...Cosmological constant 1 INTRODUCTION In cosmology, the cosmological constant (usually denoted by the Greek capital letter lambda: Λ) is the value of the energy density of the vacuum of space. It was originally introduced by Albert Einstein in 1917 as an addition to his theory of general relativity to "hold back gravity" and achieve a static universe, which was the accepted view at the time. Einstein abandoned the concept after Hubble's 1929 discovery that all galaxies outside the Local Group (the group that contains the Milky Way Galaxy) are moving away from each other, implying an overall expanding universe. From 1929 until the early 1990s, most cosmology researchers assumed the cosmological constant to be zero. The cosmological constant appears in Einstein's field equationin the form of where R and g describe the structure of spacetime, T pertains to matter and energy affecting that structure, and G and c are conversion factors that arise from using traditional units of measurement. When Λ is zero, this reduces to the original field equation of general relativity. When T is zero, the field equation describes empty space (the vacuum). 2 VACUUM ENERGY PROBLEM The...

...I Have A Theory The study of the universe as a whole is Cosmology. Although easy to label, it is not easy to explain. The foundation of modern cosmology can be described as an arrangement of observations, hypotheses, theories using science, technology, mathematics, physics, and analytics (to name a few) to strive for answers about our beginning, present, and future. Through time, many types of people have created stories, myths, and ideas of how we came to be. Until the nineteenth and twentieth century, the evolution of theories was slow. According to Shipper, “New telescopic devices permitting people to see parts of the universe never before imagined, in new ways never before conceived, have advanced man's theoretical capabilities on explaining the origin of the universe, a task that has been a part of intelligent man's life for thousands of years” (para 1, n.d.). As our technology advances, we are able to answer questions. Going back a few centuries to a time of revelation to Nicholas Copernicus, he had a revolutionary idea that paved the way of thinking that the sun was the center of our universe. His proposal published in 1543, a book titled, “On the Revolution of the Heavenly Spheres.” Johannes Kepler, the first astrophysicist, discovered that the planets revolve around the sun in ellipses. This gave birth to the laws of planetary motion. Isaac Newton supported Kepler’s suggestions that planets were kept in orbit by a force, by showing that the same force that keeps our...

Philosophy at this contemporary world has gone through a lot of changes before getting to this stage. It can be seen in the historical perspective and also the topical perspective. The historical or chronological is when we look at the ideas of some philosophers in the past how they influence society with their way of thinking and the motive behind them. In these chronological system is the ancient era, the medieval era, the modern era and presently the contemporary era. In the beginning all systematic search for knowledge was philosophy. This is clearly seen in the modern university where the highest degree granted in all of the science and humanities is the Ph. D. the doctor of philosophy. But the children began to leave home. The first to leave was physics and astronomy. As they begun to develop experimental techniques of their own. This exodus, led by Galileo and Isaac Newton and Johannes...

The observable universe is about 46 billion light years in radius.[7] Scientific observation of the Universe has led to inferences of its earlier stages. These observations suggest that the Universe has been governed by the same physical laws and constants throughout most of its extent and history. The Big Bang theory is the prevailing cosmological model that describes the early development of the Universe, which is calculated to have begun13.798 ± 0.037 billion years ago.[8][9] Observations of supernovae have shown that the Universe is expanding at an accelerating rate.[10] There are many competing theories about the ultimate fate of the universe. Physicists remain unsure about what, if anything, preceded the Big Bang. Many...

...Abstract Eight planets, fifty-eight moons, thousands of asteroids, and billions of meteoroids and comets and one dwarf planet named Pluto orbit the grand star, the Sun. Around and around they go. These planets and other object came from a huge explosion. The Big Bang Theory, which states that the universe began as a dense and hot point that was less than a fraction of an inch and has continued to evolve into what it is known as of today. The origin of the galaxy seems a mystery. But over time, the pieces of the puzzle are coming together. Scientists believe a supernova or star may have formed the universe. When the Earth first formed, it contained gasses which dissolved into the Earth’s molten planet. When this formation happened from the smaller bodies, these were called planetesimals. But not all planets are the same. The Jovian planets are shrouded by thick atmospheres that are rich in hydrogen and helium. These planets were formed away from the sun. A shooting star is what individuals think of when they see a vapor stream of dust and gas shooting across the sky. The sun helps make this spectacle possible and could be a reason why early astronomers were so curious about the skies. When an individual looks up at the night sky, he or she can get lost in the vast beauty. Who wouldn’t get mesmerized?

...1. b There are two clues to solve this question. The first is the mandatory pair (A-B). Statement B has to come immediately after statement A as B is the response of the Labour party to the “row about the legitimacy….” mentioned in A. This leaves us with options (b) and (d). Here the difference is in the order of statements D & E. (D-E) would be the correct order as statement D introduces the event while statement E begins the description of the events that followed. Statement E also matches the tone of statement C. The paragraph has a mandatory pair (D-B) as B carries further the idea of opening of the cages, which gets introduced in D. (C-A) is another mandatory pair. Statement C compares India’s performance on social indicators with that of Asian economies. Statement A further compares India’s performance with that of poor African countries. Only options (c) and (d) have both mandatory pairs. Option (d) gets negated as the paragraph must start with C, which introduces the para. Option (c) aligns all the statements of the paragraph thereby making it coherent. Statement C clearly emerges as an introductory sentence “an episode regarding the….”. (A-E) is a mandatory pair as in statement E Akbar gives reasons to refute Hakim Ali’s argument. The only possible answer choice is (b). 6. c Option (a) clearly refers to the opening of the story which is gruesome yet comical. Option (b) is correct as the author creats humour inspite of Brr not knowing language for very long. Refer...

