Black Holes : A Black Hole

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

Throughout the modern era of astronomy, a single type of celestial object has puzzled astronomers more than any other. Black holes, whose existence was only verified in the early 1990’s, have fascinated scientists ever since Einstein first proposed the theoretical concept in the 1930’s. A black hole is an object so tiny, but also so dense, that it has the power to pull planets, stars, and even light into its core, and ultimately destroy everything in its path. Over the past decade much has been discovered about these enigmas of space and time; however, many of these recent discoveries lead to more unanswered questions. Nevertheless, the basic life cycle of a black hole is now understood in ways thought to be impossible only twenty years

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.

A black hole is a region in space where the pulling force of gravity that is so strong that the region cannot escape. This compression can take place at the end of its stars life. Some black holes are a result of dying stars. How every space telescopes with special instruments can help find black holes. They can observe the behavior of material and stars that are very close to black holes. Black holes can come in a rage of signs, but there are three main types of black holes. The black holes mass and size determins what kind it is. The smallest ones are known as primordial black holes. Scientists believe this type of black hole can be up to 20 times greater than the mass of the sun and fit into a ball of about 10 miles. The largest black holes are called supermassive. Supermassive black holes are at the center of the milky way galaxy is called sagittarius. A black holes gravity can be as strong to pull off the outer layer gass of the star and grow a disk. The

The common conceptual intuition of black holes includes the fact that they attract matter with great force in such a manner that it engulfs everything in its proximity. The concept of accretion disks and as we shall see, particles escaping the gravitational potential,

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

Black holes come in various sizes ranging from the size of an atom to black holes with 5 million times the mass of the sun. Black holes are usually small but they have

Miniature Black Holes: It is said that this type was formed during the Big Bang, but there was no evidence to prove this within the evolution of the universe. The mass of these black holes is much smaller than the mass of the sun, and they have formed through the external pressure during the Big Bang that compressed the mass to create the singularity. (Mathew,2012)

A little more in depth: Black holes are the remnant of stars that have gone supernova and collapsed upon themselves. When the star explodes in a supernova, not only does it explode outwards but it pushes inwards on its own core as well. The pressure placed on the core causes it to implode upon itself, and that's where the black hole is formed. However, black holes are only formed by stars large enough to create one... for instance the sun, everyone's favorite star, will likely not become a black hole once it goes nova. A star 10 times the size of our sun probably will, depending on how much matter is lost in the supernova. Only those huge stars have enough gravity to create a black hole.

Mysteries of black holes always unknown as in where they come from. “Black holes form when the center of a massive star collapses in on itself.” When this occurs, it causes a supernova. A supernova is a star that increases greatly in brightness because of a catastrophic explosion that ejects most of its mass. The parts left over from the supernova collapse in onto itself forming a black hole. This well-known black hole is called a stellar mass black hole. “Scientists believe supermassive black holes have formed at

As more material is pulled into a black hole, it grows bigger and its gravity strengthens (Sipiera 29). Also, a black hole’s gravitational pull is so strong that light can even be pulled into the hole (Jefferis 4). Next, black holes are the last step of the life of a star. Although a black hole’s gravity is strong, only a small part of space will be swallowed. Because black holes are able to pull light into themselves, they cannot be seen. These are a few of the facts that scientists have uncovered.

A quasar is defined as a massive celestial object, producing large amounts of energy and light. These are believed to contain massive black holes in their centers. These large celestial objects were thought to be abundant at the early beginning of the universe, but now have slowly turned dormant (Shields and Kormendy).There are multiple kinds of black holes that exist in our universe, one of them is a quasar as previously stated. These black holes exist in a massive ball of gasses and dust that is used as fuel for the black hole. These objects can be thousands of times brighter that even the brightest star found due to the extreme amount of energy released (Mari 56). They are often found at the centers of galaxies and are credited towards the early formation of the universe. They then run out of fuel and continue to be the strong gravitational force at the center of most galaxies holding them together (Shields and

When many people think of black holes they think of a giant portal in space eating galaxies and moving on to the next as most commonly seen in pop culture shows such as Star Trek. The reality is however that while we spend a lot of time studying them we know very little about Black holes. What we do know is that there are two types of black holes based on their relative size, there are Stellar black holes and Supermassive black holes. Stellar black holes are only a few times larger than our sun while Supermassive black holes are about a billion times larger than our sun. Both types of black hole are formed when a star implodes and there is nothing left to burn. This can be seen by observing how light and matter cooperate with the event horizon, a second way to detect black holes is through X-Rays by noticing when stars rotate around a gap in space. By studying the speed of stars orbiting, and calculating their paths it is possible to determine the mass and size of a black hole. Using these pieces of evidence we can determine that stellar black holes do exist and

Black Holes are the universe's most mysterious objects known to mankind. It lies in the darkness waiting and waiting for something...anything to come up and devour it without a trace. Black Holes are relatively new to humans, but we know that they’ve been here for millions and millions of years. Many people are unaware of the history of black holes, how a black hole is created and its function , and how there were theories leading up to black holes.

Another method in physics on how to time travel is through black holes. A black hole has been discovered by Einstein's theory of general relativity, which showed that when a star dies, it leaves behind a small, dense remnant core. If the core’s mass is more than the sun, the force of gravity overwhelms all other forces in which it transforms into a black hole. Scientists have said that black holes can destroy anything that goes in it and it could be hard to get out of a black hole, once something went in it. In an interview by physicist Lior Burko, he states, “One possibility is that black holes may allow us to travel to very remote places in the universe, or another universe entirely,” (Kahney, “Black Holes and Space Time”). Black holes may have evidence that there are different kinds of parallel universe. Even though it is still unclear what black holes can do as in destroying everything that it goes in or if it leads someone to time travel into another parallel universe. Scientist are trying to create a black hole, here on earth, to see what blacks can do as in sending information to another universe.
