  • Earth 1's Escape Velocity
    1,190 words
    Black holes are one of the many things in the universe that scientists still have a muddy understanding about. However, with the incredible advances of technology, we are able to understand more than what we have in the past. Today, the only way to observe these incredible objects are by looking for radiation from the gas surrounding it. What are they? Black holes are no more than a ^3 dead star. ^2 A star that is considered ^3 alive^2 would be our sun. The sun still produces energy by convertin...
  • Concept Of A Black Hole In Space
    847 words
    Black Holes There are many strange and wonderful phenomenons being discovered throughout our Universe. One of the most intriguing is the concept of a black hole in space. Astronomers have discovered a black hole just 1,600 light years away from Earth. The National Radio Astronomy Observatory cataloged this black hole in the constellation Sagitta ri on a star called V 4641. A black hole is one form of a dead star. A star has three choices when it dies, it can: shrink until it is a white dwarf, sh...
  • Actual Proof Of Black Holes
    1,495 words
    title: Black Hole Essay type: Research Paper body: Black Holes are considered a recent discovery in the almost age-old study of our universe. Since the beginning of our time here on earth, Man has always expressed fascination and interest in the sky above us and everything beyond. We look out to the unknown in times of awe, happiness, sadness and confusion. It is only recently that our study and understanding of the universe has begun to increase almost exponentially both in pace and possibiliti...
  • Black Hole And A Neutron Star
    3,874 words
    Black holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole. Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Since our best theory of gravity at the moment is Einstein's general theory of relativity, we have to delve into some results of this theory to understand black...
  • Stars With Initial Masses
    1,224 words
    Human life is a very beautiful experience. The process starts with the fertilization of the egg, to the birth of a baby, through the life a person up until the death of that person. The life cycle of a star is a process that is just as beautiful and fascinating. Before the star begins its life, there are the components that will create the star. The components look as little like the star, then the sperm and the egg look like a baby. However, unlike the creation and life cycle of a human, the ul...
  • Close To The Black Hole's Total Mass
    3,323 words
    Black Holes black hole is the velocity necessary to take one away from one's own gravitational force. For example, the escape velocity of earth is equal to 11 km / 's. anything that wants to escape earth's gravitational force or pull must go at least 11 km / 's, no matter what the thing is. The escape velocity of an object depends on how compact it is; that is, the ratio of its mass to radius. A black hole is an object so compact that, close to it, even the speed of light is not fast enough to e...
  • Event Horizon Of A Black Hole
    4,609 words
    A black hole is an object with a concentration of mass great enough that the force of gravity prevents anything from escaping from it except through quantum tunneling behavior. The gravitational field is so strong that the escape velocity near it exceeds the speed of light. This implies that nothing, not even light, can escape its gravity, hence the word 'black. ' The term 'black hole' is widespread, even though it does not refer to a hole in the usual sense, but rather a region of space from wh...
  • Collapse Into Super Massive Black Holes
    779 words
    black hole, in astronomy, celestial object of such extremely intense gravity that it attracts everything near it and in some instances prevents everything, including light, from escaping. The term was first used in reference to a star in the last phases of gravitational collapse (the final stage in the life history of certain stars; see stellar evolution), by the American physicist John A. Wheeler. Gravitational collapse begins when a star has depleted its steady sources of nuclear energy and ca...
  • Research On Stars And Black Holes
    1,178 words
    By Beatrice A. Lopez Below you will read research on stars and black holes. Black holes are stars whose core has been crushed by gravity. In the text to follow you will see how a star forms, read about its life and how it becomes a black hole. Stars are composed of hydrogen gas and dust. Stars owe their existence to the force of gravity. Stars are created from the thinly spread atoms of dust and gas that swirl throughout space. The atoms clump together into dense clouds that eventually collapse ...
  • Force Of The Black Hole's Gravity
    668 words
    One of the few remaining mysteries of science is the black hole. When a star runs out of fuel to keep it burning, it explodes into a supernova (Intro. to Black Holes 1) After a supernova, some of the matter that was blown off leaves in pockets to different places in space. These pockets contract to from a pulsar, or new born star. The rest of the matter left from the massive explosion of the supernova comes back together forming a neutron star. If the dead star was too massive, the neutron star ...