...The Collapse of Sensemaking in Organizations: The Mann Gulch Disaster Karl E. Weick . Reprinted from The Collapse of Sensemaking in Organizations: The Mann Gulch Disaster by Karl E. Weick published in Administrative Science Quarterly Volume 38 (1993): 628652 by permission of Administrative Science Quarterly. © 1993 by Cornell University 00018392/93/3804-0628. This is a revised version of the Katz- Newcomb lecture presented at the University of Michigan, April 23-24, 1993. The 1993 lecture celebrated the life of Rensis Likert, the founding director of the Institute for Social Relations. All three people honored at the lecture-Dan Katz, Ted Newcomb, and Ren Likert-were born in 1903, which meant this lecture also celebrated their 90th birthdays. I am grateful to Lance Sandelands, Debra Meyerson, Robert Sutton, Doug Cowherd, and Karen Weick for their help in revising early drafts of this material. I also want to thank John Van Maanen, J. Richard Hackman, Linda Pike, and the anonymous ASQ reviewers for their he lp with later drafts. The death of 13 men in the Mann Gulch fire disaster, made famous in Norman Maclean's Young Men and Fire, is analyzed as the interactive disintegration of role structure and sensemaking in a minimal organization. Four potential sources of resilience that make groups less vulnerable to disruptions of sensemaking are proposed to forestall disintegration, including improvisation, virtual role systems, the attitude of wisdom, and norms of respectful interaction...

...Mysteries of the Multiverse Name: Assif Khan Student no: Subject: PCS-181 The term multiverse has many nicknames including but not limited to quantum universes, alternate universes, alternate realities etc. But, what is the multiverse? If one was to look up the meaning of the word, the definition that is provided in the Oxford Dictionary states “a hypothetical space or realm consisting of a number of universes, of which our own universe is only one”1. The use of the term multiverse or its other moniker parallel universe, has been used in cosmology, physics, and philosophy to perhaps more prominently in science-fiction literature and movies for decades. Ever since Edwin Hubble discovered that the universe is expanding in the 1920s, there have been questions regarding the possibility of there being more than one universe. However, there has been no evidence to support the existence of multiverse. Interestingly, despite us humans being inherently logical beings, we still entertain the notion of multiverse which someone has yet to discover or observe. Why should the notion of having more than one universe than our own be any more valid than other scientific idiosyncrasies? As it turns out, the existence of parallel universes was not readily acceptable to physicists either. However, Eternal Inflations theory, String theory; which predicts the possibility of the existence of more than trillions of universes within multiverse as well as there being more than three dimensions...

...Have you ever wondered why there's so much empty space in the universe? it turns out that more than 70% of or known universe is made up of Dark Matter. What is Dark Matter? Why does it take up so much space? How can we use it for the betterment of our universe? There are so many questions that arise when something we know little about makes up so much of where we live. What I Already Know About My Topic: I chose to write about Dark Matter in the universe because it is a very rarely known thing in human understanding. When someone thinks space, they think planets, galaxies, and “Star Wars.” When I took my first high school science class, the very last section we had was about Dark Matter, and I had visibly freaked out to the point that my teacher asked me if I was okay. When it comes to “galactic” science, I tend to know quite a bit more about the subject than those that taught it to me because I was always a “Discovery Channel” child. Dark Matter is an interesting thing that you seldom hear or see anything pertaining to. This is why I have chosen to “teach” you about this potentially catastrophic element. Have you ever just taken a moment to look up at the stars and thought, “Wow, there’s quite a lot of black up there! I wonder what it is?” Well, ladies and gentlemen, that “space” that surrounds us is actually not space at all! It is filled with boundless amounts of an element that doesn’t exist within the Earth’s atmosphere! Surprisingly...

...Q) Discuss the revolution in Cosmology from Copernicus to Newton. In your essay, address the steps resulting in the breakdown of long held beliefs from Aristotle’s days, and Ptolemaic theories. * Prior to Aristotle. There were several other models of the universe, with the Phytogrean universe the most popular. In this model there existed a central fire in the middle of the universe, from which all light descended. * In Aristotle’s model of the universe the world outside the Earth existed, finitely, with nothing ever moving. With the universe in the same position as it ever was. This model of the universe was widely accepted and considered to be a scientific fact for many generations to come. According to Aristotle the universe was filled with a substance called aether to compensate for its dynamic nature. * One of the most important reason for the wide acceptance of Aristotle’s model of the universe was that it correlated with religious views of the time. * Aristotle’s model was further adopted by Ptolemy, to create Ptolemaic view of the universe. This led to the birth of the Aristotle-Ptolemy universe. In this model the Earth was the centre of the universe with the universe revolving around it. * The view persisted for more than and allowed the astronomers to predict the movement of the galaxy and the stars around the Earth. Star charts were developed first in this era. By the sixteenth century this view was intertwined into all of the world’s cutltures. * In the sixteenth...
