... that if light cannot escape, nothing else can either. The result would be a black hole. The boundary of the black hole is called the event horizon. What exactly is the event horizon? The essence of a black hole is the event horizon, the point of no return. At the event horizon, something would have to travel at 3 the speed of light to escape from the black hole. Since nothing can travel that fast, nothing ... In the long run, every black hole in the universe will evaporate this way. For a black hole with the mass of the sun, this could last for about 1066 years. How could radiation escape...

... problem. What this means is that it is impossible to use the laws of physics to predict the structure of the region after the Cauchy horizon. This breakdown of predictability has led physicists to hypothesize that a singularity should form at the Cauchy horizon, forcing the evolution of the interior to stop at the Cauchy horizon, rendering the idea of a region after is meaningless. Recently this hypothesis was tested in a simple black ... This is because, as crushed as they are, the neutrons also resist the inward pull of gravity, just as a white dwarf's electrons do. A black hole is on...

... into several different stages. Usually if the star is small in mass, most of the gases will be consumed while some of it escapes. If the star was to have a larger mass however, then it may possibly Supernova, meaning that the nuclear fusion within the star simply goes out of control causing the star to explode. A black hole is one of the last options that a star my take ... . Not any star can become a black hole. For instance, the possibility of our sun becoming a black hole is highly unlikely, simply because it is too ... . When a black hole absorbs a star, the star is first pulled into...

... never see that person reach to center of a black hole because the light that would be required to see him would itself never be able to escape the black hole. If the light were never able to leave the black hole you could never see him enter the black hole. This phenomenon would not last forever though, because black holes evaporate because of mass lost through ... a process to be discussed in part 4. Therefore the person standing on earth would see the person flying into the black hole actually enter the black hole a faction of a second before the black hole finally evaporated. At whic...

... there is anything that is still a mystery. When scientists are looking for something new to discover or research, where do they turn? One of the last remaining mysteries in the Universe are black holes. These super-dense bodies in the Universe leave a lot to be discovered. We have basic theories on what we believe happens to black holes and how they are formed; however ... as dense as a neutron star. This makes the dent that a black hole takes so much bigger that it is more of a well than a dent (Pickover 91). Once the gas moves into the accretion disk it reaches a point called the even...

Hawking's research centered on Black Holes, and from the late 60's onward he has been in the forefront of Black Hole research. One discovery of Hawking's is that Black Holes emit radiation.

... universe(Hawking 116). But what exactly is a black hole? A black hole is baisicly thought to be the last evolutionary stage of massive stars-at least fifteen times as massive as the Sun. Astronomers believe that a black hole forms when a massive star runs out of nuclear fuel and ... and found that black holes are not completely black. He discovered that they send out radiation particles at a steady rate. He found that the uncertainty principle, which says that particles cannot have both a well-defined position of a particle and a well-defined velocity, allows particles to travel ... for...
