One of the most interesting things that can happen in space is a black hole. A black hole can almost be described as a vacuum. It is a spot in space where gravity is constantly pulling materials into it. The gravity is so strong that light is not even able to escape from the black hole. The reason why the gravity of a black hole is so strong is because all of its matter has been squeezed into a tiny space. This happens when a star starts to die. People cannot see black holes because light cannot escape. Black holes are invisible in space. Astronomers have developed space telescopes with special tools that can help locate black holes in space. These tools are able to see how stars that are very close to black holes react differently than stars …show more content…
Black holes form from the remnants of a very massive star that dies in a supernova explosion. Smaller solar mass stars will become dense neutron stars when they die. These stars do not have enough mass to trap light. If the total mass is about three times the mass of the sun, it is proven that no force will keep the star from collapsing under the influence of gravity. While the star is collapsing, a strange thing begins to occur. While the surface of the star nears the event horizon, the time on the star begins to slow relative to the time kept by observers from far away. When the surface of the star reaches the event horizon, time begins to stand still and the star cannot collapse any more. The star is now a frozen collapsing …show more content…
Our Sun is not large enough to become a black hole when it dies. When the Sun loses all of its available nuclear fuel in its core, the Sun will die a quiet death. Stars that have the same size as the Sun are called Solar Mass Stars. When a Solar Mass star dies, its remnants become a white dwarf. Stars that have more mass will eventually become a black hole when they die. When a massive star loses all of its fuel, it is not able to sustain its own weight anymore and begins to collapse on itself. The massive star begins to heat up and a fraction of the stars outer layer. The massive stars outer layer also contains fresh nuclear fuel. This activates the nuclear reaction again and an explosion called a super nova happens. The innermost part of the massive star, the core, still continues to collapse. Depending on the size of the stars core, the star might become a neutron star and the collapsing stops or it will keep on continuing to collapse into a black hole. The dividing mass of the stars core is what determines the stars
On the other end of the spectrum, the death of a super-massive star is one of the most brilliant displays of pure power in the universe which includes an amazing light show which has no equal. A super-massive star is exactly what it sounds like, a star so big that it dwarfs our own star in every way. When a super-massive sun begins to run out of out of hydrogen it begins to collapse, but due to its immense gravity and size, the collapse produces such an abrupt implosion that the last remnants of nuclear fusion remaining push all the mass of the star back out into space (Britt, 2007). This can be compared to someone jumping onto a trampoline whose elastic has enough elasticity to force one back into the air. This occurrence is known as a supernova explosion, which is the largest explosion in the known universe. A supernova explosion can even be seen from other galaxies, as scientists have done witnessed from observations using the Hubble telescope. The star is so big, however, that it only blows its outer atmosphere away, still leaving a massive amount of matter that is doomed to collapse again, and this time it will be a one-way ticket to oblivion. The super-massive star finally collapses and its own incredible mass crushes it’s internally and now turns it into a neutron star. An average neutron star is about ten miles in diameter, or the size of Manhattan. Although this
Many philosophers have said that the ‘Eyes are the windows to the soul.’ The eyes can show a person’s true personality. Not their clothes, facial expressions, or how they hold themselves, but looking into another’s eyes will show one’s soul. But what if their personality was not found in their eyes, but on their body in the form of a mutation? As found in Black Hole, the town’s teens have contracted an STD they call “the bug.” Each teen that acquires it grows an external mutation. This can especially be seen with some of the main characters: Keith, Rob, and Chris. Keith grows appendages that look like tadpoles on his chest. Rob has another mouth on his neck. Chris sheds her skin. Each of these mutations indicate what this person is actually like. The external mutations of Keith, Rob, and Chris symbolize the characters’ inner selves.
A black hole is a point in space where there is extreme gravitational pull, so extreme that light itself cannot escape. The strength of gravity is so strong due to the fact that an immense amount of matter has been contained in a small space.
Due to the strong gravity pulls, all of the light around a black hole is sucked into the middle. Scientists can see how the strong gravity affects the stars and gas around the black hole however, study to see if the stars are orbiting the black hole. (Space) This is how they know they exist, by studying the stars around them. Also, when a black hole and a star are close together, a high energy light is formed, which humans are incapable of seeing. However, satellites and telescopes can see these high energy lights, allowing us to spot black holes
Black holes are some of unusual and most interesting objects found in outer space. The first thing I learned, black holes are objects of the greatest density due to the strong gravity because mater has been squeezed into a tiny space. With the black holes relationships with mass and gravity, they have an extremely powerful gravitational force that even light cannot escape from their grasp if it comes near enough. Second thing I learned is about the inner region of a black hole, where its mass lies, is known as its singularity, the single pint in space-time where the mass of the black hole is concentrated. The third thing I learned that I found the most fascinating is if the earth ever falls into a black hole, one of the effect that will happen is “spaghettification,” which means if objects come too close to a black hole, it will stretch out, just like a spaghetti. This effect is brought about by a gravitational gradient across the object or a body. For example, if earth comes too close to a black hole, the nearest part of the planet will be pulled by an enormous gravitational pull, while leaving the farthest part with a small gravitational force. The fourth thing I learned is that the new hypothesis suggests that anything that touches a black hole will become an
Type II supernovaes, which are more common, occurs when a star runs out of nuclear fuel and collapses under its own gravity. In a Type II supernovae, once the star’s core surpasses a certain mass (The Chandrasekhar limit) the star begins to impolode. The core then heats up and becomes denser. Eventually the implosion bounces back off the core, expelling the stellar material into space. What’s left is a neutron star.
