Essays on Dark Matter

Gravitational, electromagnetic, strong and weak nuclear forces. Gravitational force is an attraction between any two pieces of matter in the universe. Electromagnetic force is present in pieces of matter, which are able to carry electrical charge. Strong force is holding the nuclei of atoms together. Weak force is responsible for radioactive decay. Molecules are built from the atoms and atoms consist of protons, neutrons and electrons. Protons and neutrons are built of smaller particles called quarks. Electromagnetic spectrum is the range of all the light in the universe. Depending on the wavelength and frequency there are radio, micro, infrared, ...

The Lord of Death, in the Indian epic of Mahabharata, asked his son about the most astounding aspect of the present world. The boy responded, “It is that all around us people can be dying and we don’t believe it can happen to us” (Halifax 6). Such typical refusal to accept death’s inevitability is particularly common in the modern Western society. Generally, the mainstream philosophers shunt any interest in paranormal matters like spirit possession, extra-sensory perceptions, spirit mediumship, reincarnation, and out-of-body experiences into the dark corners of their profession (Hales 335). Eminent philosophers like Antony Flew and ...

Introduction

Our galaxy, the star system of our solar system, is called the Milky Way. The Milky Way is a grand cluster of stars visible in the sky as a bright band of fog. In the ancient Greek, the word "galaktikos" means "milk", "milky", so the Milky Way and stellar systems similar to it are called galaxies. In our galaxy, there are more than 200 billion stars of very different luminosity and color ("The Milky Way Galaxy - 200 billion stars", 2016). The Solar neighborhood is the volume of the galaxy, where we can observe and study the stars of ...

Question 1

There are numerous methods used to measure the distance of universal bodies that lie in space. Various geometrical and cosmological characteristics are in the formulation of these measurement methods. The parallax as one of the methods is built on the principle that a difference in angles of objects as viewed by the natural eye is a factor of distance. For instance, taking the eye as the baseline and trying to find out the distance of an object directly a distance away can give different values depending on which eye one uses in viewing the object. This is made possible by the proximity ...

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 ...

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 ...

Introduction:

The proposed field of research in dark energy has the potential of creating vast amounts of clean energy for humankind. However, the proposals are still in the preliminary stages, and there are debates about the suitability of having carrying out the research. The proponents seek to expand the existing body of knowledge with the aim of opening up further applications and hence justifying the initial costs and faith put on them. The proposal, along with its implications, has some advantages and disadvantages. Research into dark matter would serve to satisfy Intellectual curiosity. People are curious about the properties of ...

Dark energy

Dark energy comprises basically of the energy that cannot be observed. Scientists approximate that dark energy comprises about 68% of the universe and this is a major reason why efforts are being made to further its study (Gates, 2009). Scientists also believe that the dark energy can be harnessed and converted into fuels for various locomotives. Its potential for the provision of energy use justifies the study of dark energy. Also, scientists believe that the dark energy contributes to the expansion of the universe. Thus, the study of dark matter and dark energy will provide answers to many scientific queries ...

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 ...

Abstract

The universe contains 100 billion galaxies. Each of these galaxies has billions of stars, great gas and dust clouds with others having scads of moons and planets. The stars release an abundance of energy either from radio waves, X-rays or from other forms of energy that run at a speed of light across the universe. However, all that can be seen is like the tip of the cosmic iceberg and accounts for a small portion of the total energy and mass in the universe. About one-quarter portion of the universe is made up of dark matter that does not release any ...
