Abstract
The paper defines black holes and explains what they are made up of. The paper explores common misconceptions surrounding black holes, as well as other mysteries. Finally the paper examines theories regarding how black holes eventually end.
From the Paper
"Black holes, one of space's greatest phenomenons, appear to be tremendous concentrations of matter, usually at the center of a galaxy; however, smaller back holes are possible. The matter is in the form of neutrons, protons, and electrons, tightly packed together by their mutual gravitational attraction. The beautifully descriptive name comes from the fact that light cannot exit from a Black hole. They are suspected to form in the death and collapse of a star that began with more than10 times the sun's mass (those with less mass become white dwarfs or neutron stars)."

Abstract
This is an informative paper on what exactly a black hole is and what scientists have theorized about black holes. The paper examines the formation of black holes, past research on black holes and pondering questions still unanswered today.
From the Paper
"Ever since you were old enough to know what the sky, moon and stars were, you have always imagined what is actually up there? One of the most fascinating ideas of all is the mysterious and scary thought of a BLACK HOLE! This is perfectly normal because even today scientists are still pondering over that same question - what is a black hole and does it exist? Theories that at one time seemed reasonable are now laughed at, our skies hold an infinite space which we will never be able to explore, as a result, our questions will be infinite as well."

Abstract
This paper details how Galileo Galilei affected history by discovering the potential of the telescope, pioneering new approaches to science, and challenging the authority of the Catholic Church.
From the Paper
"Galileo Galilei was a mathematician, an astronomer, and a physicist who made several significant contributions to modern scientific thought. During his life, he made many scientific discoveries, often in contradiction with the centuries-old ideas of the Greek philosopher Aristotle. These contradictions led to great conflict with the Catholic Church; however, he emerged as a symbol to others who oppose unyielding authority and champion scientific progress. As James Reston's biography Galileo makes clear, Galileo is a historical figure who affected history by discovering the potential of the telescope, pioneering new approaches to science, and challenging the authority of the Catholic Church."

Abstract
This paper looks at black holes in terms of the most prevalent theories. It first, defines what we have come to understand as a black hole. It then touches upon how black holes are documented and measured. Thirdly, it examines the black hole believed to be at the center of our own Milky Way galaxy. Finally, it explores the prevalent hypothesis that black holes are in fact the genesis of all galaxies.
From the Paper
"Gravity is the cause of black holes. A black hole is the unlimited and irresistible force of ultimate gravity in the universe. To understand how a black hole is created, it is helpful to understand a bit about the basics of gravity. Imagine shooting an arrow into the sky. The harder you shoot the arrow, the farther it will go in attempting to escape the pull of the Earth's gravity. If you were to use a big enough bow with enough force you could help the arrow reach speeds exceeding 7miles per second which is the escape velocity for the Earth. Escape velocity indicates the minimum speed necessary to beat the pull of the planet's gravitational core (Cowen , 390). The strength of the gravitational pull of the core is determined by the density and mass of the core. The denser and more massive that the core is, the greater the gravitational pull. If you were to drop a ball to the center of the earth, the gravitational forces would crush it into an ever shrinking volume requiring even greater amounts of force to help it reach escape velocity. As the greatest theoretical speed for any physical object in the universe is that of light (which travels at 186 thousand miles per second) a mass large and dense enough can actually exert so much force that not even light can achieve escape velocity. The object that can pull even light into it and keep it from escaping is a black hole."

Abstract
This paper explains how if it were not for Albert Einstein the world would be a lot different today as his discoveries and theories lead the way for physicists.
From the Paper
"When ever the phrase great mind or genius is mentioned usually one name comes to mind, and this name is Albert Einstein. This is so, because Einstein may very well have been the greatest mind of the twentieth century. Einstein revolutionized modern scientific thinking and was a master of physics and mathematics. From an early age Einstein showed skills and interests rare among others his age. From the beginning Einstein was destined for something special."

Abstract
The purpose of this paper is to introduce, discuss and analyze the topic of gasoline prices in the United States and offer some insight as to why they are so high. Specifically, it answers the question "Do Americans really have a right to complain?" It also discusses European gas prices, and why they are higher than America's, as well as some alternative fuels that might help ease gas prices in the United States.
From the Paper
"American gas prices may be higher than we have ever encountered before, but they are much lower than gas prices around the world. American drivers are spoiled. They tend to drive large, inefficient vehicles, and then rant about the high price of gasoline. They drive long distances for work and play, using more gasoline per capita than residents of many foreign countries. American drivers also rely heavily on their vehicles, rather than using more efficient and fuel-friendly alternatives, like carpooling or public transportation. We depend too much on foreign oil, a resource that is non-renewable. We need to develop more alternatives to our dependence on gasoline by researching more efficient fuels and automobiles, like the hybrids that have recently been developed by Honda and Toyota, which use a mixture of gasoline and electricity to provide better gas mileage while using less gasoline. Our dependency on oil must stop, or one day, our children will wake up to world without gasoline."

From the Paper
"The purpose of this research is to examine the emerging field of forensic radiology. The plan of the research will be to set forth a working definition of the discipline of forensic pathology and then to discuss the ways in which the discipline is developing, not only on account of methods employed in recent years to exploit the technical capabilities of x-ray technology but also (and more crucially) on account of the enlarged range of medical and legal applications implied by improved technical capabilities.
What must be understood first about forensic radiology is that as of late 1998 it is not a term in wide and common use in the professional literature. To be sure, forensic medicine has long been a part of scientific discourse, associated in both the popular culture and in scientific, professional, and law-..."

From the Paper
"The theory of Eliminative Materialism attempts to prove more about the physical world than dualism, and answers more fully questions of metaphysics concerning the point to human existence. The questions of cognitive sciences are general and particular questions addressing issues such as existence and what sorts of things can exist. Then there are the more particular questions like; Is there a soul?, What is the relationship of the soul and the human body, or the mind to the body? I will go over the major questions pertaining to minds, bodies and existence from the dualist's standpoint and the eliminative materialist's stand point simultaneously."

From the Paper
"Science can be broadly defined as the development of knowledge about the physical world. The history of science is the explanation of the development of this knowledge. Science is often viewed as cumulative and progressive by its nature. Such views, however, can have profound implications because not all scientists or theorists follow the cumulative view. Scientists use both deductive and inductive reasoning to hypothesize the possibility of a useful theory. They also seem to be able to decide or discover more easily which theories are false rather than which theories are true. While the proving or disproving of scientific theory plays a vital part in the growth of science and scientific inquiry, the way that the actual progress or creation and discovery of new ideas and paradigms of thought is at the center of scientific research. Does science move forward in a cumulative and progressive manner or does it move forward in leaps and bounds? "
