Dark Energy Vs Dark Matter

Cosmology Cumulative Paper In order to understand our place in the universe, we must understand the universe itself. Scientists, researchers, astronomers, cosmologists, physicists, amateur astronomers and a slew of other groups of individuals largely interested in the cosmos, help with discovering new and fascinating theories or proof of different phenomenon within the universe. Three scientific articles help readers to realize scientists are constantly deep in work to unravel the hidden truths. “Dark Matter in the Discovery Age”, “Why the Universe Had no Beginning”, and “What String Theory tells Us About the Universe” include theories vastly different from one another, but lead to the same conclusion; the universe’s creation.

“Dark matter is a hypothesized form of matter particle that does not reflect or emit electromagnetic radiation. The existence of dark matter is inferred from gravitational effects on visible matter, such as stars and galaxies”(Andrew Zimmerman Jones). Dark matter is crucial to the study of the universe and the existence of the human race. Since either dark matter or dark energy have neither been actually observed and all theories, we will be evaluating them from scientific standpoint. Since most of the light in the universe is not seen or can be seen because of the existence of dark matter, no one can really tell what exactly it is. This is why “dark matter” is the generic term used to describe the part of the universe in which light is neither absorbed nor reflected. Through the evaluated articles, we can deduce that the theory was first proposed by Astronomer Jon Oort in 1932 and further examined in 1933 by Fritz Zwicky. While studying, he made note of a large portion of “missing mass” within the galaxy. Jan Oort was studying the matter in the galaxy and noticed that there has to be more mass then that could be seen but figured that he made an error. Astrophysicist Fritz Zwicky made a similar observation when using mathematical equations to calculate the mass of the universe and noticed that there was evidence of invisible matter. Both men basically theorized that there is something in the universe thats invisible and abundant that provided enough gravity to hold

Dark Matter Some scientists now believe it is not the matter we see, but the matter that hides in the dark that holds the true secrets of the universe. There is a mysterious dark matter that binds stars and galaxies together, and this matter might be made up of WIMPS, MACHOS, and axions. Physicists continue searching for dark matter, and particles that make up dark matter. Dark matter has strange characteristics and behaves quite differently from ordinary matter. Understanding dark matter is essential to understanding how the universe behaves.

There is perhaps no current problem of greater importance to astrophysics and cosmology than that of "dark matter". The controversy, as the name implies, is centered on the notion 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/supercluster observations.

A) TRUE 25. The oldest stars in the Milky Way are found in the disk. B) FALSE 26. Astronomers believe there is enough dark matter in the universe to slow its expansion gradually toward a stop.

The universe is the entirety of space, time, matter and energy. Today scientists theorize that the universe is dominated by invisible matter rather than visible matter. What is this mysterious invisible matter that makes up the majority of our universe? Scientists call it dark matter. But other than the fact that exists, scientist know very little about it, and are more certain about what it is not than what it is (Dark Energy, Dark Matter, n.d.).

Dark matter is a very mysterious concept and scientist are not sure what it is . Dark matter is a substance that we do not know exactly what it is. Dark matter is something that is matter but is invisible to the best machines.Some of them are x-ray telescopes and dark matter is too cold for the machines to see. Can you believe that you can't see dark matter with our technology?

The difference and similarity that were found between a negative muon and electron was that: Difference The electron was found to have less mass (or rest energy) then the negative muon. Similarities They are both found to be fundamental particles, meaning that they are either a lepton or they are both negative.

Basically, the gravities of the clusters of galaxies that exist outside the voids are drawing in more galaxies, which increases the gravity of the cluster, creating a never ending cycle. As Hadhazy said, “…these overdense regions of matter gelled into galaxy clusters leaving the underdense voids to grow emptier.” (Hadhazy 49). For example, Hadhazy explains this grouping with soap suds, describing how the tiny bubbles in a kitchen sink often join together to form larger bubbles, after which the larger bubbles join to create even bigger bubbles. Galaxies form the same way, smaller galaxies joining together to form larger galaxies over and over, eventually creating the galaxy clusters we find in the universe today (Hadhazy 50). This gives us an insight into what the universe might look like to us in the future. Hadhazy posits that if humankind’s descendants somehow were able to survive billions of years into the future, the universe outside the Earth’s atmosphere would look remarkably different: no stars, no distant galaxies, just an all-encompassing abyss (Hadhazy 53). However, this is not the only window into time these voids may have

Of course, as intriguing as a black hole’s effects within in and around galaxies could be, we must also keep in mind that some theorists believe black holes are responsible for producing, Dark Matter. As stated by the “The Gale Encyclopedia of Science”, in their article, “Dark matter”, Dark matter is, “material that does not emit or reflect light and that is therefore invisible” (The Gale Encyclopedia of Science). Scientists believe dark matter and black holes are in relation, because recent studies done by Russian astrophysicists Vyacheslav Dokuchaev and Yury Eroshenko, institute that, “dark matter could be made of microscopic — or quantum — black hole atoms (Dokuchaev, Eroshenko). In a sense, making it dark, however, as reported by the “World of Scientific Discovery”, in their article, “Dark matter”, “dark matter does not behave like ordinary matter, such as dust or gas, which leaves traces by emitting, deflecting, or absorbing electromagnetic radiation” (World of Scientific

W hat is the universe? How was it created? This is one big question that has been pondering scientists and philosophers since the beginning of time. In the new day, the argument amongst researchers and astronomers is that the universe was created by the Big Bang. A large eruption which, not

Dark Matter and Dark Energy Dark Matter and Dark Energy are important. They can help us know how the universe began. These two are the mysteries of the universe; they compose about 90% of the universe. They are mysteries because we believe that they exist but we can’t see them or

The universe is a magnificent place. There are thought to be more than 100 billion galaxies, each, with 100 billion stars (Hawking 48). There are vast clouds of gas, light years across, each taking on its own dazzling shape and color. In our solar system alone, there are planets asteroids,

Carolyn Godfrey English 101 Ms. Lazzo 10/26/2010 Theories of how Life on Earth began We certainly know that our universe exists, however, this knowledge alone has not satisfied mankind’s quest for further understanding. Our curiosity has led us to question our place in this universe and furthermore, the place of the universe itself. Throughout time we have asked ourselves questions such as: How did our universe began? How old is our universe? How did matter come to exist? Obviously, the search for clues has not ceased. Yet, after all this energy has been expanded, much of what we know is still only speculation. We have however, come a long way from the mystical beginnings of the study of cosmology and the origins of the universe. The
