Understanding Black Holes

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

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

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.

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

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

Another thing that makes a black hole a black is the size. The size of black holes depend on the mass size. From smallest to largest size, Primordial being the smallest being almost as tiny as a single atom. Stellar is the middle sized black hole, abling the mass to be up to twenty times larger than the mass of the sun. Super massive the largest form of a black hole have masses which are able to be greater than one million suns joined together (Dunbar,

Black holes have been theorized since 1916. However, no scientist has ever discovered a black hole in certainty. In theory, A black hole is created when a star of three or more solar masses collapses. “One solar mass is equal to the mass of the sun,” (Mclintock 1). A star collapses when the outward push of the combustion reaction no longer has the required forces compete with the inward pull of gravity. Most astronomers believe that the Milky Way contains millions of theses invisible devils, which are massive stars that have collapsed. In theory, anything could become a black hole if it were simply compressed into its Schwarzschild radius. For instance, Mount Everest has a Schwarzschild radius that is less than a nanometer,

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

Throughout the lifespan of galaxies and universes, interstellar objects are created and destroyed including stars, asteroids, nebulas, and black holes. One of the rarest interstellar creations are black holes, of which are only found in three forms. These three forms include stellar, supermassive, and intermediate black holes. Black holes are mysteries that were not fully understood until the beginning of the 20th century, when multiple scientist focused their research on them. They predicted theories and made many discoveries. These scientists include Sir Isaac Newton, Albert Einstein, John Wheeler, and Stephen Hawking. These scientists have helped us to quickly advance our knowledge on the universe and surrounding galaxies.

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

Supermassive Black Holes: These types are the biggest among the three. They are created at the same time as the galaxy they are in. The size of the supermassive black hole is related

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

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

Black holes are the mystery of our cosmological universe. They have been baffling even the greatest scientists like Stephen Hawking for many years and yet not many people know about them. To understand how black holes are confusing scientists and how they can affect us, have to know how black holes work. Black holes are created whenever a giant star, twenty-five time bigger than our sun, dies and collapses from its own gravity to form an object of infinite density which forms a black hole. If you were to analyze the parts of a black hole, you would find an event horizon and the singularity. The event horizon is basically the point of no return, which means that nothing can escape the black holes grasp once it reaches that point, not even light. Then after that is the singularity which is the point of infinite density.
