Black Abyss
Black holes make up some of the most mysterious objects in space. Black holes go around our way of thinking by generating mind­bending illusions and defying physics. They possess different laws that to any ordinary human being would seem impossible. Since their discovery, scientists conduct experiment after experiment trying to unlock their greatest secrets.
Bundles of information has been discovered about these dark, massive holes in space, but even the greatest minds in the world can not debunk them.
The idea of black holes appeared in the eighteenth century by John Michell and
Pierre­Simon Laplace, but the term black holes did not come until 1969 by an American physicist John Wheeler. John Michell and Pierre­Simon believed that if an object in space fit the size and density criteria, it would then have a gravity so strong that nothing could escape its pull
(
“How Do We Know That Black Holes Exist?”)
. For example, if you live on Earth, you would need to travel at least seven miles per second to escape its gravity, but if you dwell on the sun you would need to travel 380 miles per second to escape its gravity. Black holes get so large and dense that an object would need to travel faster than the speed of light to escape it ("Black
Hole,"
UXL Encyclopedia of Science
). As of today nothing can travel faster than the speed of light, so if you get too close to a black hole, goodbye.

Black holes form only when stars two to three times the mass of our sun die and create a supernova. As a star’s nuclear fusion, the bonding of hydrogen atoms to create energy, fails; it can no longer control its gravity and starts to collapse on itself. The point where all of its mass gets compacted is called a singularity.…...

...According to the article Black holes first, galaxies second it has been found out that each galaxy has a black hole in the center (16). By observing motions of gas it had been suggested that early galaxies were 30 times as huge as central black holes. Therefore, it has been suggested that galaxies are formed around black holes (16). Doppler shifts show the black hole mass. Astronomers believe that both the hole and the galaxies can stop growing (16). As stated in Spinning Hearts of Darkness “Astronomers are measuring the rotation rates of black holes to determine their rotation and history” (Brenneman, 20). A black holes’ gravity is so strong that light can’t pass through it (20). As stated in the article Black holes are neither let in light or let it come out (Brenneman, 21). Black holes can be up to billions solar masses. Measuring a black holes spin is important because it can tell us about its history (22). Black holes that occur because of mergers with other black holes will grow slower than those that occur by accretion. As stated in Brenneman “Black holes occur at random angles which alter the spin direction and speed of resulting black hole”(22).

Black Holes

...Electromagnetic Fields, Telescopes and Black Holes Astronomy is defined as the scientific study of the universe and the objects in it, including stars, planets, nebulae, and galaxies. Astronomy deals with the position, size, motion, composition, energy, and evolution of celestial objects. Astronomers analyze not only visible light but also radio waves, x-rays, and other ranges of radiation that come from sources outside the Earth's atmosphere (American Heritage Dictionary, 2002). This particular assignment required we visit an institution that specializes in the education of astronomy so that we, as students, could delve deeper into the world of astronomy through hands on experience. I elected to visit the Denver Museum of Nature and Science on the 4th of July 2012. I also viewed the film Black Holes the Edge of Infinity in addition to the hands on exercise. I feel a new appreciation for astronomy through the interactive learning experience because it put how very far we’ve come to understanding our universe into perspective. The first exhibit I visited had to do with the four nonvisible wave lengths of light and telescopes. I integrated the two exhibits so that I can elaborate on them in a way that culminates the experience. For every nonvisible wave measured there is a corresponding telescope. These are radio waves, infrared, ultraviolet, and gamma ray. Because radio waves are larger than optical waves, radio telescopes work differently than optical telescopes. Radio......

A Look at Black Holes and Their Counterparts

...A LOOK AT BLACK HOLES AND THEIR COUNTERPARTS For as long as the Earth has been around, humans have looked up in awe at the night sky and wondered about the intricate pieces that make up what is our universe. For most of Earth’s history, the universe only encompassed what was visible to the naked eye. In 1609, however, everything changed when telescopes were invented and the realm of the universe opened to unveil new and mysterious aspects never before seen. Interestingly enough, though technology has grown to gigantic proportions, there is still a lot we don’t know about the universe, and black holes, white holes, and wormholes are just a few of the aspects we still have much to learn about. At this point in time, astronomists have yet to actually see a black hole. So how do they know that black holes do in fact exist? And how can they deduce that related beings like white holes and wormholes do (or do not) exist? Through careful deduction and intensive examination, scientists like Einstein, Stephen Hawking, and many others have been able to give insight into the deep, enigmatic universe and exactly what these mysterious beings are all about. Einstein's general theory of relativity describes gravity as a curvature of space time caused by the presence of matter. If the curvature is fairly weak, Newton's laws of gravity can explain most of what is observed, for example, the regular motions of the planets. Very massive or dense objects generate much stronger gravity. The......

