Recommended: Key to understanding black holes
When I was growing up there were things in life that always seemed to fascinate me. Most of them were usually science based. Things like elements on the periodic table, where did the stars come from and what lies at the end of the universe? I think the one question that always had my attention was what is a black hole. I can remember asking my parents when I was at about the age of eight or nine what a black hole was, and what was its purpose. Like most people, not really knowing themselves what a black hole was they kind of made up some wild crazy story hoping that I was to young to know the difference between fact or fiction. Later on in life I found myself still being driven by a lot of the same questions. Science to this day still remains as one of my favorite subjects, especially when it comes to astronomy. Finally, once I reached college I was able to take classes that interested me and that could answer a lot of my own questions. One question that I focused on a lot was were do black holes come from, how do they function and what drives them. Since having taken an astronomy class and researching the phenomenon of a black hole, I now have a much better idea and understanding of them. Believe it or not they can they can be easily explained. To start out, I want to put to rest a common myth about black holes. One that I was often told about as a child was that they are like a cosmic vacuum going around sucking up any and everything in it’s path. This is not true, but if an objects orbit should take its self close enough to the event horizon of a black hole then it would be unable to get out because of the intense gravitational pull. The origin of the name black hole comes from the idea that a black hole is a one way deal,... ... middle of paper ... ...e collapsing will be so dramatically compressed by the gravitational force that its density and gravitational field will become boundless. Some other theories are that maybe a black hole could be the gateway to another universe or that a black hole turns into a way for time travel, there has even been the idea of that what is being sucked in is then used for the creation of new matter. Either way there is not enough evidence for scientist to support these ideas with and since we it can not actually be observed what is really taking place beyond the event horizon of a black hole all we are able to do for now is wonder. Unfortunately for me I prefer to base my knowledge off of fact and not on someone’s theories, in my opinion a theory is know different than guessing. So while I was able to answer some of my questions I developed a whole new set of new ones.

The origins of the super-massive black holes which concludes how they were formed and what caused them to form is an unsolved problem which is yet a mystery of astrophysics. ( Millis 2014)
...f gas, which collapsed and broke up into individual stars. The stars are packed together most tightly in the center, or nucleus. Scientists believe it is possible that at the very center there was too much matter to form an ordinary star, or that the stars which did form were so close to each other that they coalesced to form a black hole. It is argued that really massive black holes, equivalent to a hundred million stars like the Sun, could exist at the center of some galaxies
The idea of Black Holes was first proposed in the 1700s by scientists John Michell and Pierre-Simon Laplace, who argued, independant of each other, that there might be objects in the universe with such a large gravitational force, that even light could be trapped. Published in 1916 Einstein’s theory of general relativity which included how gravity does affect light’s motion, gave way to scientific discoveries involving black holes. In Einstein’s own theory, he was only able to approximate the solutions to some of his own equations, however Karl Schwarzschild was able to provide the solutions. These solutions described objects like black holes that had such massive density that nothing could escape them. Schwarzschild theorized that if an object had such a small radius, that the escape velocity will be greater than the speed of light. Because as previously mentioned, nothing is faster than the speed of light, the object would be sucked into itself by it’s own gravitational pull, which would cause the object to disappear. What r...
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.
Black Holes are referred to stars, and nothing from light or any kind of matter is able to escape the gravitational pull of that Black Hole. Black Holes are the last of the line after Neutron Stars and White Dwarfs. Black Holes are about 10-15 more times/massive than the own Sun itself. When the Black Hole reaches its final "stage" they blow up into also known as a supernova. Most of the debris is left behind as well which fusion can no longer take place. The Black Hole will collapse or close on itself if no force is to the opposing gravity. Nuclear fusion creates some energy and some pressure with the Gravity of the Black Hole. So with no force, the Black Hole shrinks to zero volume. Black Holes pull in all kinds of matter. Black Holes are small, but you wouldn't think they would be. They may be small but they have the energy to suck things up into themselves. A usual diameter of a regular black hole is 4 times the diameter of the sun. With the cause of them being small, distant, and dark, they wouldn't be able to be seen or observed. Now if you get too close to one, you may die. So black holes are still a mystery to be solved. Black Holes are massive in weight and they get bigger the more matter they suck up/ absorb. Black Holes are like the sibling(s) to wormholes. Blac...
