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.
When a bigger star falls in on itself it keeps going to make a stellar black hole (“Black Holes: Facts”). The biggest black hole also known as the supermassive black hole is believed to be in the center of every galaxy even in the Milky Way (“Black Holes: Facts”). Also supermassive black holes are millions to billions of time... ... middle of paper ... ...e of the Schwarzchild black hole is the Kerr black hole which rotates instead of just standing still ("Black Holes." Black). The Kerr black holes rotation happens when the black hole was created ("Black Holes."
A black hole is an object so compact that, close to it, even the speed of light is not fast enough to escape. A common type of black hole is the type produced by some dying stars. A star with a mass greater than 20 times the mass of our Sun may produce a black hole at the end of its life. In the normal life of a star there is a constant tug of war between gravity pulling in and pressure pushing out. Nuclear reactions in the core of the star produce enough energy to push out.
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... ... middle of paper ... ...is its anti particle. When these particles appear, they will shortly annihilate each other because they are exact opposites (UCR). However, if one of these particle pairs appears at the event horizon of a black hole, the gravity from the black hole will tear the pair of particles apart. The normal particle will have just enough energy to escape the black hole.
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 environment on a neutron star is incomprehensibly brutal. Neutron stars are the leftovers of stars with a mass of four to eight times that of our own sun. A neutron star can be formed when the star goes supernova. A star goes super nova when the star runs out of hydrogen to fuse into helium. When all of the hydrogen is used up, the star starts to fuse helium, and it keeps fusing heavier and heavier elements, until it reaches iron.
In conclusion, quasars and pulsars are beautiful, powerful, and slightly terrifying, celestial formations. Quasars are black holes consuming super dense star dust and emitting faint radio signals. Pulsars are the remnants of once great stars that have lost all of their neutrons. They spin at an extremely fast rate and release high intensity beams that “pulse” in and out of view. They are both fantastic and interesting phenomenons of the universe.
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 no longer produce the expansive force, a result of normal gas pressure, that supports the star against the compressive force of its own gravitation. As the star shrinks in size (and increases in density), it may assume one of several forms depending upon its mass. A less massive star may become a white dwarf, while a more massive one would become a supernova.
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.
Super-massive black holes having a large mass would make its gravity incredibly limitless, this would mean that even a star which is many light years away would be impelled by the super-massive black hole. (Millis 2014) The responsibility of super massive black holes is to hold the galaxies together. (Millis 2014) Super massive black holes are very dense and its believed that their density can reach infinity in a way that even light can't pass through their gravitational force. (NRAO 2014) 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) It is believed that super massive black holes exist in the cores of many large galaxies, including the Milky Way galaxy, which is our galaxy.