A blackhole occurs when a giant or supergiant start dies. But before the star dies their is a fusion reaction going on constantly throughout its life time. This fusion reaction can be di erent from star to star ff depending on its age. For a young star the reaction is a proton to proton fusion, a middle aged star can have a carbon reaction and a much older star, which is collapsing on itself has a helium fusion reaction. Once a star has finished reacting all of the helium it has the core begins to 'eat' it's self instead of the helium. This makes the core have a stronger and stronger gravitational pull. After the core has 'eaten or suck up everything into its fusion reaction it collapses due to so much compressed mass in a small space which forms a giant explosion creating a supernova which then turns into a singularity. Thus
Nothing can escape a black hole, even light it self. If two large amounts of gravity came to close to each other, they would distorted each other. There are two galaxies orbiting each other and one is stealing the stars from the other. The two galaxies pull at each other even if you can see it in motion. Stars in the galaxys get pulled apart and anything in the galaxy is most likely
They are scattered throughout the galaxies. A stellar black hole is the product of the death of a giant star such as a pulsar or a neutron star. Black holes in general are very rare because most stars are not massive enough to create them. When a star stops producing fusion energy, the equilibrium of the star no longer exists. Without the star producing any fuel, there is no pressure created that can hold the star in place. The pressure that a star creates is used to prevent the gravity from crushing the core. Now that there is no pressure pushing outward, the gravity becomes so violent that it crushes matter to the point that it is completely destroyed. At this point, black holes are born. Black holes are created in rare occasions. During the death of most stars, they slowly dim out or explode into trillions of microscopic particles. For example, the sun, which is a red dwarf, will slowly die out. Eta Carinae on the other hand, located 8,000 light years away from Earth, is likely to explode within the next several hundred thousand
Common types of black holes are produced by certain dying stars. A star with a mass greater than 20 times the mass of our sun can produce a black hole at the end of its life. Black holes are usually only created by the death of a very massive star. When a very massive star dies, it explodes into a supernova. The outer parts of the star are launched violently into space while the core completely collapses under its own weight. If the core remaining after the giant explosion from the supernova is very massive, there
“Dark Stars,” are dense enough to prevent light from escaping into space. “Dark Stars” are known and Black Holes and Black Holes were believe for it to capture light there must be a density high enough to be capable, but since no one has survived and measured the density of a black hole we believe that in that center it has an infinite density. http://physicsforidiots.com/space/black-holes/ The idea on how Black Holes are studied by the mass of the dying star. Density can draw out light if it were strong enough to cover the mass. This supports the claim if a Black Hole would engulf the mass of a sun no trace of
Black holes are formed when massive stars collapse under the weight of their own gravity (Schoolworkhelper Editorial Team). The nuclear fusion in younger stars creates a constant outward pressure from the core (“Black Hole Images, Facts and Information”). This balances the pull from the gasses in orbit around the core, keeping the star stable (Schoolworkhelper Editorial Team). Once a star’s life is nearing the end, and its gasses have almost all been used up in the nuclear reactions, the star will collapse inward from the gravitational pull without the outward push of the reactions (Schoolworkhelper Editorial Team). This happens to stars of at least six to eight times the mass of our sun (Schoolworkhelper Editorial
Black Holes are formed when massive stars, about 20 times the mass of our sun run out of fuel and nuclear fusion cannot take place. The gravity cause the star to collapse into itself and explode releasing a lot of gas and particles out into space. When stars explode this way, it’s called a supernova. In younger stars the nuclear fusion opposes the force of gravity which keeps the star stable. However now that there isn't any force to oppose the gravity, it keeps collapsing inwards until eventually all the mass gets concentrated to a single point. This single point is called
When the star actually starts to run out of nuclear fuel some of the mass flows into the star's core. When the core becomes too heavy it cannot take its own gravitational force. Which causes the core to collapse, and as it collapses it results in a giant supernova. Many people worry that the sun will become into a supernova. That has no chance of happening because the sun does not have enough mass to become a supernova.
Main sequence stars like our own sun enduring in a state of nuclear fusion during which they will produce energy for billions of years by replacing hydrogen to helium. Stars change over billions of years. When their main sequence phase ends they pass through other states of existence according to their size and other characteristics. The larger a star's mass, the shorter its lifespan is. As stars move toward the end of their lives, much of their hydrogen will be converted to helium. Helium sinks to the star's core and raises the star's temperature—causing its outer shell to expand. These large, puffy stars are known as Red Giants. The red giant phase is actually a prelude to a star shedding its outer layers and becoming a small, dense body called a White Dwarf. White dwarfs cool down for billions and billions of years, until they finally go dark and produce no energy at all. Once this happens, scientists have yet to observe, such stars become known as Black Dwarfs. A few stars avoid this evolutionary path and instead go out with a bang, exploding as Supernovae. These violent explosions leave behind a small core that will then turn into something called a Neutron Star or even, if the remainder is large enough, it is then turned into something called a Black Hole.