Black Holes and Their Mysteries

...Black Holes and Their Mysteries Black holes are one of the most popular Hollywood science fiction topics also one of the most mysterious entities in space. Astronomers still have many questions regarding the darkest entity in space, black holes, but 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 holes, the 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 traveling, others believe it is a portal for teleportation. At this moment there are no scientific proofs to support these believes. There are still countless unanswered questions, questions like what is on the other end of the black hole. 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. There is no certain explanation of the formation of black holes. However astronomers currently have very solid theories of how they are formed. One of which is the theory that is stated by Stephen Hawking claiming that “trillions of black holes were produced in the Big Bang, with some still existing today.” The main theory for larger......

Black Holes: What Do We Know?

...Black Holes: What Do We Know? Carl Antoni Everest University Abstract Answering the questions we have about black holes brings us closer to understanding them and the many ways they can benefit us. They give us clear insight on Einstein's law of relativity, help create cutting-edge technology, give us extraordinary insights to the universe and most of all it gives us amazing journeys of imagination where we can contemplate their amazing properties. The mysteries of the black hole exemplify the beginning and the end of everything science has discovered out in our vast universe. Beginning with Newton's law of gravitation, Einstein's law of relativity and expanding to supermassive black holes with infinite density and infinite gravity. A supermassive black hole has the mass of 1,000,000 to 1,000,000,000 of our Suns. There are smaller black holes but the smallest has to have a mass of at least 10 of our Suns. It is this mass that creates the immense gravitational tides that compress a giant star into an incredibly small entity that has such a tremendous gravity that not even light can escape. How is this possible? How are they created? How do we know they are there if no light escapes from them? Is there more than one universe? Is there such things as wormholes that can connect vast distance of space and time? These just a few of the provocative questions black holes inspire. What are Black Holes and what do they mean? Science has made many......

...Holes This novel’s author is Louis Sachar and their also is a movie out that is also called holes. The part of the story I was reading was at the time Zero or Hector Zeroni. Zero whacks one of the guards with his shovel. Then the next day Zero runs away from the camp called camp Green Lake which used to have a lake a few hundreds of years ago. After a week Stanley Yelnats, a fat and long kid who is not really that strong runs away too because he wants to find Zero. After walked about five miles he found Zero sitting in an upside down boat. Then he found him eating something that smelled like peaches and then Zero said,” I call it sploosh”(Sachar 166). He gave Stanley the last jar of sploosh and then they both got up and went to something that looked like a thumb. About 30 minutes later, they got to the mountain and started climbing it hoping to find water. About half way up th mountain they start seeing bushes and as higher they go the healthier the bushes look like. Then An hour later of climbing they reach the top of the mountain. By the time they reached the top it was midnight. Ney reach the top Stanley says, “It was a good thing we found this mountain that looked like a thumb”(170). The next day they bothe start to pull out the flowers and find that they are onions. And they start to notice some water coming out of a hole so Stanley gets the shovel and digs a hole and finds water. 3 days later tanley says, “I think we should go back ton camp”(185)....

Black Holes

...Black Holes – Bending Time and Space Authors Note Explaining this phenomenon would literally take hundreds of pages, so I will try to be brief but yet provide meaningful explanations. It must be noted that some details must be dealt with in an abstract manner to avoid intricate mathematical explanations. Theory Definition Black holes are considered by many to be the most bizarre objects to ever exist in this universe. It is a theorized phenomenon in which an object or a region of space possesses an overwhelmingly large gravitational force to the point where even light gets pulled inside the hole. Generally speaking, for a region of space to possess a large gravitational field, it must be very dense in terms of mass concentration. Just like the name suggests, a black hole, in reality, is indeed black colored. This is due to the fact that neither matter nor light can escape from it, rendering the surface area of the hole being black. Black holes generally form when massive stars collapse at the end of their life time. History Background 19th century: English geologist John Mitchell suggested it would be possible that a gravitational force, extraordinarily large, could in fact bend and pull light. This judgment led other scientists later to relate the Newtonian gravity as they knew it, with time, light, and massive objects. 20th century: It wasn’t until the genius of Albert Einstein came around with his general and special relativity theories that we have had a......

But since 2009 (my last year in high school) a lot has been changed about the subject. Stephen Hawking even said in 2014: "Notion of an 'event horizon', from which nothing can escape, is incompatible with quantum theory." First of all, I'll shortly speak about Stephen Hawking himself. Then the real text about all his work can be started. I'll first introduce the birth of a star followed by its evolution till its death. Then the concept of "black hole" will be initiated. I'll write a chapter about the critics who were made about his work and eventually I'll resume everything in a short last paragraph. 2. Main part 2.1. Stephen......

