Our Laws Essays - Physics, Astronomy, Black Holes, Science

Our Laws 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 that the universe. Time is interlocked and must be understood if we want to accomplish a deep knowledge of the cosmos. Commonly it was thought that there was no such knowledge. The author Stephen Hawking had shown many otherwise. His books give a deep history and knowledge of how the universe exists. He also explains many others aspects of the cosmos and puts his works in an understandable writing style. He puts the largest accent on his studies of black holes. These are fascinating happening and the way to understanding the universe and several others can be found through the study of black holes. There are several features of black holes that makes them incredibly fascinating. The first one would be the common misconception of how noting can escape a black hole. This is true in most points. If nothing can escape them, how does one detect a black hole? Stephen Hawking discovered a fascinating aspect using anti-particle properties. He found that when matter is pulled into a black hole by gravity matter is constantly being pulled apart. This causes the anti-parties of matter to be throw away at incredible rates. This happens at consistent times. The large amount of gamma radiation let off by this is how Mr. Hawking now finds black holes. Another interesting concept of black holes is they are can be formed other ways than by the end of a star's life. Stephen Hawking and his associates found that any nuclear explosion can cause the birth of a black hole. Hawking stated that is all the ?heavy water?, a component used in nuclear weapons, was used to create a nuclear explosion a black hole the size of earth would be created. He also stated no one would be around to witness the creation. It would have been caused by the implosion of earth at a massive rate and the amount of energy produced by the nuclear explosion. This had me wondering. Stephen Hawking also stated that is a black how small enough not to disturb the orbit of earth existed close enough to earth that it's power could be harnessed to produce huge amounts of energy. This made me wonder if the same concept could be used, except with all the wastes materials on earth. I do not know the exact physics of it all, but from Mr. Hawking explanations it seemed like it might work. Black holes were also explained by Stephen Hawking as how they transcended time. Apparently the massive gravitational pull creates a rip in the space-time continuum. It is unknown what happens to matter when it is pulled into a black time wise. All matter will be ejected into space eventually as the black hole loses itself. The smaller a black hole, the more matter is ejected. It may be an odd happening, but because of the larger black holes are harder to detect than smaller black holes. Mr. Hawking stated of how if an astronaught gets pulled into a black hole the tidal forces would stretch him into a long piece of spaghetti like person. However, his life would not end in the black hole. Given enough time he would be eventually ejected into space as particles. All matter in a black hole will eventually be lost into space. The smaller a black hole is, the more matter is lost by the black hole. Stephen Hawking explained what is thought to have happened to a black hole when all its matter is lost. The hole in the space-time continuum would collapse and an explosion as massive as on of a supernova would happen. It would leave the tear in time. I wondered when the explosion would happen? Would it happen now, or ten to trillions of years from when it actually collapses. The tear in time where would it exist? Until an actual black hole is found close enough to us I suppose these questions will remain uninsured.
