has different features that makes them different from one another.

The photosphere is the layer that appears to be the major part of the sun where visible light comes from. Photosphere is about 400km thick with a lower density when compared to that of earth standards. This part of the sun also has a blackbody spectrum. In terms of the sun's atmosphere, photosphere ...

- Where in the Galaxy is the solar system located? a. in the nucleus, b. in the halo, c. in a spiral arm, d. between two spiral arms) e. in the central bulge

The solar system is placed in a spiral arm, considered the most hospitable region in the galaxy. The spiral arms are where the active stars form and they orbit around the Milky Way galactic center and the solar system joins this orbital trip. According to the latest discoveries, the Milky Way galaxy has only two spiral arms (Scutum – Centaurus and Perseus) as opposed of four previously considered ...

- Where in the Galaxy is the solar system located? a. in the nucleus, b. in the halo, c. in a spiral arm, d. between two spiral arms, e. in the central bulge

Our solar system is located in one of the two major spiral arms of the disk-shaped Milky Way Galaxy. It is not located in the center or nucleus of Galaxy because the supermassive black hole Sagittarius A*, because of its tremendous gravitational force, make it possible for clusters to remain intact. In the halo of a galaxy, there are mostly spherical distribution of globular clusters, dark matters, and isolated stars. If between the two spiral arms, it is tantamount to saying that our Galaxy is at its nucleus. At the central bulge, it is made mainly of gas, dust, and ...

According to (Leong 5), it is a minor spiral arms of the Milky Way galaxy some three thousand five hundred light-years (1100 parsecs) across and approximately ten thousand light years (3100 parsecs) in length. It is also known as local arm, Orion Bridge, local spur and Orion spur.

It is named for the Orion constellation, one of the prominent constellations of the northern hemisphere winter (southern hemisphere) (Leong 26).the brightest stars and numerous famous celestial objects of this constellation- Betelgeuse, Rigel, the stars of the Orion belt, the Orion ...

Question 1

The solar system is situated in the outer reaches of the Milky Way Galaxy. The Milky Way Galaxy is a spiral way and is made up of over two hundred billion stars. The Milky Way Galaxy has many arms which are named for the constellations seen in those directions. Examples of the spiral arms within the Milky Way galaxy include the Sagittarius arm, Centaurus arm, Perseus arm, Cygnus arm and the Orion Spur arm. Our solar system is located in a spiral arm that is called the Orion Spur. The Orion Spur is named after the constellation “Orion the hunter”. The ...

The Solar System is located at the spiral arms of our Galaxy is called the Milky Way. It is basically made of the galactic dick, globular clusters and the halo. Scattered below and above the disk are the globular clusters. They are randomly scattered and they orbit in elliptical orbits. They have little or no gas in them and contain older stars than in the disk. The halo is the dim region that surrounds the whole galaxy. Now, the location of the Solar System is in the galactic disk’s spiral arm. There are six spiral arms arising from ...

Assignment 4

4. Describe the three (3) main layers of the Sun's interior. The three (3) main layers of the Sun’s interior are the Core, Radiation Zone, and Convection Core. First, the Sun’s Core or innermost part, is tightly packed and with a temperature of about 1.5x107 K. It extends from the Sun’s center to the photosphere (that is, approximately 0.25 solar radius or 1.75x105 km). It is at the Sun’s Core that thermonuclear reactions occur because of the enormous temperature and pressures. Second, the Sun’s Radiation Zone or the middle interior part, where energy ...

Q1. Describe the three main layers of the Sun’s interior.

The three main layers of the Sun’s interior are the core, the radiative envelope and the connective envelope.

The core is the center of the Sun, with a density of 150 g/cc and a temperature of 15 million K. This is the region where high energy fusion reactions take place and energy is produced. The energy produced is mainly in the form neutrino and gamma rays, which are actually high energy protons which travel several light years and supply energy to the Earth and other planets. The energy produced in the core then radiates outwards through the radiative zone. The ...

