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.
Death by Black Hole: And Other Cosmic Quandaries is a biography that is divided into 5 chapters total and a total of 42 mini sections. Bringing together more than forty of Tyson's favorite essays explores a myriad of cosmic topics, from what it would be like to be inside a black hole to the movie industry's feeble
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)
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...
...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
Such prospects are intriguing, and provide science fiction novelists with endless material for their writings. None of these theories have been proved, and since we can't get close enough to a black hole to study one, they're all perfectly valid. Perhaps one day mankind will discover the truths behind black holes.
A Black Hole is defined as an object in space that is so compact, that has a gravitational pull so powerful, not even light can escape its pull. In most cases Black Holes are formed when a massive star (much larger than our own) undergoes a supernova explosion. When this happens, the star may collapse on its own gravitational pull, thus resulting in a an object with infinitely large density and zero volume. As a result, the escape velocity (the speed required to escape the gravitational pull) becomes even greater than the speed of light, and because nothing can travel faster than the speed of light, nothing can escape a black hole.
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...
Every day we look into the night sky, wondering and dreaming what lies beyond our galaxy. Within our galaxy alone, there are millions upon millions of stars. This may be why it interests us to learn about all that we cannot see. Humans have known the existence of stars since they have had eyes, and see them as white glowing specks in the sky. The mystery lies beyond the white glowing specks we see but, in the things we cannot see in the night sky such as black holes.
...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).
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.
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.
...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.
