So what the heck does a quasar have to do with a black hole? What is a quasar? Highly lit objects in space were recently discovered using radio telescopes. Cosmologists called them quasars, for lack of a better term. They appeared to be quite small, but illuminated the universe around them. To make a long story short, they turned out to be feeding, black holes. Feeding black holes? Black holes eat? What do they eat? Italian food? No, they eat matter and gases that get close enough to be lured in and swallowed up. As the black hole voraciously feeds, it becomes overloaded with gas and blows it out (just like people) causing an immense light. Black holes are at the top of the food chain in the universe. Quasars are simply black holes that are having a snack.
Using laser beam technology at the Keck Optical Telescope Center in Hawaii, the black hole in the center of the Milky Way Galaxy was recently detected. Cosmologists lucked out when a massive, gas cloud approached the center of the galaxy. As it began its journey into the event horizon, or edge, of the black hole, it became elongated and traveled faster and faster. As the black hole began to ingest the gasses, it began to shine billions of times brighter than the Vegas Strip at midnight. The friction created by the swirling molecules caused the bright light. Feeding black holes do not gobble up their food in one mouthful. The gas cloud at the center of the Milky Way is not expected to be completely ingested until mid-2014.
Cosmologists are assured at the center of every galaxy is a preying, black hole, but not all black holes are the center of a galaxy. Some black holes, large and small, wander aimlessly throughout open space. Most physicists agree that any mass nearing the e...

...pite the alleged differences that abound between believers and scientists, both sides can agree that the universe is an exquisite, mysterious, and super-elegant place.
Scriptural authors did not understand matter, energy, space, time, atoms, particles, strings, gravity, strong and weak nuclear forces, electromagnetism, parallel universes, mathematical equations, and primordial soup (the only soup they were familiar with was made with lentils). Prophets of old knew that diversified life existed; they saw the stars in the Heavens, the oceans, the earth, and the sky. They attempted to explain how the world and living things came to be, something scientifically unexplainable at the time. They believed there had to be a source, one ultimate force responsible for everything in the universe. They visualized a beautiful creation and recorded it in such a poetic way.

Essay The Impact of the Andromeda-Milky Way Collision

- The discovery of the vast universe, that exists outside our galaxy, began with Edwin Hubble’s discovery of a Cepheid Variable star in Andromeda, which he used to measure the distance to our neighbouring galaxy (Bennett et al. 109). This was instrumental in establishing Hubble’s law or the theory that the universe is expanding and galaxies are moving away from the Milky Way (Bennett et al. 109). However, Andromeda poses a contradiction; while other galaxies are moving away from the Milky Way, Andromeda is actually moving towards it and is set on a collision course with our galaxy....   [tags: black holes, galactic interaction, universe]

The Existence of Black Holes Essays

- The Existence of Black Holes I have always had an interest in science, especially in the sciences regarding outer space. When I was younger I was always fascinated with rockets, and especially in stars. I have often regretted not pursuing this interest at its infancy. I do remember going to the Planetarium, and studying about a topic that I had seen talked about on television. The topic was black holes, and back then all that they knew was that they were black. The idea of a space in the universe that is completely void of light was difficult to imagine....   [tags: Concept Essays]

Essay on The Universe

- The Universe Luminosity is the amount of light that is radiated from a star. White light is the composition of all colors. In elements, the energy discharge can be displayed as light. Just by looking at the colors that are discharged, one may precisely identify the element. In understanding the universe, the Doppler effect is one of the most important tools. The Doppler effect is a shift in frequency due to a moving source. Skipping a rock on water would be an example of this effect. The circles would be off center because the rock is a moving source....   [tags: Papers]

How the Universe was Created Essay

- Scientists have had many arguments on how the Earth is really shaped. Some say that the Earth was round rather than a flat plate. It came to mind on how the Earth was really shaped when there were eclipses on the moon. If the Earth were a flat disk, the shape of the moon would be stretched and arched. Also, Aristotle, a Greek philosopher, thought that the Earth was stationary. He believed that the sun, the stars, and the moon orbited around the Earth. A Greek philosopher named Ptolemy made a model predicting the alignment of the galaxy, and the Christian church adopted his model....   [tags: science]

Essay The Origins of Super-massive Black Holes

- Super massive black holes are enormous black holes which have a mass equivalent to large numbers of solar masses. A black hole is called a super massive black hole when a normal "galactic nuclei black hole" has a mass range between 0.1 million to 10 million solar masses. (Cardiff University 2014). It is believed that one solar mass is equal the mass of the sun, so that would make a super-massive black hole very large compared to the sun. Super-massive black holes having a large mass would make its gravity incredibly limitless, this would mean that even a star which is many light years away would be impelled by the super-massive black hole....   [tags: Black Holes Essays]

Essay about Black Holes, Powerhouses of the Universe

- Introduction Black holes are incredible processes that happen in space that are capable of crushing anything unlucky enough cross paths with them. Black holes have caught the attention of millions of people around the world because of their incredible strength and the fact that so much is unknown about them. The theories of possible outcomes resulting in traveling into a black hole has been used in many science fiction stories, but what we think is science fiction could actually exist. With black holes being out of our reach, and even difficult for our greatest minds to understand, what happens within them may just stay science fiction....   [tags: Birth, Structure, Power, Wormholes]

The big bang theory is just one of the theories of how the universe was created,most and is the most popular out all of them . One of the other believes is that god created everything and nothing else could have made it . The idea of the big bang theory was made in the early 1920 by a guy named Georges Lemaitre .

Edwin Hubble also supported his idea because it went along with his observations that the galaxies were moving away due to something....   [tags: universe, george lemaitre, model]

Cosmology Cumalative Paper

- ... It is difficult to observe WIMP’s on the Earth’s surface due to cosmic rays, which are particles outside of Earth. Physicists choose the underground for its shielded affect, and because WIMPs have a special quality; they cannot be absorbed or reflected unlike other matters. When the WIMP hits the detector underground, the particle’s energy transfers to this detector and physicists will notice a small “thermal or light signal”(Hooper, 28). XENON-100 is an example of this experiment. This piece of equipment contains cold liquid xenon, a heavy gas present in the Earth’s atmosphere....   [tags: universe, cosmos, phenpmenpn, creation]

Physics of Black Holes Essay

- Black holes - the strange scientific phenomenon that has astounded physicists and astronomers alike for decades. Popular subjects in science fiction novels, black holes are one of the greatest enigmas of the scientific world. Even today, the concept of a super-dense ball of matter that not even light can escape from is somewhat farfetched, and many scientists disagree with each other about nearly every aspect of a black hole. This project will attempt to shed some light on these mysterious formations, and will inform you the reader of the most popular and widely accepted theories surrounding them....   [tags: physics space black holes]
