  • 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...
  • Event Horizon Of A Black Hole
    1,463 words
    If theories of their existence are true, black holes are the most powerful force in the known physical universe. Many people are familiar with the term black hole, but few people actually know anything about them. A black hole forms asa result of a massive star running out of fuel to burn (Chaisson, 193). Once the star is no longer exerting outward force by burning off gases, it begins to collapse under it's own intense, inward gravity (Chaisson, 193). It is like slowly letting the air out of a ...

    What exactly IS a black hole With all the excitement surrounding the new Star Wars movie, it is a big day for lovers of science fiction. But how much does the average person really understand about beaming up; phases and photons; wormholes and warp drive How powerful are these fantasies compared to the real thing If theories of their existence are true, black holes are the most powerful force in the known physical universe; however, do they even exist Most scientists believe so, but by their ver...
  • 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...
  • Energy From The Black Hole
    1,132 words
    The theory that black holes have existed is not new at all. The thought of them first started in 1783 when Rev. John Michell applied Newton's theory of gravity to predict the possibility of so-called "dark stars". Albert Einstein's theory of relativity predicted in 1915 "Schwarzschild singularities". In 1967, these were renamed "black holes". A black hole is collapsed object (usually a star) that has become invisible and has such a powerful gravitational force that nothing, even light, can escap...

    ASTRONOMY"A New Black Hole" "Scientific American " September 13, 2000 Evidence that the heavens house a previously unknown type of black hole was reported by scientists yesterday. Data from NASA's Chandra X-Ray Observatory revealed a hole was some 600 light-years from the center of the starburst galaxy M 82. The brightness of the x-ray source indicates that this moon-size hole has the mass of at least 500 suns, making it intermediate between stellar black holes and the super massive black holes ...
  • 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 ...
  • 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...

    599 words
    One of the many interesting and fascinating items of modern physics is black holes. Complex and unusual, these objects have captivated many people. They have even been featured in many science fiction stories. In actuality, these objects, may be quite commonplace, and are not, in fact, a discovery of recent years. This essay will serve to describe how black holes were discovered, and briefly describe what they are. Black holes are not holes in space, nor are they uniform in size, they are unusua...
  • Black Hole The Photon Sphere
    5,168 words
    Black Holes. Fact or Fiction? Over the years black holes have been portrayed as portholes to other dimensions or times, gates across the galaxy, objects of death and destruction, or all of the above. Black holes are real, that is one of the few things that we do know about them for sure; we also believe that we have a firm grasp on how they are created and what they do, but their purpose still remains a mystery. What is a Black Hole? To answer that question right off: a black hole is an area in ...

    Black Black Holes Black Holes Black holes are one of the more bizarre and intriguing predictions of Einstein's theory of gravity. Surprisingly, there is now a great deal of observational evidence that black holes do exist, both in binary star systems and at the center of most galaxies, including our own. Although we are gaining more knowledge of black holes, they still remain one of the strangest things anyone has ever heard of, and we may never know what exactly one of these things are and can ...

    720 words
    Mike Black Holes BLACK HOLES Mike Carey Scientists have been trying to determine if black holes (earlier known as 'frozen stars) truly do exist for several decades now. Thanks to the great Albert Einstein and his theory of relativity, researchers have been able to predict the cosmic phenomenon of black holes. A black hole is basically an area of space that has an unbelievably high area of concentrated mass for the space it occupies, making it impossible for an object to escape its gravitational ...

  • 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...
