What would happen if a star or even our sun exploded? This question was asked for many years while scientists studied to try and figure out the answer. The solution is a simple concept called a black hole. Black holes form during explosions of massive things such as stars. The gravitational pull in black holes is so strong that nothing can escape it, including light. This causes them to be slightly invisible, but modern scientific technology can detect them. There are three other different kinds of black holes: Stellar, Primordial, and Supermassive. These types are separated based on when and how they formed. The next question is, how do they form? Primordial black holes are believed to have formed close after the creation of the universe …show more content…
These black holes are the second largest type and form during the explosion of a massive star. Some types of large stars can have their center collapse in upon itself. This causes an explosion that blows particles of the star among the universe. The star’s mass pushes together so vigorously, that it explodes and causes a black hole to form. Massive stars burn their fuel over billions of years but the fuel does not last forever. When these stars finally run out of fuel, the core is completely burned and all that is left is iron. This causes the star to begin to collapse which then turns into a massive explosion. Stellar black holes are the most common type of black hole out of the three different …show more content…
When a black hole and a star are orbiting near each other, a certain kind of high energy light is produced that allows scientists to distinguish where they are. This technology has allowed us to learn many new things such as why sometimes objects in space don’t get sucked into black holes. Scientists observe gamma ray waves as well. With this technology, we have discovered that our sun would not be able to become a black hole because it is too small. Instead, it would turn into a giant red star when it runs out of fuel. Although, if our sun did have enough mass to become a black hole, it would not affect the way Earth orbits the sun. Since the black hole would have the same mass as our sun, the planets in our solar system would still orbit the black hole just the same and would not be pulled into the black
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. (Swinburne University 2014). It is believed that a normal black holes were formed because of a supernova explosion of a gigantic star, meaning when huge stars collapse, so the larger the star, the larger the black hole. ( Millis 2014) . So therefore a simple idea of how a super massive black hole might have been formed would be because of a collision of super enormous star or a collision of star clusters (star clouds). (Super massive black holes 2014)
When itBetelgeuse cannot fuse anymore anything over iron, the star will not have enough energy to make heat. Eventually, the core will collapse. When Betelgeuse collapses, it is so strong and powerful that it causes the outer layers to rebound. With the rebound it will have an explosion, which is called a Supernova (Type two). The explosion has so much energy and power that the temperature becomes really hot. The temperature is so hot that it can use the fusion process much heavier than iron. The elements that were given off from the explosion are sent throughout space and are now new nebula. When the Supernova is done, it has left behind a star called a Neutron star. They form when atoms of the core of a dead star are crushed together and the end result produces neutrons. The neutrons are with electrons that are degenerate on the surface. Many Neutron stars have magnetic fields and they give off strong waves of radiation from their poles. These types of Neutron Stars are known as Pulsars.
Geologist John Mitchell is credited with first devising the idea of a black hole. He said that if some force could compress the sun down to an small enough size, it would have a gravitational field so strong, that one would need to be going faster than the speed of light to escape it (UTFC). All objects in the universe have what is called a schwarzschild radius. An object’s schwarzschild radius is the radius that an object would have to be compressed into in order to have an escape velocity greater than that of the speed of light, or a black hole. (VSBH).
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:
...f gas, which collapsed and broke up into individual stars. The stars are packed together most tightly in the center, or nucleus. Scientists believe it is possible that at the very center there was too much matter to form an ordinary star, or that the stars which did form were so close to each other that they coalesced to form a black hole. It is argued that really massive black holes, equivalent to a hundred million stars like the Sun, could exist at the center of some galaxies
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, and will inform you the reader of the most popular and widely accepted theories surrounding them.
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...
A Black hole is a theorized celestial body whose surface gravity is so strong that
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.
Just recently a major discovery was found with the help of a device known as The Hubble Telescope. This telescope has just recently found what many astronomers believe to be a black hole, After being focuses on a star orbiting empty space. Several pictures of various radiation fluctuations and other diverse types of readings that could be read from that area which the black hole is suspected to be in.
Stars are born in the interstellar clouds of gas and dust called nebulae that are primarily found in the spiral arms of galaxies. These clouds are composed mainly of hydrogen gas but also contain carbon, oxygen and various other elements, but we will see that the carbon and oxygen play a crucial role in star formation so they get special mention. A nebula by itself is not enough to form a star however, and it requires the assistance of some outside force. A close passing star or a shock wave from a supernova or some other event can have just the needed effect. It is the same idea as having a number of marbles on a trampoline and then rolling a larger ball through the middle of them or around the edges. The marbles will conglomerate around the path of the ball, and as more marbles clump together, still more will be attracted. This is essentially what happens during the formation of a star (Stellar Birth, 2004).
Supernovas are extremely powerful explosions of radiation. A supernova can give off as much energy as a Sun can within its whole life. A star will release most of its material when it undergoes this type of explosion. The explosion of a supernova can also help in creating new stars.
Hundreds of suns explode every year in our Galaxy, at any moment entire planets of beings would be reduced to nothing whether good or
Initially, Albert Einstein was the person to predict the existence of black holes through his General Theory of Relativity, in which he had created several general equations that show the interaction of gravitation as a result of space being curved by matter or energy. In 1915, he published Einstein’s field equations, which specify how the geometry of space and time is influenced by whatever matter and radiation are present, and form the core of Einstein's general theory of relativity (Redd). The general theory relativity was the initial step in the process to finding out more information about black holes. As time went on, there were a few main contributors that solved these equations to help develop better theories on black holes. One of the most important contributors to the development of a better u...
Black holes were first theorized by Albert Einstein in 1916 with his general theory of relativity. With his general theory of relativity Einstein proposed that gravity isn’t just a force as Sir Iscaac Newton had formally stated. Instead gravity is a consequence of a distortion in space and time. These distortions vary but the more mass an object processes the more of a distortion they have on the fabric of space-time causing the other objects to be drawn in due to the distortion. For example the planets in our Solar system aren’t simply being pulled in by the sun but they are instead revolving around the warped space-time
