Black Holes Research Papers
Black holes are a very interesting and fun topic to learn about! A black hole is a hole in space that sucks things in, not even light can get out. These holes pull forcely because stronge matter has been squeezed into a tiny space. Light can’t get out, so the human eye can not see them. Scientists use special equipment for seeing black holes. The tools can see how stars around the black hole act differently than the stars away from the black hole. Black holes were first discovered in 1916 by Karl Schwarzschild. Scientist can not see the black hole because of the strong gravitational pull that takes all the light from the area. They were discovered by how they change stars’(that are around them) orbits.When the black hole and the star are close together, it creates a high-energy light that can not be seen by the human eye. The black holes can pull hard; nothing has ever gotten out out of one!

Well, black holes can be big or small. Scientists believe that the smallest black holes are as small as just one atom. These tiny things might be small, but they have a mass of a large mountain! Mass is the amount of matter in an object. There are other kinds of black holes, too! There are bigger black holes that are called “stellar” black holes. Stellar black holes can have a mass 20 times more than the sun! There are many stellar black holes in Earth’s galaxy. Earth’s galaxy is called the Milky Way, but it’s not a candy bar! Stellar black holes aren’t the biggest, though! There are bigger black holes called “supermassive” black holes. These kinds of black holes have the mass of OVER A MILLION SUNS TOGETHER!!!WOW!That’s a lot of mass! Scientists have discovered proof that every galaxy has a supermassive black hole in the center! The supermassive black hole found in the center of the Milky Way was named Sagittarius A, and do you believe me when I say that Sagittarius A has the mass of about 4 MILLION

    Hershel and Ritter

    Herschel discovered infrared light when he was observing the sun he noticed that when he put coloured filters over his telescope that different coloured filters heated up his telescope by different amounts. Using a prism he broke up visible light he put a thermometer in the different colours. He found that the temperature got more massive as he moved the thermometer from violet to red after this He then measured the temperature where there was no visible light ( red end of the spectrum) and it was the hottest. This is how he discovered infrared light. Herschel's early observational work soon focused on the search for pairs of stars that were very close together visually. Astronomers of the era expected that changes over time in the apparent separation and relative location of these stars would provide evidence for both the proper motion of stars and, by means of parallax shifts in their separation, for the distance of stars from the Earth. He soon discovered many more binary and multiple stars than expected, and compiled them with careful measurements of their relative positions.…

    The collapsing or dying of a star causes the strength of gravity to be so strong that light can't even escape the black hole. Because no energy can get out, people can't see black holes making them invisible. Space telescopes with special tools can help find black holes by observing stars that are very close to black holes act.…

    The Gravity Journal Analysis

    An astounding read, the Gravity Journal was a tear-jerking novel about the mental battle fought by, young Anise. A 16 year old girl who views herself as fat and ugly, although she is skin and bones, and she also self-mutilates when her depression becomes overwhelming. She comes from a rich but very dysfunctional family; she never calls her parents by any name except "Loathed" for her mother and "Witless" for her father, and they seem to fit the nicknames perfectly. Her mother, interested only in her possessions and her own life, shows little concern for Anise's struggle, insisting that she stop the melodrama and take responsibility for the way she acts. "WE'RE not the ones with the problems," she tells the hospital therapist, in an off-hand…

    Black Hole

    Black holes are not holes in space, nor are they uniform in size; they are unusual and diverse in nature. One can briefly describe a black hole as an object that is as dense as that no radiation can escape its gravitational pull. (Cosmic 132) In fact, its name is somewhat of a misnomer; black holes are in fact matter, and therefore tangible. One could even hold a black hole in one 's hand, assuming the gravitational force hadn 't crushed it. Black holes originally thought to have only been formed by supermassive stars collapsing in by their own gravity, to a mass smaller than the moon, also exist in many other forms. "Proposed varieties include primordial black holes...low mass objects formed shortly after the beginning of the universe; stellar black holes...and supermassive black holes, equivalent to millions of stars in mass and located in the centers of galaxies." (Cosmic 132) The "primordial" black holes have only been theorized; created by the big bang. (Cosmic 110) The Hubble space telescope, on the other hand, has photographed supermassive black holes. Our own galaxy, the Milky Way, has a black hole in its center, having…

He just moved to Houston with his single mother and brothers and sisters, he has had a hard time fitting in even if he is a smart and nice kid. Things are different than where he came from, in Houston it's all about nice clothing and shoes, which Malik lacked. He is bullied for his wardrobe and he would do anything for a new pair of "JC Jumpers", and he almost does. Carl, an enormous yet nice ninth grader who lives next to him is in a gang called the bullets wants to help Malik get new gear, and do it by beating up a basketball player and taking his clothes. This provides Malik with a moral dilemma, take the shoes or don't, this helps him develop a strong character. The perception of Malik and Carl to the reader change greatly over the course of beginning to end.…

    Black Hole and White Hole

    What are black holes and white holes? A black hole is a region of space from which nothing, including light, can escape. It is the result of the denting of spacetime caused by a very compact mass. Around a black hole there is an undetectable surface which marks the point of no return, called an event horizon. It is called "black" because it absorbs all the light that hits it, reflecting nothing, just like a perfect black body in thermodynamics. Under the theory of quantum mechanics black holes possess a temperature and emit Hawking radiation through slow dissipation by anti-protons. Most black holes are made when a giant star, called a supergiant, at least twenty times bigger than our own Sun dies, and leaves behind a mass that is at least one solar mass. Stars die when they run out of hydrogen or other nuclear fuel to burn and start to collaps. A supergiant star's death is called a supernova. Stars are usually in equilibrium, which means they are making enough energy to push their mass outward against the force of gravity. When the star runs out of fuel to make energy, gravity takes over. Gravity pulls the center of the star inward very quickly. A white hole, in general relativity, is a hypothetical region of space time which cannot be entered from the outside, but from which matter and light may escape. In this sense it is the reverse of a black hole, which can be entered from the outside, but from which nothing, including light, may escape. However, it is theoretically possible for a traveler to enter a rotating black hole, avoid the singularity, and travel into a rotating white hole which allows the traveler to escape into another universe. White holes appear in the theory of eternal black holes. “In addition to a black hole region in the future, such a solution of the Einstein equations has a white hole region in its past.” However, this region does not exist for black holes that have formed through gravitational collapse, nor are there any known physical…
