Black Holes Essay -- Papers

Black Holes The term black hole was prototypal used in 1969 by the American scientist John Wheeler to delimitate an object that had such a huge gravitational pull that not eve illumine could escape it, thereby rendering it invisible or black. John Michell extended upon this idea in a paper called the philosophical Transactions of the Royal Society of London in which he pointed come on that a star that was sufficiently massive and compact would have such a strong gravitational pull that not take down dim could escape it as any light emitted by the star would be pulled back in by gravity - this was the first theory of a black hole. It is known today that black holes are in circumstance the fate of huge stars. When these huge s tars collapse they eventually collapse to a point where they are infinitely dense yet infinitely atomic - a black hole. Inside a star, hydrogen atoms are unendingly being fused to make helium atoms. This process is known as nuclear fusion, nuclear fusion produces energy in the forms of light and heat, the outward pressure that is created by this outpouring of energy is normally enough to offset the gravity that is constantly trying to squeeze the star ever smaller. shortly the star efforts out of hydrogen to burn and so begins to burn heavier elements (such as oxygen and lithium), when this happens the star will grow up to 100 propagation its original size. But eventually the stars supply of fuel will run out and the star will no... ...s a black hole. First, as you neared the even horizon, time would appear to take longer and longer and as you entered the even horizon your image would remain there for an eternity. This is because at that very moment , the light that you are emitting would be caught in the event horizon. It would appear to an observer that you were crisp in time, staying in the same position forever. But in detail it is just the light, not you that is stuck. As you entered the black hole time would go faster and faster, and if you looked up you would be able to see the entire innovation evolving in front of you. But this amazing sight comes at a great cost, as you begin to near the singularity you would feel your form begin to stretch. Eventually your body would be stretched so far by the colossal gravity that you would be ripped apart
