black holes

            
             What happens if you fall into a black hole? Science fiction writers often.
             speculate on what could happen if you fall into a black hole. A common suggestion is.
             that if you fall into one you might fall into another region of space-time. This of course.
             raises great possibilities for space travel. Something like this would be needed if travel.
             through the stars is to be a practical proposition in the future. Otherwise the fact that.
             nothing can travel faster that light means that the round trip to the nearest star would take.
             at least eight years. Of course how to choose your destination is not clear: if one could.
             pass through a black hole one might reemerge anywhere in the universe. Unfortunately.
             this scenario doesn't work. If you jump into a black hole you will most likely get torn.
             apart and crushed out of existence. If its any consolation to you, the particles that make.
             up your body will carry on into another 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 is crushed under its own gravitational force. While stars burn fuel, they produce an.
             outward push that counters the inward pull of gravity. But when the fuel is used up, the.
             star can no longer support its own weight and collapses, exploding in a tremendous burst.
             called a supernova. This exploding star throws off its outer layers, and the remaining core.
             continues to collapse inward at a rate equaling the speed of light - which means that no.
             light can escape from it and becomes invisible. It collapses to a small point in which all.
             of the star's mass is packed in with infinite density. The gravitational force is so strong.
             very near the black hole because all its matter is located at a single point in its center.

1. Theories of Black Holes

... force required to hold the stars and gas in their orbits (internet 1). Astronomers believe these massive dark objects in galactic centers to be black holes for at least two reasons. First, it is hard to think of anything else they could be: they are too dense and dark ... extremely high temperatures and density in which the universe is thought to have originated roughly 10 billion years ago (Hawking 161). These so-called mini black holes, unlike the more massive variety, lose mass over time and disappear. The idea is that subatomic particles such as protons and their antiparticles (i.e....

... an atomic particle to those equivalent in mass to millions of stars. Black holes come in all sizes, not just the 10-solar-mass regular size. Globular clusters may contain maxi-black holes, with masses of several hundred solar masses. Mini-black holes far smaller than stars may also exist. How are black holes formed? Black holes may form when stars are so overwhelmed by the force of their own ... human being from another. But in 1975, investigators proved the last of a series of theorems, showing that mass, spin, and possibly electrical charge are the only black hole properties allowed b...

... line, it can no longer escape the gravitational force of the black hole (Hawking, 87). In 1915, Albert Einstein set forth the first proposition of black holes in his "Theory of Relativity". In the 1934 three physicists, Volkoff, Snyder and Oppenheimer, proved the legitimacy of black holes mathematically. In recent years black holes have become an imperative part of science and the over all understanding ... of the universe.

... galaxies, including the Milky Way. Direct proof remains that energy is vanishing from volumes of space without a trace. Black holes operate by mass, radiation, surface area, and gravity. Black holes have no hard surface for matter to accumulate, so matter is swallowed and disappears forever. The event horizon is simply ... agrees with estimates of how quickly the ordinary star is losing mass to its companion, the black hole. Thus, x-ray binaries could be the best proof that stellar-mass black holes exist. Black holes are the most compact objects in the universe. Near galactic centers, sta...

... 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, no one knows the real truth about black holes and we may ever know. These "galactic wells" are quite possibly how the Universe formed and how the Universe ... to about one hundred million degrees Celsius. When the gas gets this hot it starts emitting X-ray beams. This is one way that we can detect black holes. Space probes orbiting the Earth take survey of X-rays and once they are found; we investigate the source of the beams (Whitney 4...
