You can escape a Black Hole: Surprising Informative Essay Have you ever taken the time to reflect and glaze upon the night sky, conjecturing and dreaming of what lies beyond our planet? Our universe also known as the Milky Way Galaxy is very miscellaneous and unique. With many marvelous wonders, the Milky Way Galaxy holds about mysterious belongings that are very challenging for human minds to understand due to the many complications that arise when we try to examine and explore the principles of space. One of the universe biggest mysteries is that of the ever indescribable, black hole. By definition, a black hole is a “celestial body so dense that light cannot escape its gravitational pull. It is formed when a star gravity causes it to collapse into itself.”(Oracle 1)There’s been a myth about black holes that has caught my attention and in this essay I will discuss such myth and explain the truths and false parts of the myth. Thus the myth states that once captured by a black hole there is no escape. For it is said that there is a great inward pull of gravity that is so overwhelming, which allows any matter or energy to disappear from the universe. In an article, written by Physics professor Tarun Biswas of Newpaltz State University, he provides details and examples on how can escape the unbreakable black hole. He stats, the “no escape myth has been believed by many individuals due to the misinterpretation of a feature geodesics within the black hole”(Biswas 1) Dr. Tarun explains that an object that enters the atmosphere of a black hole at any angle will be attracted greatly by the center of the black hole due to its geodesics (geometry of curves). Geodesic is defined as the shortest possible line between two points.

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...
Until recently, theorists believed that wormholes could exist for only an instant of time, and anyone trying to pass through would run into a singularity. But Khalili shows the reader that more recent calculations show that a truly advanced civilization might be able to make wormholes work. By using something physicists call “exotic matter,” which has a negative energy, the civilization could prevent a wormhole from collapsing on itself. Perhaps someday in the far future, wormholes will become a useful asset in universal transportation.

...ke for instance the two images below. The first is a two-dimensional representation of the gravity of a normal star. Imagine any object floating through space as a marble. Said marble rolling along the flat surface of the space will roll into the indentation made by the sun's gravity. If you flick the marble hard enough, it can roll out of the indentation and roll away. The second pic is a representation of the gravity made by a black hole. Notice that if the marble rolls into the hole, there's no way it can get out, since there is no end to the hole.
The idea of Black Holes was first proposed in the 1700s by scientists John Michell and Pierre-Simon Laplace, who argued, independant of each other, that there might be objects in the universe with such a large gravitational force, that even light could be trapped. Published in 1916 Einstein’s theory of general relativity which included how gravity does affect light’s motion, gave way to scientific discoveries involving black holes. In Einstein’s own theory, he was only able to approximate the solutions to some of his own equations, however Karl Schwarzschild was able to provide the solutions. These solutions described objects like black holes that had such massive density that nothing could escape them. Schwarzschild theorized that if an object had such a small radius, that the escape velocity will be greater than the speed of light. Because as previously mentioned, nothing is faster than the speed of light, the object would be sucked into itself by it’s own gravitational pull, which would cause the object to disappear. What r...
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.
These are the reasons why I believe there should be more investment in space research and technology. It would be a time consuming and financially draining quest, but the pay off in new technology, applications, resources, and expansion opportunities make it a goal to strive for. As our rate of consumption of Earth’s natural resources continues to increase, it is imperative that we invest in the research of outer space as a possible solution to sustaining the human race.
When considering this topic, one might ask themselves why explore space? We explore space to compare other planets with the earth and to study the sun, to explore the universe while finding if intelligent life exists, for satellites to improve communications, weather forecasting, navigation, resource monitoring, and “to create a focal point for a new intellectual renaissance” (Ruzic).
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.
“Let’s go mudding!” Exclaimed my fiancé Chris, as we piled into his big, muddy, white truck. The day before, it rained most of the evening. Priming the grounds for optimal fun. Excitement filled my body, as we made our way out to the mud hole. “You ready baby?” Asked Chris, with a cheeky grin. “I was born ready!” I replied smiling back. As we pull up to the field, I feel my heart start racing in anticipation. Once grass filled acres of land, showing signs we haven’t been the only one here today. Tire tracks, and big holes leading us out to the field where the real fun resides. As we turn the bend, the mud holes and hills are everywhere! I look at Chris and Smile, and off we go! Flying through the pond like puddles, throwing thick gritty
Many answers can come from exploring space. Getting a “few lumps of moon rock” can answer so many questions we asked ourselves for millennia. Can we truly belong in a place we do not know about? Space exploration will better us now and in the future for several reasons. The idea of travelling into the unknown has puzzled life since it could move.
Most people think that the costly downside to funding space exploration is a reason to avoid spending money on sciences and instead spend it on problems here on earth, but such funding for space exploration actually promotes economical as well as scientific benefits. Space exploration is an important expenditure for the high cost because of the potential for numerous benefits such as the possibility to find useful resources to cultivate, space exploration and satellites produce many thousands of jobs in our economy, and it creates and discovers newer and better technologies through research and development.
Space exploration is very beneficial to humankind because it creates new technologies, it brings different countries together, and gives people a better understanding of our Earth.