It depends on what the business is trying to accomplish that decides which strategy to use. The businesses have to think about what their customer wants or needs and how their competitors are reacting to the situation. Timing is another important factor. Whatever strategy – all need creativity. An ability to design a practical strategy is crucial to reaching the business goals due to the competition that now exists. Therefore the manager must understand and use well the assets the company has as resources. Strategy means setting up the process that will best reach the goals effectively and efficiently; clearly ...

The variability of stars existing within our universe represents diversity and uniqueness. Humanity may not observe the whole life of a single star, however, techniques have been proposed to study the stars. We have different ways how to measure a star's temperature, age, and mass even, even though it seems impossible. The said variability of stars is key to the measurement of a star's characteristics. The existence of variable stars suggests that stars change on a time interval, unfortunately, too long humanity cannot observe. Nevertheless, humanity have developed a way of understanding the stars through their variability. Needless to say, variability provides unique ...

“Psycho” is one of the most horrifying movies by Alfred Hitchcock. Although there were no grandiose shots, Hitchcock was able to invoke horror and thrill among the audience because of how he presented the crime scene and how he provided close ups of the victims. The black and white screen adds more horrifying effect and delivers an eerie atmosphere. Hitchcock introduces the viewers to the film’s characters and invites them to enter their world through consistent close up shots. By doing so, the audience establishes a much closer contact with the character and they seem to observe his/her experience ...

The universe is a collection of different galaxies; stars and planets and earth is part of it. The earth is also one of the planets in the solar system comprising the sun and nine other planets. The central part of the solar system is the sun while the earth and other planets in the solar system revolve around it. The earth as a gigantic structure but in the actual sense, it is infinitesimal in comparison with the solar universe. The universe has many galaxies, and the Milky Way galaxy is one of that many galaxies in the universe. The name "Milky ...

Introduction

A black hole is a region in space-time, the gravitational attraction which is so large that it can not leave even objects moving at the speed of light, including photons of light itself. The boundary of this region is called the event horizon, and its characteristic dimension - the gravitational radius. In the simplest case of a spherically symmetric black hole Schwarzschild radius is equal to it. Theoretically, the possible existence of such regions of space-time should be of some exact solutions of Einstein's equations, the first of which was obtained by Karl Schwarzschild in 1915. The exact inventor of ...

Introduction

When the first crude telescopes grazed the vast space, the 17th century and astronomers such as Kepler and Galileo was already making discoveries of such as the moon craters, the rings of the planet Saturn, and the giant planet Jupiter. These discoveries paved the way for a more extensive exploration of the cosmos, which was ultimately revolutionized by the birth of the Hubble telescope. In April 1990, word’s most advanced space telescope named after the astronomer Edwin P. Hubble was launched at 353 miles above the earth’s surface with a mission to see deeper into space and beyond. The ...

Looking up to the sky has been one of the most important activities of humans. Early civilizations are finding answers to their theological principles in the stars while others look guidance as they travel (Rosenburg & Russo, np). Astronomy is a vital part for the foundation of the religious beliefs and concepts of most of the early civilization. They view astronomy as a tool or as a backbone to their religious, social and cultural beliefs (Sprajc 87). Curiosity and hunger for knowledge have been the fuel for mankind to search answers in space. The significance of astronomy to life could be hard to ...

Interstellar: Film Cuts

For those who have seen Interstellar it is a cinematic adventure only matched by the amount of plot holes found throughout its story. The viewer is taken on a whirlwind celestial journey through space, and time, as relativity and our imaginations are warped. There is so much happening in the 2:49:00 movie, small cinematic gestures, such as film cuts, got lost in the grandeur. However, several scenes with three in particular, allowed film cuts to be noticed for the tools they are. Well into the film, after the explorers had landed on their first planet, an ‘after action’ cut is ...

Abstract

Ever since the understanding of the phenomenon of the Big Bang, scientists have put I all their energies to understand the functioning of all the objects that make our universe. While most of these objects can be seen and observed, Black Holes make for a mystery much difficult to discern. Nevertheless, after years of hard work and energy, scientists and astronomers have managed to establish certain facets of black holes. One of the most important discovery in this respect has been the relationship between Black Holes and the Galaxies. It has now become an established fact that most galaxies, if ...

