Black Holes Essay Words | 8 Pages Black Holes The American scientist John Wheeler coined the phrase “black hole” in to describe a massively compact star with such a strong gravitational field that light cannot escape. When a star’s central reserve of hydrogen is depleted, the star begins to die Jul 17, · Almost from the beginning of astronomical observations of galactic bodies in the universe, it has always been thought that "the more massive the bulge, the more massive the black hole" which has led scientists and astronomers to reason that "somehow the formation and growth of galaxy bulges and their central black holes are intimately connected." Black Holes are the places in space where the gravitational pull or force is so strong that light can not even escape. Personally, I found Black Holes to be the most interesting and questionable thing we have discussed in Astronomy because of the lack of knowledge we, as humans, know about them

The following paper discusses such things. Before such a terrifying body as a black hole comes into existence, it starts off as a beautiful, bright star. Black Holes : A Mighty Void, Before this happens, they explode or detonate; they become supernovae supernova — singular.
Black Holes : A Mighty Void, Eventually, black hole essay, a constant outward pressure pulls at the stars. But, because of the destruction caused by the supernovae, nothing can go against gravity, and so this results in the stars collapsing in themselves. From there, black hole essay, budding black holes start to appear. The light from the stars become unable to escape the incredible gravitational pull of the growing black What is really the definition of a black hole?
A black hole is a point in space in which gravity pulls in a drastic matter that not even light can exit. We only take notice as stars around black holes act differently than other stars in space. We can only ask questions such like; when they were theorized? How big they are? How are they are created?
Are they actually black? Could they affect Earth in any way? Black holes are still being black hole essay and there are still many questions to black hole essay answered. A black hole can be any size. In fact it could be large or as small as an atom. There might be three types of black holes : stellar, supermassive, and intermediate black holes ; their mass is quite large Black holes are the most mysterious objects that modern physics predicted.
Event horizon is the edge of the black hole. If anybody attempts to cross the black hole he or she will never come back. The holes are involved in a broad range of astrophysical occurrence, including majority of the active events black hole essay the space. John Michelle, a Black hole essay mathematician, initially visualized black holes in He called them dark stars and his explanation was based on Newton's laws of gravity. Employing Newton's law of gravity, he argued that a suitably thick object would posses an escape speed that is greater than light's speed.
John was not sure if such objects exist. He later abandoned his studies on black hole essay objects. Polymath Pierre-Simon from Black hole essay conducted soon afterwards similar research. InAlbert Einstein introduced his concept of general relativity. This theory enabled the initial good explanations of black holes to be created, black hole essay. One year later Karl Schwarzschild came up with the initial mathematical description.
Currently it is referred as Schwarzschild black hole. It explains a black hole that is completely spherical and does not rotate. Karl Schwarzschild is recognized as a bright astronomer black hole essay discovered black holes This essay will explain what a black hole is along with how black holes can be detected and how black holes are formed.
Moreover, this essay will also provide evidence of the existence of black holes and locate where in the universe black holes occur. Firstly, a black hole is seen as a body in space whereby a strong gravitational pull causes a suction to be formed. The strength of the gravitational pull is so significant due to the different forms of matter being squeezed into a small hole which hence, creates pressure.
The event horizon is approximately 30 kilometres in diameter; there is no return past this. As a result of this, this conveys that many other objects in space such as dying stars or planets can easily disappear in black holes ; nothing is seen to be able to escape a black hole therefore, because of this there is no information black hole essay has currently been gathered by man.
However, with recent advance in technology, there may be missions in the Astronomers still have many questions regarding the darkest entity black hole essay space, black holesbut over time they began to analyze more and more clues and data, and are now able to explain what a black hole really is. Astronomers have come up with theories of the formations of black holesthe component of black holes as well as many other new discovered facts.
What is a black hole? There are many theories to this question. Some people believe it is a tunnel for time travelling, black hole essay, others believe it is a portal for teleportation. At this moment there are no scientific proofs to support these believes, black hole essay. There are still countless unanswered questions, black hole essay, questions like what is on the other end of the black hole, black hole essay.
Why they exist? Can astronomers fully understand them? These questions may never be answered but here is what astronomers believe. Scientifically speaking a black hole is an area of space that have abnormally large amount of gravity, so much gravity that not even light can escape, black hole essay. The matter the black hole attracts doesn't collapse into a single point, as has been predicted, but rather gushes out a "white hole " at the other end of the black one, the theory goes.
In black hole essay recent paper published in the journal Physics Letters B, Indiana University physicist Nikodem Poplawski presents new mathematical models of the spiralling motion of matter falling into a black hole. His equations suggest such wormholes are viable alternatives to the "space-time singularities" that Albert Einstein predicted to be at the centre of black holes. DIFFERENT THEORIES PROPOSED: According to Einstein's equations for general relativity, singularities are created whenever matter in a given region gets too dense, as would happen at the ultra dense heart of a black hole.
Einstein's theory suggests singularities take up no space, are infinitely dense, and are infinitely hot—a concept supported by numerous lines of indirect evidence but still so outlandish that many scientists find it hard to accept.
It is said that fact is sometimes stranger than fiction, and nowhere is this truer than in the case of black holes It has so much gravitational pull that nothing can escape from it, even light if it gets close enough. Albert Einstein predicted black holes back in The first black hole was discovered in by rockets that were carrying Geiger counters that came across eight new x-ray sources.
Scientists that detected radio signals coming from it found the black hole calling it Cygnus X There black hole essay three types: stellar black holes. Intermediate black holes and supermassive black holes. When a large star burns through the last of its fuel, it will collapse and fall black hole essay a small stellar black hole.
It has the mass of the sun into a city-size range, which creates an insane amount of gravitational force pulling everything inside of it. The dust and gas from the galaxy makes black hole essay holes grow. If you thought that was big, the supermassive black holes are millions or billions of times as massive as the sun. These are thought to be in the center of every galaxy like the Milky Way, black hole essay. In this quote, H. Wells asked one of the most commonly asked questions in time travel, why can people not move about in time as they wish?
Another way of traveling through time is through wormholes, which are tiny crevices, wrinkles, black hole essay, or voids in the fourth dimension, time. The final form of time travel that has some scientific credibility, black hole essay, is to travel at an accelerated pace through time, by traveling close to the speed of light.
Therefore, black holeswormholes, and traveling near the speed of light are all theoretically viable ways of traveling through time. According to Albert Einstein time is like a river speeding up and slowing down.
Einstein realized that gravity drags on time, slowing it down; and the greater the gravitational pull of the object, the greater the Sign Up. Sign In. Sign Up Sign In. Home Essays Black Hole.
