Chaisson's Astronomy: The Existence Of Black Holes

The existence of black holes was first theorized by John Mitchell in 1783. Mitchell accepted Newton’s laws of gravity and suggested that light escaping from the surface of a star would have its speed reduced due to the gravitation pull of the star, and therefore if a star’s gravitation pull was strong enough even light would not be able to escape.[1] Using the approximate speed of light he reasoned that if an object was approximately 500 times the mass of the sun light would not be able

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

Over the last semester, our class has gone on a journey throughout space. This journey has grown our knowledge and imagination of what space holds for humanity. With this class, we have been inspired to look past our own planet to the future opportunities the the stars hold. Just as this class has lit the fire of adventure for space in us, our group went to Legacy High School to present to both of Mr. Wold's AVID class, pictured below, where we tried to inspire the group of seniors about the wonder of space before they took their next step in life. To do this, we presented on one of space's biggest mysteries, Black Holes.

Stephen Hawking a well-known theoretical physicists, has contemplated the conundrum of whether or not information is destroyed at the horizon of black hole.

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

There are two main reasons why humans cannot see black holes and one of the reasons is that black holes are black and cannot be seen because they blend in with the darkness (“Black Holes – NASA”). The second reason is that they are too far away to be seen even with incredibly powerful telescopes (“Black Holes – NASA”). There are also some tools that allow people to see the effects of what a black hole can do to different kinds of matter in space near them (“Black Holes – NASA”). By using a radio telescope in the Southern Hemisphere scientists can see the particle jets coming out of a black hole and have made a detailed drawing of what it looks like (“Black Holes – NASA”). Scientists

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.

One night there was a little boy named Zach, and his parents Mary, his mother, and John, his stepfather. They lived in the small town of Roscoe, MO. This small town is ten miles from the nearest emergency room. One night the poor boy got sick.

Prior to this symposium, physics was not very high on my interest list. However, due to both Dr. Neil Cornish and Dr. Nicholas Yunes, they ignited a strong interest in this field in me. Both professors discussed black holes and experimental tests on certain theories in an extremely enthralling manner. Not only were their presentations interesting, but they succeeded in altering my previous viewpoint on physics. Due to

I walked around cautiously hoping not to get caught. Dang. Walked around three hours before I got that baby. God. I was like a tiger watchin its prey. Ahh I can't get over wutta beauty she was, the switchblade I'd always wanted. All black n silver shiney. I wanted it. So I took it, gally, I didn't care if I was stealing, I wanted her badly, and I got it. Anything I ever want, I get. The workers were staring at me the whole time so I had to be careful. As soon as she was in my hands and I walked out the door I felt like I'd just won a grand prize of some sort.

Some of the fundamental singularities that are not clarified are gravity, dark matter and dark energy, neutrino masses, and matter anti-matter symmetry. Throughout the standard model, it refers to the ideas of hypothetical applications that are required to explain the insufficiencies of the standard model. This includes the nature of dark matter and dark energy, and also the origins of mass. Another error that may lie within the standard model is the inconsistencies and mathematics that lie within the model itself. The standard model is majorly inconsistent just like the theory of general relativity, they both interrupted by the conditions of other aspects revolving around these ideas, such as the Big Bang and black hole horizons. Despite the standard model being one of the most successful and practical theories of particle physics, it is however not perfect.

Ted Bunn's webpage over black holes does a good job at informing the reader on black holes without over complicating the explanations. He even goes into extra detail about black holes, like how the experience would be if someone were to enter the gravitational pull of one. Additionally, he does a good job at entertaining the reader with his fascinating details and hypothetical situations. As Bunn entertains us he still remains a down to earth informer and reminds us that the information though true will be

Roy Kerr’s theory on the rotating black hole, along with the rotating singularity seemed to convince many, even before black holes were not believed to exist. However, modern work published in late August 1998 by Piran and Shahar Hod has seemingly ended this idea. They used complex computer simulations to study how an electrically charged black hole might form and how the singularity would behave. They showed that a process known as "mass inflation" violated the Kerr hypothesis. When a particle moves towards the black hole, the apparent mass of the hole increases to infinity as observed by the object. Thus, causing the singularity to go
