Essays on Black Hole

Forewords

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 Continue reading...

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 Continue reading...

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 Continue reading...

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 Continue reading...

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 Continue reading...

Abstract

The study investigates different aspects of the Mirphak star. The Introductory section explains that the star occurs in the Perseus constellation and is the brightest star in the night sky above the Northern horizon. The paper has a section that describes the various names and myths linked to the star. Moreover, the paper traces a Greek’s mythical story that gave the constellation its name. Under the section on properties and position of the star, the study examines the changing coordinates of Mirphak. As a result, it outlines the star’s coordinates in J2000 and J1900. Other features examined Continue reading...

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, Continue reading...

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 Continue reading...

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 Continue reading...

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 Continue reading...

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 Continue reading...

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 thinking Continue reading...

Question 1:
What are possible reasons for the outsourcing strategy of the Indian subsidiary of Schindler? What allowed them to pursue this strategy?

Question 2:

What are the arguments to consider Schindler India a “Strategic Leader” and what are the arguments to consider Schindler India a “Black Hole”?

Answers:

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, Continue reading...

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 Continue reading...

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.

(a) Product-market-focused strategies use actions that focus on the product and the market. So cost reduction might be the best marketing strategy for selling a larger number of the products. Niching requires finding a special target audience with a special need that only this product can fill. Or a product can have Continue reading...

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 Continue reading...

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 Continue reading...
