The Effects Of Dark Matter On A Galaxy 's Matter

Dark matter and dark energy are two entities that have very little known about them, except that they make up about 95 percent of the universe. Even though this is a large part of the universe, it wasn’t even thought about until the 1960’s or the 1970’s. This is because of the fact that it is very hard to detect and almost impossible to see. Although it is impossible to see, we can see the effects of them both in our galaxy.

Her paper had to be approved by the director, Harlow Shapley. Harlow sent her thesis to Henry Norris Russell, who at the time was the dean of American Astronomers, and Harlow’s mentor. Cecilia respected and feared Russell, because of his position and power. After reading her thesis, Russell at first found Cecilia’s findings to be accurate. However, five weeks later he wrote Cecilia saying, “there remains one very much more serious discrepancy... It is clearly impossible that hydrogen should be a million times more abundant than the metals.” (Bartusiak p.34). Despite the quality of her research she believed what Russell had said to her and changed her thesis. After Russell found out that Cecilia was right all along, many astronomers described her work as the most brilliant Ph.D. thesis ever written in astronomy (Bartusiak p.34). Cecilia Payne’s interpretation of Annie Jump Cannon’s classification system made it possible to read the life stories of the

The particles include photinos, neutrinos, gravitinos, axions, and magnetic monopoles, among many others. Of these, researchers have detected only neutrinos -- and whether neutrinos have any mass remains unknown. Experiments are under way to detect other exotic particles. If they exist, and if one has a mass in the correct range, then that particle might pervade the universe and constitute dark matter.

Dark Matter is revealed in many ways and one example of dark matter in action is how it holds our galaxies together. This is known because even though dark matter does not emit or absorb light or electromagnetic radiation, it does exert a gravitational force upon other galaxies, stellar clusters, and many other substances through the universe. One example of how amazing dark matter is is how it exerts a gravitational force upon stellar clusters. Stellar clusters are clusters of individual stars that move at rapid speed that are gravitationally bound. But it has been scientifically proven that the individual stars are moving too fast to be held together by the gravitational attraction of other stars. In this case dark matter provides the extra vigor that is needed.

Dark Matter is a very interesting book that I would recommend you to read. The author of Dark Matter has both assimilation and tolerance in the book. In the book tolerance is used by Jason having to survive in different situations. At one point in the book he goes to a world that is covered in snow. He built tolerance to the cold and was able to carry Amanda to a cabin and survive. But also has assimilation sprinkled in. Jason had to adapt to his doppelgangers and their worlds.

His wife was Minnie Ruth Solomon, most commonly known as Ruth. They were married in 1935. His first daughter, Gloria, was born in 1932. Their second daughter, Marlene, was born in 1939. Their 3rd blessing, Beverly, was born in 1940. These facts show that they had 1 daughter before their marriage, and then waited almost a decade to have 2 more daughters so that their first daughter could grow up.

It is here that he did his first official story, and even worked together with Carl Bernstein in what is now known as the best reporting job ever seen. All the while he decided to take Internal relations classes with George Washington University, and graduaten classes with Shakespeare college.In his time as an investigative journalist, he also wrote more than 15 books, all nonfiction. He has had three wives in his life, the first was Kathleen Middlekauff which he was married to during 1966-1969, they divorced. The same goes for his next wife Frances Kuper thei rmarriage lasted 2 years longer than his previous 1974-1979. His next and final wife is Elsa Walsh which he married in 1989 and is still married to this day. He reported on president Nixon while he was in office along with Carl Bernstein. Today he still works with the Washington Post as an associate editor.

Simulations of galaxy formation based on the Lambda Cold Dark matter (ΛCDM) cosmological model predict that a large galaxy such as the Milky Way should have many (~ 200) dwarf satellite galaxies. However, only about 20 or 30 have been identified. Where are the rest? Warm dark matter, constituting of sterile neutrinos, is lighter and since dwarf galaxies consisting mainly of dark matter are so difficult to find by visible light, there could be enough of them to reconcile the large number of dwarf galaxies that simulations predict to exist with the small number actually observed. We are looking for a weak unidentified emission line at E = (3.55−3.57) ±0.03 keV in a stacked XMM-Newton spectrum of Dwarf galaxies, which are the satellite galaxies of our Milky Way.

Every since I have read your book, Dark Matter, I have looked at reality in a whole different way. Every day when I make a sort of important decision I think what will happen if I take the other option which makes me quaver with fear. During the reading of this book, the plot was dispersing me causing me to try and regain the truth of the story. After finishing the book I was ravenous to hear what will happen next once the entered their new world and I felt like I was hanging of a precipice.

Kerouac’s first wife was Edith Parker. They were married August 22, 1944, but their marriage was annulled in 1945. Kerouac's second wife was Joan Haverty. They were married November 17,1950, but were soon divorced. His third and final marriage was to Stella Sampas. They were married November 18, 1966 and were together till Kerouac's death in October of 1969. During Kerouac's second marriage he had a single daughter named Jan Michele Hackett.

He married his first wife, Gertrude Blugnerman in 1942 and had two children, David, who was born in 1951, and Robyn, whom was born in 1955. (“Internet Accuracy Project” Web.) Asimov only stayed married to Gertrude for 21 years. He divorced her in 1973 and married Janet Jepson, a long time acquaintance that same year (“A&E Networks Television” Web.)

Wernher von Braun was born on March 23, 1912, in Wirsitz Germany. He was born into a very wealthy family. From an early age, von Braun always showed a great interest in science. This interest however increased after his mother got him a telescope as a gift. Later at the age of 11, von Braun was enrolled in the Französisches Gymnasium. While he was there he showed a decent ability to perform in math and sciences. Soon, when he grew a little older his father moved him to another school where he truly excelled and grew in his math and science abilities. His great interest inspired him to read books in his favorite fields. One of his favorite books was Die Rakete zu den Planetenräumen (The Rocket into Planetary Space) by Hermann Oberth. However, he soon realized that he would need to master his skills to be

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 detect them. People question whether they manifest to be the same thing. Astronomers know very little about their constitution so they cannot assume they are related.
