Essay about black holes.

Black Holes Within our galaxy alone, there are millions upon millions of stars. Within our universe, there are millions upon millions of galaxies. Humans have known the existance of stars since they have had eyes. Although interpretations may have differed on what they were, they were always thought of as white glowing specks in the sky, but the mystery does not lie within what we can see, but what we can not see. There are billions of stars lighting the darkness of our universe, but the question lies in what happens when one of these enormous lamps burns out. Upon many speculations, one of the most facinating is the black hole theory. Not any star can become a Black Hole. For instance, the possibility of our sun becoming a black hole.. more content... Even though a black hole's gravitational pull is enormous, it does have its boundry. This boundry is called the &quot;event horizon&quot;. This event horizon is the point where the black hole's gravitational pull begins. Once you cross the event horizon, there is no turning back. As stated before, the escape velocity of a black hole exceeds the speed of light, and since going faster than the speed of light is impossible, so is escaping a black hole's gravitational pull. This explains why all the black holes do not swallow everything up in the universe. Inside the event horizon is where the major speculation begins, just what happens once you cross the event horizon. Well, once you cross the event horizon, you'll be spinning around the center at the speed of light. As you get closer to the center, or what scientists call the &quot;singularity&quot;, the theory of the speghetti effect comes into play. That is, the gravitational pull of the center of the black hole is greater at your feet than your head, thus pulling stronger at your feet, and stretching you out to a point of infinite thinness. This same force is what causes the tides in our ocean, hence the name &quot;tidal forces&quot;. The time in which it takes you to witness this effect depends on the size of the black hole. A smaller black hole means that

Black holes: forces of gravity essay.

Science has always been about analyzing the hard facts in front of you, even if they might be invisible to the naked eye. Sizable leaps in our understanding about the mechanisms of life and our universe are in the process of being made with scientists believing black holes are the major precipice to these greater understandings. Black holes push and break many modern understandings of physics and time with many mysterious qualities. Insuppressible forces of nature, black holes, are a little understood entity in our universe with a strong influence on modern science. Despite modern culture and its influences on the unknown, a black hole is not a well understood concept even by the greatest of minds. Robert Prigo describes a black hole as "..... more content... Light is the fastest entity in the known universe, making black holes the strongest known object. At least knowing how big one is would allow for some creativity, but describing a black hole's size is yet another issue. When you're trying to ask someone how big something is you're going to be referring to the space it takes up. In this regard, a black hole can range from being smaller than an atom, to millions of times larger than our sun, or really any size in principal. "Any amount of mass at all can [...] be made to form a black hole if you compress it to a high enough density." (Bunn) Density, the compactness of an object, is a better way of describing a black hole because the way we think of size has no meaning here. You could also talk about its mass, or the sheer amount of material inside of it, but that is hard to quantify. For example, a black hole the size of an atom may contain all of the masses of our greatest mountains, but you can imagine something like that must be very dense. Either way, there are two common models for what a black hole could look like. If a black hole is spinning, then it's likely that the material inside of it is being compressed into a rotating disk of particles. On the other hand, a regular black hole is likely just to be a perfect sphere. Anything outside of the black hole's insides may also display unique properties, such as giving off electricity, emitting radiation or streams of light, and debris may orbit the

Informative Essay: What Are Black Holes?

It's a trap. Our universe, even our galaxy, contains many things that we do not fully understand. Part of this is the massive scale, the huge size that everything is when we compare it to ourselves. This means that many things are out of our realistic reach at this time. We cannot observe things in person. Some bodies, we would not be able to see even if we were standing on top of them. One of these such things are black holes. Physicists theorize that they exist, but they are still hard to understand. Not much is known about black holes, but being conscious about them could be crucial. It is hard to describe these elusive entities. Physicists agree on a definition, an incredible amount of mass in a single space that has such a large gravitational.. more content... Black holes are formed when massive stars collapse under the weight of their own gravity (Schoolworkhelper Editorial Team). The nuclear fusion in younger stars creates a constant outward pressure from the core ("Black Hole Images, Facts and Information"). This balances the pull from the gasses in orbit around the core, keeping the star stable (Schoolworkhelper Editorial Team). Once a star's life is nearing the end, and its gasses have almost all been used up in the nuclear reactions, the star will collapse inward from the gravitational pull without the outward push of the reactions (Schoolworkhelper Editorial Team). This happens to stars of at least six to eight times the mass of our sun (Schoolworkhelper Editorial

