There are two types of black holes that exist in our universe. The first one being the Schwarzschild black hole which happens to be the simplest one of the two. This black hole is considered the simplest because its core does not rotate which means the black hole is completely stable at all times of the day. The next black hole is the Kerr black hole, which happens to be the most common in nature. This black hole in contrast to the Schwarzschild black hole does indeed rotate. When the rotating star dies out and collapses, the core continues to rotate and therefore, that carries over to the black hole. Scientists believe that the smallest black holes formed when the actual universe formed and began. They also have been led to believe that the supermassive black holes that exist in our universe were made at the same time as the galaxy that they …show more content…
He named it black holes because he continued to hear news of how there were dark regions in the sky that would suck matter into them so he came up with the term ‘Black Hole’. However, no one knew what exactly a black hole was and what it could do so they began to take hints and make predictions as to what they could be. Back in 1783, John Michell predicted that there might be an object massive enough in space that its escape velocity could be greater than the speed of light. Later in 1796, Simon Pierre LaPlace predicted that black holes actually existed as he stated, “It is therefore possible that the largest luminous bodies in the universe may, through this cause, be invisible.” He believed a black hole was invisible because since there is no light up in space, he thought they just blended in to their surroundings. The first black hole that astronomers could actually examine was found in 1970 and they named it the Cygnus X - 1. The black hole measured to be smaller than Earth and was detected by the x-rays it gave off on its outside
Many philosophers have said that the ‘Eyes are the windows to the soul.’ The eyes can show a person’s true personality. Not their clothes, facial expressions, or how they hold themselves, but looking into another’s eyes will show one’s soul. But what if their personality was not found in their eyes, but on their body in the form of a mutation? As found in Black Hole, the town’s teens have contracted an STD they call “the bug.” Each teen that acquires it grows an external mutation. This can especially be seen with some of the main characters: Keith, Rob, and Chris. Keith grows appendages that look like tadpoles on his chest. Rob has another mouth on his neck. Chris sheds her skin. Each of these mutations indicate what this person is actually like. The external mutations of Keith, Rob, and Chris symbolize the characters’ inner selves.
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
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
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 “…
A black hole is a region in space where the pulling force of gravity that is so strong that the region cannot escape. This compression can take place at the end of its stars life. Some black holes are a result of dying stars. How every space telescopes with special instruments can help find black holes. They can observe the behavior of material and stars that are very close to black holes. Black holes can come in a rage of signs, but there are three main types of black holes. The black holes mass and size determins what kind it is. The smallest ones are known as primordial black holes. Scientists believe this type of black hole can be up to 20 times greater than the mass of the sun and fit into a ball of about 10 miles. The largest black holes are called supermassive. Supermassive black holes are at the center of the milky way galaxy is called sagittarius. A black holes gravity can be as strong to pull off the outer layer gass of the star and grow a disk. The
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.
Stephen Hawking, when you hear his name you think about the scientist who studied space and has a disease. If you thought that, you are correct. Life was difficult for Stephen mostly when he got a disease called (ALS) amyotrophic lateral sclerosis. Even with his disease, Stephen accomplished a lot in life. Stephen Hawking is now known for his theories on black holes and the big bang. His studies have convinced many scientists to study what he did, which helped them learn more interesting things.
Stephen Hawking was a theoretical physicist who was, and continues to be a leader in his field even after his death. Born on January 8th 1942, Hawking began his career at the age of 17 at the University of Oxford. He then proceeded to attend the University of Cambridge where he would apply Roger Penrose’s theorem of a spacetime singularity in the centre of black holes to the entire universe which is known as the Big Bang. At the young age of 21, Hawking was diagnosed with a rare early onset slow progressing disease knows as ALS or Lou Gehrig’s and was given two years to live. He had three children with his first wife Jane Wilde including Lucy Hawking. Furthermore, Hawking is also well known for his best seller A Brief History of Time.
Heroes are not always the one who flies around saving the world from evil villains. Heroes can be ordinary people. Or people with brilliant intellects. Providing the world with newfound information about the Universe. Stephen Hawking is one such hero. Born in Oxford London, Hawking worked hard in his career to help make science able to be accessible to everyone, as well as becoming one of the most noticeable cosmologists since Isaac Newton.
Who was the person that had the theory of black holes? The man that discovered black holes was Karl Schwarzschild. He was born on October 9, 1873. It was the year 1916 when he made the theory of black holes a possibility. He was not the first to make the theory of a hole in space that might have the same qualitys of a black hole. The people who had this theory were John Michell and Pierre-Simon Laplace. They had this theory in the 18th century this was around the time that North America was discovered and when Britain had great
When I think of a person I admire, whether it be someone I aspire to become like myself or just find to be interesting, a person who comes to mind is Professor Stephen Hawking, a renowned physicist and role model for disabled people, especially for those with ALS, also known as Lou Gehrig’s disease. Stephen Hawking is known for his many works in the world of physics, such as Hawking radiation and his various other contributions in black holes, his theory of Cosmology, and his many discoveries in the field of Quantum Mechanics. He is also known for his best-selling book, A Brief History of Time: From the Big Bang to Black Holes, published in 1988. Hawking possesses many traits and skills that one could appreciate, but a few of them stand out.
The quote, “look up at the stars, not down at your feet,” spoken by Stephen Hawking at the Sydney Opera House, sums up Hawking’s life in one sentence. Despite having amyotrophic lateral sclerosis, or ALS, Hawking survived nearly fifty years with the disease until he died on March 14th, 2018. In the time period of him having the disease, he has made several large contributions to the field of science, and cosmology. The changes and influence Stephen Hawking has made will likely change the whole world for the better.
[9] He preceded on that instead of having objects disappearing into a black hole with no trace, he announced he believed that black holes can preserve information from objects swallowed up. "If you jump into a black hole, your mass energy will be returned to our universe, but in a mangled form, which contains the information about what you were like, but in an unrecognizable state." Hawking stated.[10] This tells us that nothing has ever completely disappeared in a black hole. Any objects that are sucked into black holes are completely mangled, but don't disappear. “He stunned the world with his findings about hawking radiation” a newspaper title read. [11]This theory also solved a lot of mysteries that have happened in space. It helped other scientists such as Roger Penrose continuing on with there other types of research so they could discover other new things now with this
Our universe is vast and filled with mystery. There are many things we still don’t fully understand. One of these are black holes. Black holes are still one of the most studied objects in outer space. These cosmic pits of darkness can hold secrets that help unlock so many unanswered questions.
According to NASA (2013), Princeton physicist John Wheeler coined the term "black hole" in 1967, but "the idea of an object in space so massive and dense that light could not escape it has been around for centuries." One of the ways that black hole research relates to life on earth is that studying black holes might offer clues as to why we are here. Science might have shelved the equation of General Relativity until the 1960s due to technological breakthroughs that allowed for greater exploration of space using revolutionary instruments; and also allowing for increased application of those equations in physics research. Karl Schwarzschild contributed to the science of black holes by developing special technologies, especially optics, that could help measure stars. He died of a "rare metabolic disorder," (Weisstein, 2007). Subrahmanyan Chandrasekhar discovered "there is an upper limit - now called the Chandrasekhar limit - to the mass of a white dwarf star." The research is important because it showed that stars more massive than the sun must either explode or form black holes ("Subrahmanyan Chandrasekhar," n.d.)
