“Why is the night sky dark?” For thousands of years this question has been asked. Astronomers are continually growing closer to the answer but still no one has yet found an answer that is efficient enough. While scientists steadily collect data, they are hoping to find some clue as to realize that the answer may be because of something that is too mind blowing for us to comprehend. There is perhaps no current problem of greater importance to astrophysics and cosmology than that of "dark matter". The controversy is centered on the conception that there may exist an enormous amount of matter in the universe that cannot be detected from the light that it emits. The evidence of dark matter is from the motions of astronomical objects, specifically stellar, galactic, and galaxy cluster or supercluster observations.
Observations from the universe around us are looked upon as scientifically as possible. However it is through the electromagnetic spectrum, which is everything from radio waves to gamma waves, which we learn about the objects in our world and beyond. Nonetheless we can also learn about our universe through indirect resources, such as the effect of gravity on light as well as larger objects like our galaxy. In reality, this indirect method of observation has led us to the discovery of extra-solar planets. As it turns out this indirect method has brought into picture the findings of a new and strange substance that may well constitute seventy percent of our universe. In the past we once believed space was nothing more than random stars and planets along with gas floating eternally in a sea of emptiness. Now we have proof that our galaxy and countless others are floating in an ocean of dark matter. At this time though, the char...

Dark matter plays another very essential role in the universe. Back when the Big Bang was only minute’s old, dark matter mysteriously was able to forge early cosmos of hydrogen into helium. So history shows that dark matter effects are real. The focus is now on trying to develop a better understanding of what dark matter is and how it functions. Although it carries massive force, it can not make nuclei and therefore, it has not been documented to interact via nuclear force. Dark matter has been around for 380,000 years in the universe and we will continue to need dark matter in our own galaxy and in galaxies clusters to explain the motions of objects they contain. With that being said, astronomers will continue to work tirelessly to gather up as much knowledge and observations as humanly possible to exploit the true facts about dark matter.

Essay on Dark Matter - Dark Matter For centuries, physicists and philosophers alike have wondered what makes up our universe. Aristotle thought that all matter came in one of four forms: Earth, Air, Fire, and Water. Since then we have come a long way, with the discovery of the atoms and the subatomic particles they are made of. We can even guess at what makes up protons and neutrons. We have since then discovered and predicted the existence of particles other than the atom, such as the photon, neutrino, axion, and many others....   [tags: physics science space] 2643 words

Dark Matter and Dark Energy Essay - ... The galaxies we observe today would fly apart because they wouldn't have enough matter to create a strong enough gravity to hold themselves together. Dark matter is also responsible for amplifying small fluctuations in the Cosmic Microwave Background back in the early universe to create the large scale structure we observe in the universe today. Astronomers are still in the hunt of the Dark energy and dark matter but they haven’t found none. They are undetectable which makes it very hard for them to see or convince others to believe in their existence....   [tags: armillary, mysteries, exist, universe, force] 1719 words

Essay about The Expanding and Accelerating Universe - In 1998 The Accelerating expansion of the Universe was discovered by two competing groups of scientists called the Supernova Cosmology Project and the High-Z Supernova Search Team that were led by Saul Perlmutter, Adam Reiss, and Brian Schmidt. And In 2011 they were awarded noble prizes in physics for their discovery of the accelerating expansion of the Universe. They did so by applying new technologies like computers and digital cameras to study and measure the spectrum and brightness of the light from other galaxies....   [tags: Dark Matter, Expansion, Spectrum]

In the Shadows: Examining Light and Dark Imagery in "Romeo and Juliet" Essay - John Steinbeck once said “It's so much darker when a light goes out than it would have been if it had never shone”. In order to appreciate something for all that it truly is, one must learn to compare it to its opposite. These opposites both complement each other and bring out the worst in one another. Moreover, they also produce energy through the tension they create. This is true of opposition everywhere, literature included. Authors often make use of it, thus making their works more interesting and relatable....   [tags: energy, light, dark, setting, love] 1487 words

The Universe and It's Phenomenons Essay - The universe is an unknown place. Most of it has not been explored. Some things are known, however. Scientists know a lot about things like the Big Bang and our Asteroid Belt. Some of the universe's natural phenomenons are yet to be discovered. This article will explain some of them and why they happen. In the year 1929, Edwin Hubble made a revolutionary discovery. He learned that the universe is expanding. He saw that the galaxies were each moving away from us. Edwin knew that for one instance of time, almost 14 billion years ago, all of the mass of the universe was contained in a single spot....   [tags: big, bang, asteroid belt, expanding universe]

Dark Matter and Dark Energy Essay - ... The effects of dark energy were first seen in the 1990’s when scientists were watching IA supernovae. Scientists had already figured out how to calculate the distance of Ia supernovae, and they thought they knew the distance of the supernovae, but they were off by a lot, which means that there is an energy source that is pushing the universe apart. The Theories of Dark Matter and Dark Energy What are there two phenomena though. There is very little that is known, but we do know alot of what they are not....   [tags: theories, universe, gravity, supernovae] 779 words

Essay on The Big Bang Theory of the Origin of the Universe - INTRODUCTION Since the beginning of time, people have wondered about why we are here, how we got here, and where we came from. Although many of these questions have not been answered, the question of where the universe we see today came from has been answered, or at least answered as well as possible with the technology available. Currently the leading theory for the origin of the universe is the Big Bang theory. Although some scientists still dispute this model for the development of the universe, the vast majority of scientists accept it as truth....   [tags: Origin of the Universe]

Essay about Human Existence and Human Suffering - All throughout our history, we humans have constantly evolved and developed to an extent where we can give an account to the world we live in. From Epicurus to Thomas Aquinas, from Aristotle -who taught one of the greatest kings namely Alexander the Great- to Sartre and Camus were all for the search of why we are on this planet. What drives us to live or perhaps to die, even if it is by one’s own hand. When arguing about the meaning of life, one has to take into account that every doctrine, thesis, antithesis, thought and emotion can only be explained and defined through the human perspective....   [tags: Human Existence]

Essay about A Man Said to the Universe - A Man Said to the Universe Stephen Crane wrote many remarkable poems, short stories, and novels throughout his short life (He lived only to the age of 29). In one poem in particular, "A Man Said to the Universe," Crane uses cosmic irony to depict an existentialist way of life. "Cosmic irony occurs when a writer uses God, destiny or fate to dash the hopes and expectations of a character or mankind in general"(2133). Crane’s use of this type of irony is seen through the relationship that the universe displays with mankind....   [tags: Man Said Universe] 336 words
