How Do Miniature Black Holes Affect The Evolution Of The Universe?

Albert Einstein first predicted black holes in 1916 with his general theory of relativity. The term "black hole" was coined in 1967 by American astronomer John Wheeler, and the first one was discovered in 1971. A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars. Scientists think the smallest black holes formed when the universe

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

(2) Sub-stellar objects with true masses above the limiting mass for thermonuclear fusion of deuterium are brown dwarfs, no matter how they formed nor where they are

Although the basic formation process is understood, one perennial mystery in the science of black holes is that they appear to exist on two radically different size scales. On the one end, there are the countless black holes that are the remnants of massive stars. Peppered throughout the Universe, these "stellar mass" black holes are generally 10 to 24 times as massive as the Sun. Astronomers spot them when another star draws near enough for some of the matter surrounding it to be snared by the black hole 's gravity, churning out x-rays in the process. Most stellar black holes, however, lead isolated lives and are impossible to detect. Judging from the number of stars large enough to produce such black holes, however, scientists estimate that there are as many as ten million to a billion such black holes in the Milky

A supermassive black hole is somewhat an extreme form of a black hole; however, they are more common than one would think. Supermassive black holes sit at the center of every galaxy, including our own. They are what keeps the stars and solar systems in the orbital of the galaxy. The two seeding theories (big and small) are a reasonable, current way to describe the formation of these extreme beings. The small seeding theory summarizes that the black hole slowly eats smaller black holes to enlarge its size, this theory is valid but violates certain placed laws in physics that are more than likely, not to be broken. The larger seeding theory states that the density of dark matter at the beginning of the universe attracted large gas clouds and cut off the formation of smaller stars. This gas cloud then collapsed to form and extremely large star, that then collapsed once more to for a black hole that attracted more gas and other particles. This theory is believed amongst astrophysicists but it is also denied by some, saying that the dark matter has nothing to do with the massive star formation, and that a black hole can form by an average star collapsing and gaining excessive

To begin, one type is a stellar black hole (“hubblesite” 1). Stellar black holes come from the collapsing of a massive star. Another kind of black hole is a supermassive black hole that has the mass of one billion Suns. Next, there are intermediate black holes, which are mid-sized (“science.nasa” 1). Astronomers have a theory that miniature black holes may exist and are smaller than our Sun (“hubblesite” 1). It is unknown if the theory is true or not. Finally, scientists have discovered some black holes spin while others stay stationary. A spinning black hole rotates around its axis while a stationary black hole do not spin at all. As astronomers have studied the differences of black holes, they have gained additional

First the mystery of the black holes and how they were created goes way back to when astronomers first discovered them. The astronaut said “he saw a blob of black matter and black holes are made when a star burns out or explodes but the astronaut never truly saw the actual thing. Black holes absorb light particles that are close enough to it so that it can thrive and continue. When a black hole goes away the light that it absorbed is turned into a new star. When an astronomer found a black sphere shaped cloud of matter in space he didn't really see it but he saw it pulling in large amounts of light that have been destroyed from an exploded star. If anything but light matter happens to get into a black hole it would just go through it rather

Next, is the stellar black hole, this is the one that which was mentioned earlier. It is formed when a star runs out of core energy. Stellar black holes are said to slowly shrink away. Last is the supermassive, which are the size of billions of suns. These black holes are said to be at the center of galaxies. Scientists say that the center of our galaxy is a black hole.

There are three main types of black holes primordial, stellar, as well as supermassive. Primordial black holes are smallest of the three. This means they can’t suck in as big of objects as the other two. These are

The formation of this star is determined with the size of the stellar core. For example, the black hole formed if the stellar core is larger as compared to the solar masses leading to a complete collapse of the stellar core. Black hole is dense object with strong gravity

Scientists aren't certain of how supermassive black holes are created. It could be because hundreds or thousands of tiny black holes merge together, large gas clouds could also be responsible, collapsing together. A third option is a group of stars all collapsing together. Once supermassive black holes have formed, they gather dust and gas from around them, causing them to grow even bigger.

There are at least two different size ranges for black holes. The first are those of stellar mass, about 10 to 24 times as massive as our sun (“Black Holes”). The second are supermassive black holes (“Black Holes”). Supermassive black holes can contain millions to billions of times the mass of our sun (“Black Holes”). They can grow to such enormous sizes because of the considerable amounts of matter in the center of galaxies, where supermassive black holes are found (“Black Hole Images, Facts and Information”). For

Precisely, an object falling into a black hole appears to slow down as it draws nearer to the event horizon but never really reaches it, due to the gravitational time dilation effect (Nrumiano, n.d). Similarly, an outside observer will experience all processes on an object nearing the event horizon as slowed down, and the emitted light will appear dimmer and redder due to the gravitational red-shift effect; as soon as the falling object reaches the event horizon, it becomes so dim that it can never be seen. Black holes often form at the ends of the lives of massive stars as these stars often collapse at the end of their life cycle, when all the sources of nuclear fusion in a star are exhausted (Kaaret & Ford, 1997). After forming, black holes have the capacity of increasing in size by swallowing up mass from their environments such as nearby stars and fusing with other black holes thereby creating super massive black holes whose mass exceeds several million solar masses (Alexander, Smail, Bauer, Chapman, et al., 2005). Astronomers have reached a general consensus that nearly all galaxies have super massive black holes at their centres (Cattaneo,

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.
