Black Holes Lab

”GX 339-4, illustrated here, is among the most dynamic binaries in the sky, with four major outbursts in the past seven years. In the system, an evolved star no more massive than the sun orbits a black hole estimated at 10 solar masses. “ [5]

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

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

Since the discovery of the “first” large KBO, 1992QB1, in 1992 by Jane Luu and David Jewitt (jew-it), a few others have been identified. In 2004 using better telescopes, astronomers discovered another KBO which they named Sedna. This was followed by discoveries in 2005 and 2008. In 2005 a KBO slightly smaller than Pluto was identified and named Eris. It was the discovery of Eris which has its own moon that led to Pluto being reclassified as a dwarf planet rather than the ninth planet in our solar system. In 2008 two more objects categorized as dwarf planets were discovered. One is named Makemake after the Polynesian creation god and the other is named Haumea after the Hawaiian goddess of fertility and childbirth. The distance from Earth and the small size of the objects in the Kuiper Belt make them very difficult to see and study. To get a closer look at the objects, the first mission to the Kuiper Belt was launched in 2006 by NASA. The New Horizons spacecraft had reached Pluto about 10 years later in 2015 providing the first up close glimpse of a Kuiper belt object. The New Horizons spacecraft continues to push further into the Kuiper Belt and information from this exploration is still being analyzed.

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.

The super strong gravity of a black hole pulls gases off nearby stars with such a force that the gases give off x-rays as they form an accretion disk of matter that spirals into the black hole. (Gallant R ., 2000).

Have you ever heard of something getting sucked up in a black hole? Did it ever cross your mind as to what a black hole actually was? Well, a black hole is a rather large star that underwent a supernova explosion and since there was no gravity it collapsed in on itself. It is a big hole of nothingness that stays in outer space but does not suck up everything. Now lets get into more of the facts about black holes.

The sixty-symbols website has quite the collection of intriguing astronomical theories and interviews, but I specifically chose that of the black hole that contains interviews by Omar Almaini, Ed Copeland, Tony Padilla, Meghan Gray and Mike Merrifield from the University of Nottingham. The video began by a man revealing to his audience that he is often questioned about his personal opinion on black holes, which he informs us that “of course” he sees them as frightening and intimidating but goes on to refer to them as “cuddly”. Upon further explanation he points out two small (but different sized), round, black balls of fabric (that seemed to be knitted) that were gifts for his sister-in-law and they are meant to be representation of black holes with their solid black exterior. This seems like a useless example, but after thinking about it more critically I realize that I wasn’t

The first black hole was discovered in 1971 and John Wheeler, an American astronomer, coined the term black hole in 1967 (“Black Holes: Facts”). Black holes are formed out of pieces of a star that have exploded in a supernova explosion (“Black Holes – NASA”). They are also formed when two stars have a stellar collision

Black holes should probably not be called black holes. In fact, black holes are anything but empty space. Black holes are a great amount of matter packed and squeezed into a very small area. The result of this amount of matter squeezed into a small area results in a gravitational field so strong that nothing, not even light, can escape.

The study of pulsars began when Antony Hewish and his students at Cambridge built a primitive radio telescope to study a scintillation effect on radio sources caused by clouds of electrons in the solar wind. Since the telescope was designed to record rapid variations in signals, in 1967 it recorded an unexpected source. Jocelyn Bell Burnell noticed a strong scintillation effect opposite the sun, where the effect should have been weak. An improved recorder was installed, the signals were received again as a series of sharp pulses with intervals of about a second. In 1968 it was clear that the team discovered a rapidly spinning neutron star, a remnant of a

For my Senior Project, I am submitting a lab which I completed in AP Chemistry. In the Gravimetric Analysis of Calcium and Hard Water Lab my lab partner and I conducted an experiment in which we calculated the mass of the precipitate formed by the mass of the isolated analyte present in the reactants before the reaction. During our experiment, we used resources such as graduated cylinders, sodium carbonate, bunsen burners, an analytical balance, watch glass, filter paper, a funnel, tongs, and an oven. The lab equipment allowed us to effectively precise measurements of water hardness. For example, the analytical balance gave us a more precise measurement than a triple beam balance would. The temperature of the burners as well as the temperature

Black holes are interesting because of the history of how they are made Fact 1: black holes are formed from a dying star Fact 2 : black holes can be big depending on how big the star was Fact 3: if a black hole meets another black hole it will cancel each other out Body Paragraph:

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.