  • Lower Main Sequence Star
    1,225 words
    Stars over Time star is a self-luminous ball of gas bound by gravity into a single object and powered by nuclear fusion at the core. There are trillions and trillions of stars in our universe and all are different and unique. There are many stages of stars life including main sequence stars, red giants, white dwarfs, neutron stars, and black holes. All stars also have many more variations in each stage of life. The life of a star begins in a nebula, a great collection of gas and dust. Once enoug...
  • Known As A Black Hole
    2,284 words
    The Search for Black Holes: Both As A Concept And An Understanding For ages people have been determined to explicate on everything. Our search for explanation rests only when there is a lack of questions. Our skies hold infinite quandaries, so the quest for answers will, as a result, also be infinite. Since its inception, Astronomy as a science speculated heavily upon discovery, and only came to concrete conclusions later with closer inspection. Aspects of the skies which at one time seemed like...
  • Black Hole's Mass
    752 words
    In our galaxy, there are millions of stars. In our universe, there are millions of galaxies. Humans have known about stars since the beginning of our existence. What we think of these mysterious things have changed over time. Even in periods as short as a lifetime our ideas have changed. I remember when I was young I thought of stars similar to the way astronomers thought many years ago, that the Earth was the center of the universe. As I got older I began to think more like the astronomers of t...
  • Neutron Stars And Black Holes
    2,000 words
    Stars can turn into varieties of things as they collapse, including white dwarfs, neutron stars, and black holes. A black hole is suggested to be the end product of a large star that is collapsing into itself, due to the fact that gravitational acceleration is calculated by the formula; A = Gmb / r^6 Where mb is the mass of the black hole, as the radius, r, of the star decreases, the gravitational field on its surface increases. This causes a chain reaction in which a greater force is put on the...
  • Black Cat Squadrons
    668 words
    Black Cat Squadrons and the Double Sunrise Service Both the Black Cat Squadrons and those involved in "The secret order of the Double Sunrise Service" operated one of the most famous planes in aviation history, the Catalina. Starting in 1943 and ending the operation of the route in 1945, QANTAS crews flew the Double Sunrise Service using the Catalina. The Black Cat Squadrons flew the Catalinas in WWII on various missions throughout the war. The Double Sunrise Service, introduced in June 1943, wa...
  • Existence Of Black Holes
    1,910 words
    Black holes are postulated to be one of the most destructive forces known in the universe, with nothing being able to escape from its gaping maw, not even light. Even, supposedly, all known laws of physics fall apart inside the depths of the black hole. So how does the universe allow these objects to exist? Or rather do they exist or are they just a product of humanity's misunderstanding? Fundamentally black holes are a product of gravity, the weakest of the four known forces in the universe. It...
  • Black Holes Orbit Around Stars
    3,223 words
    By: Nothing Black Holes By: Hazzard Every day we look out upon the night sky, wondering and dreaming of what lies beyond our planet. The universe that we live in is so diverse and unique, and it interests us to learn about all the variance that lies beyond our grasp. Within this marvel of wonders, our universe holds a mystery that is very difficult to understand because of the complications that arise when trying to examine and explore the principles of space. That mystery happens to be that of ...

    593-50-2170 Black Holes Erwin Floresca 593-50-2170 AST 2006-001 Dr. Carol A. Williams Black Holes As the nighttime sky falls upon us and we gaze at the beautiful stars, imagination takes one away from the limits of our solar system to the depths of a high-mass black hole. The universe that we live in contains unique and exciting matter that interests us to learn about all the variances that may only be viewed through a telescope. Within this marvel of wonders, our universe holds a mystery that c...
  • Black Hole's Event Horizon
    1,481 words
    Our solar system consists of ten planets revolving around the Sun. The Sun serves as a magnet that uses its gravitational pull to hold the solar system together. If the Sun were to disappear, what would hold the planets together? The answer might be a black hole. A black hole is a theorized body whose gravity is so strong that even light can't escape from within it (Shipman 64). If light can't escape from a black hole, then it must be invisible – therefore how can we know that the black ho...