Before I begin to speak about black holes, I will have to explain what the white glowing specks in the sky are. Without a star a black hole could not be formed. In the beginning of a star life a hydrogen is a major part of its development. Stars form from the condensation of clouds of gas that contain hydrogen. Then atoms of the cloud are pulled together by gravity. The energy produced from the cloud is so great when it first collides, that a nuclear reaction occurs. The gasses within the star starts to burn continuously. The hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as carbon, oxygen, and helium are consumed. This chain reaction of explosions fuels the star for millions or billions of years depending on the amount of gases there are.
Black holes were originally thought to have only mere mathematical concepts. There was seemingly no possible way to compress any object into a space small enough to equal to its schwarzschild radius. Later however, astronomer Subrahmanyan Chandrasekhar calculated that stars much larger than our own sun should theoretically be able to collapse into a black hole (UTFC). A star is like a blown up balloon with the force of gravity trying to compress the balloon inwards and the air trying to push the balloon outwards. Likewise, stars are held in balance by gravity trying to collapse the star inwards going against the outwards pressure of the internal reactions of the star called nuclear fusion. If the star is big enough and the pressure inside quickly disappears, gravity would and should slingshot the star into a tiny point with near infinite density with an extremely strong gravitatio...
Einstein himself, working at Princeton with Nathan Rosen had discovered that the equations of relativity actually represent a black hole as a bridge between two regions of flat space-time, a phenomenon known as the “Einstein-Rosen Bridge”. Later on, in 1963, the New Zealand mathematician Roy Kerr found that if a black hole is rotating, a singularity still forms, but in the form of a ring, not a point. It was believed that in principle, a particle may be able to fall towards the singularity, but if at some point moved through the hole instead of the ring, the particle may not be lost forever. Therefore, with these theories in mind, a particle falling into a black hole will fall through the ring that the singularity has become, then going through the Einstein-Rosen Bridge, eventually being spewed out of the white hole into another space-time continuum.
As you can see we have been temporarily blinded from the truth by fictional things that are easy to believe and that we want to believe. There are so many incorrect theories and ideas and most of them are just plain ridiculous. Astronomy can be a very complicated subject, but it is very necessary to understand what really happens in our galaxy and out in the huge frontier we call space.
...e times the mass of the sun. In this case gravity is overwhelmingly strong and is able to crush the neutron star towards zero mass. The result is a black hole with a gravitational field strong enough to not even let light escape (Brusca, 2004).
...e realm of current science. We don't yet have a theory that can handle the conditions present at that time yet. However, from the era of inflation on, high-energy physicists and cosmologists are quite confident of the theory, as crazy as it sounds! In fact, this specific theory makes its own predictions regarding the exact distribution of fluctuations of the cosmic microwave background, which have so far been confirmed, though complete confirmation will have to wait until the MAP and FERMI satellites become operational later in this decade.
Black holes are the result of the death of a massive star, leaving behind a dense remnant core that eventually collapses to create a gravitational force so strong that nothing, including light, can escape the force. The theory that black holes existed started back in the early 1900s and since then astronomers and scientists have been trying to get a better understanding of them. This phenomenon has been a working progress for astronomers and scientists for many years and as we develop a better understanding of our solar system, the more likely it is to make a significant discovery that can answer some of the most difficult questions about our incredible galaxy and solar system. The more information we are able to acquire about our universe, the more questions we might be able to answer about our existence. With advancements in technology we may be able to see some significant discoveries and insights into the world of black holes.
Education has always been a very important part of the human life. Since the beginning of humanity, we have thrived on learning things especially figuring out new things such as the universe and the human experience itself. Various different explanations have dominated the human history in trying to educate about the universe and human experience and one of them is Science. It has always tried to question everything and to find an explanation of the unknown. In fact it is the unknown that has intrigued the humanity the most and science has been the leader in trying to provide explanations to these unknowns.
