Black Holes: Forces of Gravity Essay

The existence of black holes was first theorized by John Mitchell in 1783. Mitchell accepted Newton’s laws of gravity and suggested that light escaping from the surface of a star would have its speed reduced due to the gravitation pull of the star, and therefore if a star’s gravitation pull was strong enough even light would not be able to escape.[1] Using the approximate speed of light he reasoned that if an object was approximately 500 times the mass of the sun light would not be able

No school in the country gets more research funding than Johns Hopkins, and as a result no other university would be able to provide me with as many incredible research opportunities. Although I am excited by the opportunity to learn new and fascinating information inside the classrooms of Johns Hopkins, my true passion lies in doing research during college. I have always been intrigued by mystifying concepts such as general relativity, dark matter, and black holes. The learning atmosphere at Johns Hopkins University will encourage me to pursue these mysterious subjects by working on research with the brilliant minds of professors and other

Black holes should probably not be called black holes. In fact, black holes are anything but empty space. Black holes are a great amount of matter packed and squeezed into a very small area. The result of this amount of matter squeezed into a small area results in a gravitational field so strong that nothing, not even light, can escape.

Prior to this symposium, physics was not very high on my interest list. However, due to both Dr. Neil Cornish and Dr. Nicholas Yunes, they ignited a strong interest in this field in me. Both professors discussed black holes and experimental tests on certain theories in an extremely enthralling manner. Not only were their presentations interesting, but they succeeded in altering my previous viewpoint on physics. Due to

“Black holes are perhaps the most exotic objects to impinge on the cosmic consciousness. They are formed when matter such as that from a dying massive star collapses in calamitously under its own gravity. forming a region of space in which the gravitational is so strong that it swallows all matter and radiation that come near it.” - Christopher Reynolds (Anderson, 2010).

Black holes are strange because we can not see them because they have such a strong gravitational pull light can 't escape from. They can rip anything apart. Black Holes form when a star dies and collapses in on itself. They are usually relatively small and really dense. Rather, it is a great amount of matter packed into a very small area - think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. In the milky way their are a few hundred million black holes. In recent years, NASA instruments have painted a new picture of these strange objects that are, too many, the most fascinating objects in space.

Black holes are a staple in the study of our unknown universe. The current understanding of general relativity allows something like a black hole to exist due to the strange properties surrounding them, as well as the effects on their surroundings. Black holes are defined by Chaisson's Astronomy as "a region of space where the pull of gravity is so great that nothing, not even light can escape" (Chaisson, 2013). This definition is very broad, simply stating the effects of what we call a black hole. Indeed, there is a lot of thoughtful assuming done when discussing this phenomena, however, what if everything we thought we knew about black holes was wrong and black holes didn't actually exists. That is exactly what a small group of scientists and astronomers think is the case.

Samuel had only just gotten inside when lightning flashed, thunder sounded, and the rain began to fall.

Coupled with new discoveries, black holes frequently cause series of events throughout a universe. According to The Gale Encyclopedia of Science, in their article titled, “Active Galactic Nuclei”, “Active Galactic Nuclei’s (AGNs) are located at the centers of some galaxies—perhaps most galaxies—and emit a tremendous amount of energy across part or all of the electromagnetic spectrum, sometimes on the order of trillion times the output of the Sun” (The Gale Encyclopedia of Science). In other words, AGNs are the center of the universe and can be violently energetic objects. Leading astronomers concluded that a super massive black hole was at the center of every AGN, and the main source of its power, containing a million to ten billion times the mass of the sun (The Gale Encyclopedia of Science). Eagerly,

Black holes are in theory incredible frightening. One of the main reasons they are so monstrous is that they are one of the only thing in the universe able to trap light. The second reason they are so terrifying is that when you are being pulled into one you will be on a one way ticket train to emptiness. Therefor if there was a way to get out of a black hole what would it be? Then also if there was no way out what would it look like on the inside? Well some of these questions can be answered easily but for the others it will be a little more troublesome to answer. This is how, what, and why black holes are formed.

The formation of supermassive black holes has been questioned in physics since the day of their discovery. Just how is something so large and powerful formed? Are they a danger to us? What lies beyond the event horizon? These are all questions that have been asked and not yet answered by astrophysicists. The first step to completely understanding these obscure creatures is finding out how they form, today's physicists are working endlessly to find an answer. Previous theories stating that supermassive black holes developed over time by ingesting large quantities of gas, have recently been found to be wrong. The most recent developing theory describes supermassive black holes forming by observing other black holes. There are two versions of

There is only one problem about black holes, scientists don’t know if they exist. Scientists have a ton of evidence on why black holes do exist. They discovered that stars are orbiting concealed objects in the galaxy. By tracking the movement of the stars that could be sucked into the black hole they can determine whether they’re real or none existent. Astronomers and scientists may have many clues for black holes existing but nothing they have found has confirmed that black holes actually exist.

But their could be a possible reason to get inside a black hole, but you can also get lost in space knowing you're in the middle of nowhere.Scientist and astronauts are trying to figure out how to get in a black hole without any risks by like simple making the space shuttle more and more advanced each time they go into space. Scientist are still working on finding out the process of black holes dying. Well the process is very simple when a black hole has eventually lost almost all of its energy from the stars it had collected it kind of starts to fade away and the next thing you no the black hole has had exploded and their is just a little star left.so what this whole reaserch essay was for the interesting facts about black holes and hoe they form and also how they live a long time and then they explode and becom a new baby star that then will become another black

Black holes, complex and difficult to understand, have intrigued both scientists and physicists alike since the eighteenth century. French scientist Pierre-Simon Laplace, born in 1749, was one of the first scientists to argue for the existence of an unexplainable body that encompasses an endless amount of space . Following Laplace, John Archibald Wheeler, an American physicist born in 1911, coined the term “black hole” for a space entity that is “so compact (in other words, has enough mass in a small enough volume) that its gravitational force is strong enough to prevent light” and all other matter from fleeing its body (What Is a Black Hole?). Black holes, therefore, are masses that have a gravitational force so great that they attract

Another method in physics on how to time travel is through black holes. A black hole has been discovered by Einstein's theory of general relativity, which showed that when a star dies, it leaves behind a small, dense remnant core. If the core’s mass is more than the sun, the force of gravity overwhelms all other forces in which it transforms into a black hole. Scientists have said that black holes can destroy anything that goes in it and it could be hard to get out of a black hole, once something went in it. In an interview by physicist Lior Burko, he states, “One possibility is that black holes may allow us to travel to very remote places in the universe, or another universe entirely,” (Kahney, “Black Holes and Space Time”). Black holes may have evidence that there are different kinds of parallel universe. Even though it is still unclear what black holes can do as in destroying everything that it goes in or if it leads someone to time travel into another parallel universe. Scientist are trying to create a black hole, here on earth, to see what blacks can do as in sending information to another universe.
