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.
Black holes are born by using many of the star's energy so it can evolve.Black holes you can rarely find them in space they are, so common in space that they are hard to find and since space is really dark than black holes are going to be even harder to find. The way black holes form is by them beginning of as a star and then using all the other stars energy to start evolving and growing bigger. And the cycle is pretty complicated because it will take days to gather enough energy from all the other stars it may even take years for the black hole too become an adult. When the black hole takes up all the energy from the star the star breaks up into a million pieces maybe chances of creating another star. Black holes are mostly stars but bigger and filled with energy from millions of
Furthermore existence that black holes exist comes from the observations of astronomers of bursts of energy which are detected and then lost. An event horizon is an area of space around a black hole for which nothing can escape, once an object or any matter crosses this event horizon the gravity of the black hole will be too strong for it to escape. As a cloud of gas swirls and nears a black hole, the gases heat up and will emit x-rays. Astronomers have observed instances of several burts of x-rays being detected and then disappearing at areas where black holes are thought to be found. This may be caused by the gases emitting x-rays and then crossing the event horizon and disappearing forever. The observations of these bursts of energy are useful for astronomers in finding black holes.
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
Black holes are created when a star's very heavy core is squeezed hard enough to create matter into a tiny spot smaller than a pinhole from which nothing can escape including light. (Darling D., 1985).
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
Black holes are in theory incredible frightening. One of the main reasons they are so monstrous is that they are one of the only thing in the universe able to trap light. The second reason they are so terrifying is that when you are being pulled into one you will be on a one way ticket train to emptiness. Therefor if there was a way to get out of a black hole what would it be? Then also if there was no way out what would it look like on the inside? Well some of these questions can be answered easily but for the others it will be a little more troublesome to answer. This is how, what, and why black holes are formed.
This paper will introduce you to the incredible topic which is black holes. A black hole is a region of space time exhibiting such strong gravitational effects that nothing can escape from inside it. (NASA) No human has ever entered a black hole and there is still a large mystery about them; we have very little idea of where the matter that enters them goes. A black hole cannot be looked into either, as it sucks all the light into the middle of it. Space programs use special satellites with certain features that allow them to see these black holes. A black hole can be big or small, sometimes forming when a star is dying. Some scientists speculate that there can be black holes just 1 centimeter large. There are multiple types of
Discovered in 1916 by Albert Einstein, a black hole is an area of space-time showing very strong effects, that nothing can escape from the black hole. Space-time is the belief that there is no time in space, so there is no aging or time whatsoever. There are three different types of black holes. Stellar-mass, supermassive, and intermediate. All three are very strong, but the supermassive is currently the strongest reported. Not all black holes are large, but extremely powerful. The supermassive black holes are the biggest type of black hole and most of the time are found in the center of massive galaxies. Stellar-mass black holes are formed by a star collapsing. Intermediate black holes are stronger than stellar-mass black holes, but weaker than supermassive. Supermassive is the least common black hole there is.
Due to this a lot of matter condenses to a small space which causes gravity to be stronger that not even light can escape. And since there is no light we ca not see it due to it being so dark rendering it virtually invisible, luckily we have created space telescopes with special tools to help us locate Black Holes. As we all know the strength of the gravity of the Black Hole varies on its size, but what we don't know is that where does everything a black hole pulls into it go? For as long as we have know about Black Holes we have wondered, where do the things a black hole takes go? Many scientist have theorized a numerous amounts of possibilities. And as of know we will never know and hopefully we
They have no specified mass or size. To this date astronomers have only found evidence of black holes in two circumstances. However the gravitational pull of the black hole is so strong that nothing can escape from it, not even light. This image shows a star being sucked in by the black hole. Black holes are so dense that the density cannot be measured, they also disfigure the around it, and often sucks matter into them including star no matter how big they are. By definition black holes do not give any light but when the black hole pulls the star towards itself and tears it apart, the matter of the star it goes to the black hole, the matter gets faster and hotter and glows. Black holes are weird and if you get too close to them they are dangerous. Suppose one person is falling into a black hole while another person watches him fall. The closer the person comes to the black hole the slower his time will run as for the person watching the other person fall into the black hole his tome will run at a normal pace but the time for the person falling into the black hole will become slower. However, black holes do have a life and do not live forever, as the black hole radiates energy it shrink, it radiates more and shrinks, and finally it reaches at a point where it completely
The stars are born from gas and dust. Even the sun formed this way. Stars are also classified by color, temp., luminosity, and distance from the earth. Stars form inside a cloud of dust called a Nebula. Gravity pulls gas and dust closer together in some place of the Nebula. When the matter contracts, it forms a hot sphere. Did you know the color of the star is the effect of the temperature of the star. The sphere then becomes a star if the center grows hot and dense enough for fusion to happen. As you can see stars, like the sun, are born out of gas and dust that gets contracted.The different stages a star goes through depends on the mass of the star. Lower-mass stars develop
The theory of cosmological natural selection implies that black holes are essentially the gateways to newly created universes. The concept of quantum gravity is not well understood yet, but it has been theorized that strange effects happen as matter approaches the singularity of a black hole. Some have speculated that matter may actually expand instead of collapse in the center of a black hole. Black holes are the starting point for an expanding region of spacetime from that point. This effect is called “bouncing.” The powerful effects created from the black hole allow matter to bounce through the singularity and begin to form a new universe. When a star collapses to form a black hole, the matter that is inside the horizon eventually “bounces out of the universe” as it reaches the singularity.
Indecent bodies like the sun. Stars are made up of big exploding balls of gas, mostly hydrogen and helium. The sun is similarly a star made up of huge amounts of hydrogen, undergoing a continuous nuclear reaction like a hydrogen bomb. Stars come about when vast clouds of hydrogen, helium and dust contract and collapse due to gravity. The clouds came from astronomical plasma from “The Big Bang”, but the dust comes from the supernovae of other stars.
