Dark Matter Essay

exactly dark matter is, they can confirm that it is affecting the shape and structure of galaxies in the universe. Observations of luminous matter in the universe show that it clumps together to form galaxies. However, there isn’t enough luminous matter to gravitationally keep itself together. This is how scientists confirm dark matter exists, by seeing how it keeps regular matter together through gravity (Basulto). Currently, physicists know that galaxies form around dark matter halos. When dark matter

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 matter than does not emit any light or any

from Dark Matter Observations." (2013): n. pag. Cornell University Library. Web. 10 Nov. 2015. Tanushree Basak’s journal is peer reviewed, and she works in a physics research laboratory so her article is credible. This source is used in the paper to help introduce the concept of dark matter. It helps describe what percentage of the universe is made up of dark matter. Additionally, it provided information on how dark matter was formed at the beginning of the universe. Basulto, Dominic. "Dark Matter:

Dark Matter was first proposed by Fritz Zwicky in the 1930’s when he observed the motions of galaxies and he noticed that the amount of visible objects could not account for the observations he made. There had to be some “invisible” mass holding these galaxies together. It is known that 25% of our universe is made up dark matter versus 4% of the visible matter we know and interact with every day. The leading candidates for dark matter are MACHOs and WIMPS. Gravitational lensing is one of the ways

Dark Matter is a form of matter that is believed to account for approximately 90% of the matter in the universe. The majority of dark matter is non-baryonic in nature, being made up of some undiscovered particles. Dark matter has not been directly observed, but its presence is seen in a variety of astrological theories, including gravitational effects that cannot be explained unless more matter is present than can be seen. Most astrologists believe dark matter to be all over the universe and to have

more about dark matter in unknown rather than known. we know how much dark matter there is because of its effect on the expanse of the universe, but besides that, it 's a complete mystery. but it is important we figure it out, because dark energy takes up about 68% of the universe. dark matter takes up approximately 27%,everything else, like the earth, and all of our observed universe and all normal matter, takes up less than 5% of the universe. yet even though it takes up so little of the universe

Even though dark matter is in existence we don’t have the instruments available to detect it yet. A theory suggests that dark matter is what actually makes up a large portion of our universe. Even though we can’t detect it, we know dark matter exists because it can interact gravitationally with visible matter and radiation. A professor from New York stated that dark matter plays a large role in causing geological catastrophes as well as mass extinction. ` An example of when dark matter played a role

audience what dark matter and dark matter is by explaining what they are and do. Thesis: Dark Energy and Dark Matter have been puzzling phenomena in astronomy ever since their discovery in the 1900s. To better understand dark matter/energy, I will give information about when and who discovered them, what we learned from them since their discovery and what scientists are doing to further study them.

“The universe is made mostly of dark matter and dark energy, and we don’t what either of them is,” a quote by Nobel Prize winning astrophysicist Saul Perlmutter. Dark Matter is currently a conundrum for modern physicist. Only 4% of our universe is known to us, which means 96% is still a mystery. This paper will focus on the dark matter that currently makes up 27% of our current universe. To understand dark matter, we must understand how we came to identify dark matter. From there we can understand
