Essays on Event Horizon

Introduction

A black hole is a region in space-time, the gravitational attraction which is so large that it can not leave even objects moving at the speed of light, including photons of light itself. The boundary of this region is called the event horizon, and its characteristic dimension - the gravitational radius. In the simplest case of a spherically symmetric black hole Schwarzschild radius is equal to it. Theoretically, the possible existence of such regions of space-time should be of some exact solutions of Einstein's equations, the first of which was obtained by Karl Schwarzschild in 1915. The exact inventor of ...

Interstellar: Film Cuts

For those who have seen Interstellar it is a cinematic adventure only matched by the amount of plot holes found throughout its story. The viewer is taken on a whirlwind celestial journey through space, and time, as relativity and our imaginations are warped. There is so much happening in the 2:49:00 movie, small cinematic gestures, such as film cuts, got lost in the grandeur. However, several scenes with three in particular, allowed film cuts to be noticed for the tools they are. Well into the film, after the explorers had landed on their first planet, an ‘after action’ cut is ...

A wormhole theoretically is known to be a passageway through space-time that can be used to create short routes for extensive journeys that go across the universe. Wormholes are mainly forecasted through the general relativity theory. Wormholes have been forecasted come with the dangers of high radiation, unexpected collapse, and unsafe contact with alien matter. A wormhole when viewed depicts a tunnel that has separated ends in space-time. It can be pictured as a two dimensional tube surface that connects various parts of the surfaces (Nelson, Peter & Rohitash Rao 67). There are no evidences that are observable about wormholes according to ...

No one has ever seen a black hole with their own eyes but everyone has heard about black holes. New technology for making telescopes has helped scientists learn more details about black holes but the principles of physics give us our basic understanding. When a massive star dies the type of black hole formed is a stellar black hole. The star caves in on itself when it dies forming a black hole. (Figure 1) When a star with a huge mass dies, part of the start explodes into space – that is a supernova. The area of a black hole is small because the dead star’s ...
