You may think that black holes are just empty space, but they are far from it. Black holes are a lot of matter squished into a smaller area. The black hole then creates a sort of gravitational field that is so powerful, even light can not run from it. The black hole forms when a big enough star dies. This is usually the last stage of the death of a star. The first stage when the star turns into a white dwarfs then if it is big enough, it will create a supernova and explode. The explosive parts and the gravitational pull fight with each other and depending on the size of the star, it creates a black hole. With the dead remains of the supernova explosion, the star collapses onto itself to create a black hole. Because no inertia controls the gravity, the black hole becomes infinitely dense. The person that created the term black hole was by a physicist named John Wheeler, who founded it in 1967. Black holes are invisible because light cannot escape, so scientists can detect the effect from nearby objects in space. Astronomers find black holes by using radiation to find dust near it. Black holes are classified by three properties, mass, spin, and magnetic field. The three mass classes of black holes are stellar, supermassive, and intermediate. Stellar black holes are formed when an amount of small, but dense stars collapse. The result of the collapse creates an enormous amount of gravitational pull that it sucks up all dust and gases from space. These black holes are about three times the mass of the sun. Supermassive black holes are billions times as massive than the sun. There are three possible ways a Supermassive black hole could be formed. The first way is when tiny black holes form together. The second way i... ... middle of paper ... ...iation destroying the information, it is contained in stimulated emission of radiation, which is in the Hawking radiation, and this radiation glows whenever information is taken by the black hole. Then, the LASERS (Light Amplification by Stimulated Emission Radiation), create another copy that is left out of the black hole. These two scientists are arguing over the information paradox, which is the fight over the theory of the possibility that black holes can attract information. This argument has been going on between many scientists for several decades. All these theories, though are only supported by mathematics and physics, not by actual experimentation. Therefore, we can’t tell for certain if these theories are even slightly correct. Hopefully, we will be able to analyze black holes even further and be able to fully understand these spectacular objects.
Black holes are thought to be a portal to another dimension or a way for time to slip. Mainly all these theories follow the laws of physics and do not cross any illogical possibilities. For a way in which we can achieve any of these would be through many more years of research. If even physically possible for any of these hypotheses to coexist with one another. Learning that there’s a possible way for black holes to allow time to lapse or elapse. The study has been a challenge, finding ways in which these ideas could work. Theories about space time are not always true, but they allow us to have an improved understanding towards the, what ifs.
This book is more than just a series of explanations of current astronomical theories and research tools, however. Dr. Tyson injects a great deal of historical perspective as well as his own personality and humor throughout the narrative, which is what really makes the difference between text that would otherwise be just informative and a book that is engaging and entertaining to read. For example, when discussing how astronomers use the different regions of the electromagnetic spectrum, he writes, "Superman, with his x-ray vision, has no special advantage over modern-day scientists
With the upcoming brand-new installment in the legendary and beloved Star Wars saga, I decided to give props to some of the greatest sci-fi movies to ever grace the silver screen. All of the movies on this list either influenced or were influenced by the Star Wars franchise in both large and small ways. Of course, this list is my own opinion; feel free to share your ideas in the comments or yell at me on twitter.Event Horizon is a 90's horror film set in deep-space that includes fantastic performances from stars like Sam Neill and Laurence Fishburne. A salvaging crew is commissioned to find a lost craft called the Event Horizon designed by an eccentric Doctor played by Neill. The craft disappeared into a wormhole and when the salvage crew goes
Starting with black holes, Khalili describes the creation of one. I found that a black hole is what remains when a massive star dies. Because stars are so massive and made out of gas, there is an intense gravitational field that is always trying to collapse the star. As the star dies, the nuclear fusion reactions stop because the fuel for these reactions gets burned up. At the same time, the star's gravity pulls material inward and compresses the core. As the core compresses, it heats up and eventually creates a supernova explosion in which the material and radiation blasts out into space. What remains is the highly compressed and extremely massive core. The core's gravity is so strong that even light cannot escape. This object is now a black hole and literally cannot be seen because of the absence of light. Because the core's gravity is so strong, the core sinks through the fabric of space-time, creating a hole in space-time. The core becomes the central part of the black hole called the singularity. The opening of the hole is called the event horizon. Khalili describes that there are two different kinds of black holes:
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...
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)
Imagine a massive celestial object in space, so densely packed with matter that nothing can ever escape it, not even light- that’s what black holes are. They are formed by large stars- stars that are way larger in size (20 times or more) than the sun. When such massive stars run out of fuel in its course, it can no longer sustain its heavy weight. They rapidly collapse causing colossal of explosions called supernova.
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. When the star is exhausted of its nuclear fuel such that it cannot maintain a high enough temperature it will begin to collapse under its own weight (Seidel 2011). As the star collapses it causes a supernova which blasts the outer layers of the star into space while the core completely collapses under its own weight. If the remnant core left behind exceeds 3 solar masses there are no known forces that can prevent the core from completely collapsing into a black hole (p. 568 Bennett et al. 2013)
...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.
A black hole is created from a sun going into a supernova. It starts in the middle of the sun. Its mass collapses on itself to create a super nova. Once the supernova happens ...
Black Holes are referred to stars, and nothing from light or any kind of matter is able to escape the gravitational pull of that Black Hole. Black Holes are the last of the line after Neutron Stars and White Dwarfs. Black Holes are about 10-15 more times/massive than the own Sun itself. When the Black Hole reaches its final "stage" they blow up into also known as a supernova. Most of the debris is left behind as well which fusion can no longer take place. The Black Hole will collapse or close on itself if no force is to the opposing gravity. Nuclear fusion creates some energy and some pressure with the Gravity of the Black Hole. So with no force, the Black Hole shrinks to zero volume. Black Holes pull in all kinds of matter. Black Holes are small, but you wouldn't think they would be. They may be small but they have the energy to suck things up into themselves. A usual diameter of a regular black hole is 4 times the diameter of the sun. With the cause of them being small, distant, and dark, they wouldn't be able to be seen or observed. Now if you get too close to one, you may die. So black holes are still a mystery to be solved. Black Holes are massive in weight and they get bigger the more matter they suck up/ absorb. Black Holes are like the sibling(s) to wormholes. Blac...
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, and if it has collapsed under its own weight, it will have formed a star. This core is said to have nearly zero volume, but with infinite density, known as a singularity.
Black Holes The term black hole was first used in 1969 by the American scientist
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 black holes in detail, by thinking about gravity under fairly simple circumstances.
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.
