Schwarzschild radius

A Metaphor for War: Schwarzschild Radius and Black holes Connie Willis communicates that a black hole is akin to war through the use of a number of metaphors in her story Schwarzschild Radius. Schwarzschild Radius is about a World War One veteran, Rottschieben who is recounting his time in the war to a curious college student who wished to know about his time working alongside the physicist that is attributed with the discovery of the Schwarzschild Radius. Willis uses comparisons such as temperature, what an observer would see when a black hole collapses, and the lack of information that can get in and out of the war zone and black holes as ways to connect a black hole to war. In the story, during the recounting of Rottschieben’s experience in the war his vision is shown to be becoming redder and redder as time goes on, until everything comes to a head, and the bunker…

One of the most strange and interesting things in my opinion is called a black hole. The most interesting thing about them is that they can completely make something disappear but the item keeps it's original mass. That is why I will be writing about black holes in this paper. People have been studying black holes for a long time. In 1915 Albert Einstein published his theory on black holes. But the same year Karl Schwarzschild proved that theory correct. And people have performed more and more…

Intro The universe house's countless dangers. Some are small such as wild fires or sink holes. These natural hazards seem large to us but compered to a black hole they are extremely minute. The idea of earth being swallowed by a black hole is terrifying one. One of the things that we fear most about black holes is how little we know about them. We know that they have incredibly strong gravitational force. By the time you got anywhere near it your atoms would have been ground up and used to fuel…

One concept that has interested is dark matter and dark energy. Dark matter is the thing that makes it possible for galaxies to exist. When astrophysicists and cosmologist calculated why the universe is structure the way it is, it became clear that there’s just not enough normal matter. The gravity of the visible matter is not strong enough to from galaxies and complex structures. The starts would more likely be scattered all over the place and not form galaxies. Therefore, cosmologist concluded…

A black hole is defined by the force it would take to escape the gravitational pull of the black hole.gravitational pull exerted upon an object. Anything that wants to escape earth's gravitational pull must go at least 11 km/s, no matter what it is. The escape velocity of an object depends on how compact it is. A black hole is an area of extremely high gravity where it is impossible for even light to escape. Black holes are formed when huge amounts of matter are condensed into small…

will then overpower the other forces, thus creating a black hole. It was in the 1700’s that John Michel and Pierre-Simon Laplace first considered the possibility of a gravitational field too strong for light to escape. Black holes were widely considered a mathematical curiosity and it wasn’t until the 1960’s that actual theoretical work showed there was a generic prediction of relativity. “Dark Stars” were mostly ignored due to the public's inability to understand how a massless wave such as…

For 13 years, the scientists of LIGO—the most ambitious, and expensive, project in the history of the National Science Foundation—had been waiting. LIGO, the Laser Interferometer Gravitational-Wave Observatory, has been twenty-five years and more than half a billion dollars in the making. It involves 900 scientists and engineers, including many whose entire careers have been spent designing, building, and preparing to analyze data streaming in to LIGO. Their goal: To confirm, once and for all,…

Interstellar: Black Holes Jodel Erickson May 15, 2017 Mr. Kopanke Apa Scientific Understanding of Black Holes “A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape” (Dunbar, 2015). This occurs because there is matter being pressed into a small space. Some black holes are the results of dying stars. Black holes are invisible because no light can escape. But, scientists have space telescopes with special instruments can…

importance of inertial and gravitational properties of mass play in the discovery of general relativity. Well, these are coordinating systems that accelerate to each other, so therefore you need the gravitational fields for the theory of general relativity. Albert discovered gravitational waves in 1916. Space time fabric is a way to visualize the existence of gravitational waves and see how they work. Gravity corresponds to the “bending” of the fabric because the twist of it is…

significant dilation where 7 years is equal to one hour, a strong gravitational field, close to that of the Schwarzschild radius of a black hole, would be needed. This is evident through Newton’s formula; 〖 F〗_g=(Gm_1 m_2)/r^2 where; F_g=force due to gravity G=Universal gravitational constant (6.674 ×〖10〗^(-11)) m_1=first interacting mass m_2=second interacting mass r=distance between the centre of two masses From Newton’s Gravitation Formula, the force is inversely proportional to the…