Black Holes Evidence

...So what exactly are black holes? Lets put it this way. A black hole is just another thing a star can turn into when it runs out of fuel, in this case it is simply a massive ex-star that has collapsed. Black holes are very interesting and the properties that define them are how they are in mass, size, and what makes them black, how they are created, how they are observed. The creation of black holes is very interesting in my opinion. Basically you have a star with “critical mass” that has collapsed under its own weight until it became a black hole. If the star is heavy enough, it can develop into a black hole. Due to its density the star makes a dent in space-time curvature that is infinitely long. Because of this, it is very possible that they play an important role in galaxy formation and evolution according to scientists. But why is a black hole black? The reason for this is because the escape velocity of a black hole, which is the speed needed to leave the earth, is greater than the speed of light therefore the photons cannot leave. The explanation is fairly easy, light does not have a high enough speed to leave a black hole so it cannot escape. Think about shining a flashlight on a black hole. This would be useless because when flashlight photons hit an object, we only see the because they bounce off the object . In this case though, the photons of the light will just fall into the black hole and never come back out. The same with stars because we cannot see light......

...very scary in this book. Being with friends can help. Stanley Yelnats did not always have friends. At the beginning of Holes, Stanley was scared, but because of Zero he was brave by the end. Stanley was scared in the beginning because he did not know anybody. He was the new guy at Camp Green Lake. He had to go to the camp because they thought he has stole shoes, but he did not steal them. He thought he was going to get hurt. When he was in his cot, he thought it would break. Stanley was afraid of what would happen because of the curse. The curse was from his “no good, dirty rotten, pig stealing, great-great grandfather”. The curse would effect Stanley’s life immensely. Stanley was very scared because of all the things at Camp Green Lake and he did not have any friends to talk to in the beginning. At the end of the book, Stanley was brave because of Zero. Zero helped him have confidence. Everyone at the camp trusted Stanley. One of the campers named Squid asked Stanley to call his mom and apologize for him. Stanley taught Zero how to read and write even though other campers made fun of him. Stanley found his way back to camp with the help of Zero. They did not have any water, only had onions to eat, had to walk really far and they were alone. Zero and Stanley help each other even in the worst times possible. At the beginning of Holes Stanley was scared, but because of Zero he was brave by the end. This impacts Stanley’s future because he doesn’t have......

Black Holes: the Epic Mystery of Space

...Professor Bodus Astronomy Matthew Ryan Scott December 6th, 2015 Black Holes: The Epic Mystery of Space Black Holes: The Epic Mystery of Space The one aspect of space that provides a sort of horror element to the universe, to me, has always been the Black Hole. There is a very deep mystery surrounding Black Holes, and that uncertainty is very scary. Last year, my wife and I sat down on a Friday night, with pizza, and began watching the amazing movie, Interstellar. The one aspect of that film that still resonates with me is the mystery of the nature of the inner workings of a Black Hole. On that note, today, I would like to dive deeper into the research of Astronomers to have a better understanding of these wonders of space. The reality of a Black Hole is that it is not actually empty space at all, but rather a large amount of matter squeezed into an extremely tiny space. If we look at the many theories surrounding the existence of Black Holes, then it is presumable that a Black Hole is the most powerful force in all of our known universe, and beyond. It is widely known around the world, that the majority of people are familiar with the term “Black Hole”, but the reality is that the majority of people know next to nothing about them. Black Holes are formed when a star basically runs out of the fuel to keep burning. A star will begin to collapse under the sheer force of its own gravity after it has ceased to continue burning off gases (Frost, www.quora.com). A good......

Blace Hole

...BLACK HOLE A black hole is a theoretical region of space in which the gravitational field is so powerful that nothing, not even electromagnetic radiation (e.g. visible light), can escape its pull after having fallen past its event horizon. The term derives from the fact that the absorption of visible light renders the hole's interior invisible, and indistinguishable from the black space around it. . The idea of an object with gravity strong enough to prevent light from escaping was proposed in 1783 by John Michell, an amateur British astronomer. In 1795, Pierre-Simon Laplace, a French physicist independently came to the same conclusion. Black holes, as currently understood, are described by the general theory of relativity. This theory predicts that when a large enough amount of mass is present in a sufficiently small region of space, all paths through space are warped inwards towards the center of the volume, preventing all matter and radiation within it from escaping. While general relativity describes a black hole as a region of empty space with a point-like singularity at the center and an event horizon at the outer edge, the description changes when the effects of quantum mechanics are taken into account. [pic]Name The term black hole to describe this phenomenon dates from the mid-1960s, though its precise origins are unclear. According to Einstein’s general theory of relativity, as mass is added to a degenerate star a sudden collapse will take place and the......
