    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...

    Gravity has many benefits to humanity. It holds us to the earth so we do not fall off the earth and die in space. It holds the planets in orbit around the sun, and moons in orbit around their planets. It also holds stars in orbit around the center of the universe. (Gibben, page 14) Sir Isaac Newton thought that God created a perfect universe. He thought our universe was so perfectly designed that if God left the universe could run by itself. This view was extremely different early pagan scienti...

    Kristy Pryzmont May 5 th, 2001 Astronomy HAWK #4 ASTR 220 1. There is evidence that supports the hypothesis that the Milky Way Galaxy has a massive black hole at its core. At the center of our very own galaxy is a mysterious source of energy. Vast amounts of radiation pour from this compact source which may be a Supermassive Black Hole. Astronomers found an intense radio source with strings of other radio sources clustered about it in the direction of the galactic center. The intense source was...

    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...

    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 Holes 3 Star Hole Light

    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...

    Scientists have discovered the closest black hole yet, a mere 1, 600 light years from Earth. At the peak of its X-ray output, V 4641 Sgr was the brightest X-ray emitter in the sky. Astronomers call this type of system an X-ray nova because it suddenly becomes a bright source of X-rays, but this object shows characteristics never seen in an X-ray nova. Smith worked on data from this object with MIT principal research scientist Ronald Re millard and NRAO astronomer Robert Hjellming. Black holes ha...

    The right side of the figure illustrates schematically Doppler shift measurements made on the central region of M 87 that suggest rapid rotation of the matter near the center. The measurement was made by studying how the light from the disk is red shifted and blue shifted by the Doppler effect, using the Faint Object Spectrograph aboard the Hubble Space Telescope. Part of the swirling disk spins in Earth's direction and the other side spins away from Earth, thus causing opposite Doppler shifts. ...

    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 f...

    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 lik...

    String theory is one of the most exciting and profound developments in modern theoretical physics. Unfortunately it is a highly technical subject that can only be well understood using the tools of Quantum Field Theory. It also doesn't hurt to know some mathematics like Group Theory, Differential Geometry, and Algebraic Geometry. Needless to say this is prohibitive for most people who are far too busy doing other things. String theory is to be a theory of quantum gravity, then the average size o...

    The oldest profession in the world is not what would be commonly accepted in society. Before a woman had a chance to sell her body, people looked up at the stars and wondered what they were. They made figures out of the shapes they made. As we advanced through scientific research many other doors opened that allowed us to see what it was the earth is existing in. Our constant need to explain what is happening comes from our want to control. Knowledge is power, and nothing is more unexplained th...

    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 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...

    According to Stephen W. Hawking, Black holes are rips in the fabric of space of the universe. They can be neither be visible to our eyes nor are they detectable by even the most powerful telescope -- the Hubble Telescope -- so far created by man. According to Hawking also, the Black hole are nothing but dead stars. The collapse of the star leads to singularity. The black hole may be described as the final stage in the death of a star before the point of singularity is reached. For Roger Pen...

    "In Black Holes BLACK HOLES "In the beginning, there was light.' That is true in the case of black holes too. Black holes are the result of burned out stars that have collapsed on themselves. When a star begins to run out of fuel, the internal pressure of the fusion reactions, which was before, counteracted by gravity, begins to win over gravity. The star soon can no longer support its own weight and its outer layers escape its gravitational pull. This powerful explosion is called a super nova. ...

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 ...