Black Holes : A Black Hole

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. Scientists do not have the ability to directly observe black holes with telescopes that detect x–rays, light, or other forms of electromagnetic radiation. However, Scientists can infer the presence of black holes and study them by detecting their effect on other matter nearby. If a black holes passes through a cloud of interstellar matter, it will draw that matter inward in a process known as accretion. A similar process will occur if a black holes passes a normal star. So, after a black hole is created, it draws in anything in its path adding to the extreme amount of matter that is packed into that very small area. Common types of black holes are produced by certain dying stars. A star with a mass greater than 20 times the mass of our sun can produce a black hole at the end of its life. Black holes are usually only created by the death of a very massive star. When a very massive star dies, it explodes into a supernova. The outer parts of the star are launched violently into space while the core completely collapses under its own weight. If the core remaining after the giant explosion from the supernova is very massive, there

Black Hole Research Papers

Black Holes This paper will introduce you to the incredible topic which is black holes. A black hole is a region of space time exhibiting such strong gravitational effects that nothing can escape from inside it. (NASA) No human has ever entered a black hole and there is still a large mystery about them; we have very little idea of where the matter that enters them goes. A black hole cannot be looked into either, as it sucks all the light into the middle of it. Space programs use special satellites with certain features that allow them to see these black holes. A black hole can be big or small, sometimes forming when a star is dying. Some scientists speculate that there can be black holes just 1 centimeter large. There are multiple types of.. more content... Scary right? Well what about a black hole sucking in the earth, is it possible? Thankfully, black holes do not go around eating stars, moons, and planets. There is no black hole close enough to the earth for it to be able to be sucked into. If a black hole the same mass as the sun were to replace the sun, earth would still not be able to fall into it. The black hole would have the same gravity as the sun and the planets would orbit it, just as they do the sun. Also, the sun will never turn into a black hole, as it is not a big enough star to create one.

Black Hole Research Paper

First the mystery of the black holes and how they were created goes way back to when astronomers first discovered them. The astronaut said "he saw a blob of black matter and black holes are made when a star burns out or explodes but the astronaut never truly saw the actual thing. Black holes absorb light particles that are close enough to it so that it can thrive and continue. When a black hole goes away the light that it absorbed is turned into a new star. When an astronomer found a black sphere shaped cloud of matter in space he didn't really see it but he saw it pulling in large amounts of light that have been destroyed from an exploded star. If anything but light matter happens to get into a black hole it would just go through it rather.. more content... The scientist said "light matter was being absorbed by the black hole,two different black holes come in contact then the larger of the two will shoot the other away somewhere else so it can create a star somewhere else. When a black hole absorbs enough light then it will become a new star and start the process over again. After that, gravity will drag you toward the singularity at the speed of light and ultimately spaghettify you. Gravity's strength is determined by the mass of the object its pulling and then the pulling strength gets greater. This also means that you would be stretched to fast if you happened to enter a black holes gravitational pull. Closer to the center, gravity is even stronger. If you were caught by the pull of a black hole, you would be sent into free fall toward its center. "Next if the Earth was hit by a black hole then it would stop spinning suddenly, the atmosphere would still be in motion with the Earth's original 1100 mile per hour rotation speed at the equator"(Black Hole). All of the land masses would be wiped clean of

Black Holes Essay

Black Holes 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. 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.. more content... If the remnant of this giant exploding star is larger than three solar masses or ten times our sun, it becomes a black hole. A black hole is one of the last option that a star may take. In the 18th century scientists started to research the after effects of a large star such as a supernova exploding. What happens of the gas and dust left behind after such a big star died? The idea of mass concentration so dense that even light would be trapped goes all the way back to Laplace in the 18th century. The first scientist to really take an in depth look at black holes and the collapsing of stars, was a professor, Robert Oppenheimer and his student Hartland Snyder, in the early nineteen hundreds. They came up with the basics of a black hole from Einstein's theory of relativity that if the speed of light was the most speed over any massive object, then nothing could escape a black hole once in its grasp. These researchers showed that when a "sufficiently massive star" runs out of fuel, it is unable to support itself against its own gravitational pull, and it should collapse into a black hole. In general theory of relativity, gravity is a manifest of the curvature of the space–time. "Einstein general theory of relativity showed that light, though it does not react to gravity in the same way as ordinary matter, is nevertheless affected by strong gravitational fields. In fact, light itself cannot escape from inside this