A wormhole theoretically is known to be a passageway through space-time that can be used to create short routes for extensive journeys that go across the universe. Wormholes are mainly forecasted through the general relativity theory. Wormholes have been forecasted come with the dangers of high radiation, unexpected collapse, and unsafe contact with alien matter. A wormhole when viewed depicts a tunnel that has separated ends in space-time. It can be pictured as a two dimensional tube surface that connects various parts of the surfaces (Nelson, Peter & Rohitash Rao 67). There are no evidences that are observable about wormholes according to ...

Martin Amis's Other People and London Fields

As Brian Finney points out in Narrative and Narrated Homicide in Martin Amis's Other People and London Fields although he is not classified as a crime writer Martin Amis’s stories are filled with crime and focus upon death and murder. . Finney’s critique of Amis’s stories revolves around the continuing themes of women, death, murder and victimization along with their relationship with the enigmatic narrator. In his analysis Finney looks into the author and the zeitgeist of his era as well. He notes that Amis himself describes his work as “"playful literature" (Neustatter 71) and describes himself ...

My topic of presentation was on the expansion of the universe. The center of my discussion was on the accelerating expansion of the universe and the cosmological implications particularly that at some point in the cosmological timescale, the better part of our universe will be unobservable to us. Our planet (or at least our galaxy since the planet would be long over) will be an isolated lonely place and boring with no cosmology to study. Due to the accelerating expansion, galaxies will at some point be moving apart at a speed possibly faster than that of light, this will get ...

Introduction

In recent years the development of experimental techniques of particle physics is widely discussed among professional physicists, and talks revolving around the future of the Large Hadron Collider are the major part of such physicists` discussions. There are a lot of different opinions about the Large Hadron Collider (LHC, onwards), about purpose of its creation and functioning, about repercussions of its performance on science, and either useful or harmful effect on mankind. Herefrom, I will try to explain its importance for the future of particle physics we know nowadays and try to adumbrate its organization, principles of work and narrate ...

Foundation of modern cosmology

Cosmology being the study of the universe has been changing over the years to what we currently view it as. Modern cosmology has been founded on the works of various principals who have studied astrology over time and during different eras. The ancient European medieval and ancient Greeks believed the earth to be the at the universe’s center. They believed that the moon, planets, and sun were orbiting the earth. This idea was believed by many including the Catholic Church who in fact influenced people of their religion to believe so. The Catholic Church banned anybody from ...

Answer 1: For a company to think of outsourcing, there are usually driving forces to this decision. Schindler was driven by various reasons into this decision. It was realized that the traditional manufacturers in India were becoming increasingly complicated and specialized which resulted in increased demand for better facilities and services. Additionally, elevators ...

No one has ever seen a black hole with their own eyes but everyone has heard about black holes. New technology for making telescopes has helped scientists learn more details about black holes but the principles of physics give us our basic understanding. When a massive star dies the type of black hole formed is a stellar black hole. The star caves in on itself when it dies forming a black hole. (Figure 1) When a star with a huge mass dies, part of the start explodes into space – that is a supernova. The area of a black hole is small because the dead star’s ...

Introduction

The subject about time and how time travels is really very fascinating. What is time? What is time travel? Is time travel really possible? We naturally know what time is since we sense it every day but we cannot seem to completely define it. The question of time travel is also very hard to answer. A deeper question is to ask if time is real. Another is to know if time just moves into one direction only. Does time have a beginning or an end? Up to now, we have never truly answered these questions with great satisfaction. By merely ...

Black holes are space zones in the universe that are dark in nature and possess natural forces of attraction that have a very high gravity. This implies that they are able to attract and pull anything including light at a very high speed. This explains the origin of the name, Black hole. Several myths have been generated in many attempts to try and explain what a black hole is and Hollywood is at the forefront of it. Movies from Hollywood portray black holes as time physical entrances to tunnels that if one goes through, he can either move back or fourth in ...
