A Study Of Dark Matter

Throughout the modern era of astronomy, a single type of celestial object has puzzled astronomers more than any other. Black holes, whose existence was only verified in the early 1990’s, have fascinated scientists ever since Einstein first proposed the theoretical concept in the 1930’s. A black hole is an object so tiny, but also so dense, that it has the power to pull planets, stars, and even light into its core, and ultimately destroy everything in its path. Over the past decade much has been discovered about these enigmas of space and time; however, many of these recent discoveries lead to more unanswered questions. Nevertheless, the basic life cycle of a black hole is now understood in ways thought to be impossible only twenty years

Several hundred thousands years after the Big Bang, the stars began to light up the dark universe. As the universe expanded, it got colder and darker and less like a place that might produce things like heavier chemicals, plants, and animals. This period of the history of the universe was called the Dark Ages. During the Dark Ages, a lot of atoms was flowing through space, which contained 75% hydrogen with one portion and about 25% helium with two protons. Some areas in the universe were just slightly hotter and denser than others, and gravity magnified those differences. As gravity increased, the whole thing was clumping faster. At the center of each of those clouds of atoms, atoms began to bang into each other more violently and heat up particularly

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.

This shows why dark matter is so mysterious, but yet still fascinating, because scientists don’t even have that much information on it, but they know it’s out there. They can tell it’s out there, because it’s affects on it’s surroundings like stars and galaxies. When dark matter is near the light from stars or galaxies, it will begin to bend. This how scientists found out about dark matter, because the light is interacting with the gravitational pull created by dark matter. To gain a better understanding of what dark matter is and how it's different from other types of matter, you have to look at matter that we already know about. So called “normal” matter is matter that we can see like stars, planets, and galaxies. This matter has particles consisting of baryon particles, which is a nucleon that has a weight of the same or increased weight of a proton. Dark matter is none of those things, because when a normal baryonic cloud is exposed to radiation going into the cloud, it absorbs the radiation unlike dark matter clouds. The next matter that we know about is called antimatter, which is when molecules group together in the form of an atom and have positrons, anti-neutrons, and anti-protons particles in it. This forms an extremely unstable matter, which is unlike dark matter that is stable. When you take in account the other types of matter and compare it to dark matter, it shows that dark

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.

Astronomers believe there is enough dark matter in the universe to slow its expansion gradually toward a stop.

“Introduction to Poetry” and “Traveling Through the Dark,” are poems written by Billy Collins and William Stafford. The poem’s, “Introduction to Poetry”, main conflict is a teacher who tries to get his students to read and appreciate a poem, but what all the students only care about is figuring out what it means. The conflict is highlighted through the many uses of metaphors to help us understand how he wants the students to look and decipher a poem and how they only focus on finding the meaning instead of taking their time to listen and see the art of poetry. William Stafford’s poem, “Traveling Through the Dark,” describes a driver’s dilemma of deciding whether to throw a dead pregnant deer into the river, or leave it laying on the road where it can cause an accident. In both poems, the use of literary devices such as metaphors, personification, imagery, and diction are effective in making and building up the conflict and reaching the resolution.

The author of Dark Matter, Blake Crouch, develops the idea of assimilation throughout the book because as Jason Dessen is having to go through all the different multiverses, he is having to adapt to what is happening in that particular world at that particular time. Jason is constantly going into different versions of Chicago trying to return back to his original world, but there are many obstacles that he has to overcome in order to do that. If Jason was not able to adjust to the changes he was experiencing, he could not survive all of the worlds the box was taking him to. Jason is first faced with the tragedies of the box when he is kidnapped by a guy in a geisha mask. This guy forces him to drive to a destination, where he then wakes up next to a metal box, oblivious to what had just happened the previous night.

Crystal Pite professional choreographic journey took off in 1990, at Ballet British Columbia. Over the past twenty-sex years Pite has created over forty works for different companies. Choreographer Pite founded Kidd Pivot in 2002. According to Kidd Pivot organization, “In 2002, she formed Kidd Pivot in Vancouver. Integrating movement, original music, text, and rich visual design, Kidd Pivot’s performance work is assembles with recklessness and rigour, balancing sharp exactitude with irreverence and risk.” (Kidd Pivot Organization). Kidd Pivot has a unique language for all of their choreographed works. Their movement is considered classical with freedom that allows their movement to be free on stage. According to KPO, “The Company’s distinct

In this paper I will explain how astronomers determine the composition, temperature, speed, and rotation rate of distant objects using various methods. I will explain the properties of stars. I will also summarize the complete lifecycle of the Sun and determine where the Sun is currently in its lifecycle.

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.

The properties of regular matter include a composition of neutrons, protons, and electrons; it can be seen and touched. The properties of dark matter are unknown; dark matter cannot be seen, touched, interact with light, or produces radiation. Dark energy is also an unknown entity, but it is considered a form of energy. Dark energy is also known as the energy of nothing or the energy of empty space. Even so the big bang theory is still widely accepted among people as the start of the universe

Dark matter is an element which is non-luminous and cannot be identified directly by electromagnetic light but can be identified. Dark matter is believed to be the fundamental element that makes up the universe, and that could probably be the reason why it is difficult to separate it from other particles.

No school in the country gets more research funding than Johns Hopkins, and as a result no other university would be able to provide me with as many incredible research opportunities. Although I am excited by the opportunity to learn new and fascinating information inside the classrooms of Johns Hopkins, my true passion lies in doing research during college. I have always been intrigued by mystifying concepts such as general relativity, dark matter, and black holes. The learning atmosphere at Johns Hopkins University will encourage me to pursue these mysterious subjects by working on research with the brilliant minds of professors and other

Dark Energy is a mysterious force that drives the expansion of the universe. Astronomers states that the universe is expanding and the expansion is accelerating, so the unknown anti-gravity force at work is termed dark energy. Dark energy has important consequences for
