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
collapse upon itself to form a black hole. This is mostly dependent on the density of the star. When massive stars, those twenty times the mass of our Sun or more die, they must either exhaust all of their excess mass or implode upon themselves and form black holes. Gravity overwhelms even the nuclear forces. The gravitational force becomes so strong that nothing can escape it, even photons of light, hence the name "black" hole. It is believed that large black holes may exist at the center of our
Black Holes The term black hole was first used in 1969 by the American scientist John Wheeler to describe an object that had such a huge gravitational pull that not even light could escape it, thereby rendering it invisible or black. John Michell extended upon this
Black Holes Every day we look out upon the night sky, wondering and dreaming of what lies beyond our planet. The universe that we live in is so diverse and unique, and it interests us to learn about all the variance that lies beyond our grasp. Within this marvel of wonders, our universe holds a mystery that is very difficult to understand because of the complications that arise when trying to examine and explore the principles of space. That mystery happens to be that of the ever elusive, black
In 1916, the German astronomer Karl Schwarzchild attempted to theorize how a star could shrink to become what he called a "Black Hole". Schwarzchild predicted that our sun would have to shrink to less than two miles in radius. He also predicted that even though the sun had shrunk its mass and weight would remain the same, which means that the planets would continue on their orbits, uneffected. Schwarzchild still questioned if stars could become this compact. In 1934 W. Baade and F. Zwicky predicted
Have you ever wondered what a Black Hole is, or what happens if you go into one??? Well now’s your chance to find out about them.There are many theories to Black Holes and if they are real or not. But Black Holes are real. Karl Schwarzschild is the founder and the theory master to Black Holes. Black Holes are mostly found inside of the Milky Way. There are many types of galaxies and many different types of Black Holes. A normal galaxy has gases and stars Black Holes are referred to stars, and nothing
Black Holes The American scientist John Wheeler coined the phrase “black hole” in 1969 to describe a massively compact star with such a strong gravitational field that light cannot escape. When a star’s central reserve of hydrogen is depleted, the star begins to die. Gravity causes the center to contract to higher and higher temperatures, while the outer regions swell up, and the star becomes a red giant. The star then evolves into a white dwarf, where most of its matter is compressed into
black hole, in astronomy, celestial object of such extremely intense gravity that it attracts everything near it and in some instances prevents everything, including light, from escaping. The term was first used in reference to a star in the last phases of gravitational collapse (the final stage in the life history of certain stars; see stellar evolution), by the American physicist John A. Wheeler. Gravitational collapse begins when a star has depleted its steady sources of nuclear energy and can
Black Holes Black holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole. Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Since our best theory of gravity at the moment is Einstein's general theory of relativity, we have to delve into some results of this theory to understand
To first understand a black hole, you must understand how it is created. Most black holes are produced by dying stars that have a mass twenty times greater than our sun. A star eventually becomes a black hole because the energy and pressure pushing outward is overcome by gravity that pushes inward. For big stars the gravity force causes a star to collapse under its own weight. The star then will explode as a supernova and some outer parts of the star are sent out into space. The core is still intact
there is one object that stands to elude scientists still, the black hole. Albert Einstein, and all the brilliant scientists after his, help to design and create a part of the universe that’s very crucial to understanding existence. The perimeters of a black hole have been a great this that has been discussed and observed to the point where it eventually becomes clear as its compared to objects around or like it. The physics of the black holes existence is still unclear for it shows properties that support
Understanding Black Holes A Black hole is a theorized celestial body whose surface gravity is so strong that nothing, including light, can escape from within it's surface. Gravity is the key to a black hole's immense power. The black hole's strong gravity keeps captured material from escaping. For example, if Earth were the same mass it is now but had only one-fourth its present radius, the escape velocity of someone standing on its surface would be twice what it is now. Black holes
thereby forming what is commonly known as a black hole, a point around which the gravitational force is too strong. Imagine a giant building, a skyscraper for example, being compacted and compressed to the size of a Rubik’s cube. This happens to the massive dying star at the end of its life. For nearly 200 years now, theorists have postulated the existence of black holes and now there is strong evidence to support that most, if not all galaxies have black holes that are essentially millions or even billions
space and have learned a lot with the technology we have. One of the main mysteries that we have not understood much is “the hole”. When I say “the hole” I mean the three main ones the black hole, white hole, and the wormhole. Each one is important in their own way, but this paper will be focused on black holes. I will briefly touch on theories that involve time travel, white holes, and wormholes. The scientist who came up with the name was John A Wheeler. John invented the theory of nuclear fission
The Creation, and History of Black Holes What is a black hole? How are black holes formed? And who first discovered black holes? Are all excellent questions that will be answered in this research document. However, before you are fed information on the history of black holes, you must first know the definition: A black hole is a region of space having a gravitational pull so intense that matter or light can escape. Black holes can be classified into 3 three categories based on their method of creation
Black holes are one of the many amazing unexplainable wonders around the world. Black holes are also very abundant in many galaxies especially the Milky Way. There is believed to be at least over ten million black holes scattered around the Milky Way galaxy alone. In every galaxy there is a supermassive black hole that is at least billions of times as big as the sun and it is big enough to swallow the whole solar system. The first black hole was discovered in 1971 and John Wheeler, an American astronomer
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
Black holes - the strange scientific phenomenon that has astounded physicists and astronomers alike for decades. Popular subjects in science fiction novels, black holes are one of the greatest enigmas of the scientific world. Even today, the concept of a super-dense ball of matter that not even light can escape from is somewhat farfetched, and many scientists disagree with each other about nearly every aspect of a black hole. This project will attempt to shed some light on these mysterious formations
Black Holes Black holes are points in space where there are extreme gravitational pulls that prevent anything, including light, from escaping. The reason for such a strong gravitational pull is due to vast amounts of matter being contained in a small amount of space. Stellar black holes form from stars with a mass greater than 20 solar masses and can be a result of gravitational collapse. Gravitational collapse is a result of the star’s internal pressure not being able to resist the stars own gravity
magnificent life of a black hole. The black hole is a mystery that you will want to learn about. A black hole does many wonderful things in outer space. Black holes in outer space have been a mystery for years. There are many questions such as how is a black hole born and how does a black hole grow. What is a black hole? A black hole is a dead star in outer space. It is where planets and stars disappear at. The gravity of a black hole is way too strong ( Aguilar 39). The black hole is a weird object
