Black Holes: The Power Source for Future Space Travel? ... Now, with modern theories of black holes, trips to other solar systems may be possible at nearly the speed of light. Black holes were only proven to exist within the last twenty-five years and were only really considered to exist for the last seventy-five years. ... Black holes generate tremendous amounts of energy in several different ways, and so can be harnessed in several ways to generate usable power. In order to understand how energy can be created from black holes, one must first have an understanding of black holes themselves. Black holes are formed by matter being crushed within a certain radius (call the Shwarzchild radius or event horizon). This radius can be calculated by the equation r = 2GM / c2, were G is Newtons gravitational constant, c is the speed of light, and M is the mass of the black hole. ... The gravitational field around a black hole will act same as an object of identical mass, so if the sun were to suddenly … [become] a black hole … would the earth go plummeting into it? No, it would continue on its orbit … things just get interesting close to the black hole (Jebornak, 1998). There are three types of black holes that scientist currently believe are capable of becoming future power sources: Schwarzschild black holes, Newmann black holes, and primordial black holes. Schwarzschild black holes are the simplest black holes because they do not rotate and have no charge. The Newmann black hole, on the other hand, rotates and has a charge, but like the Schwarzschild black hole can have varying masses from a couple times our suns mass to several billion times the mass of our sun. Primordial black holes were first theorized about In the year 1973 [by] Stephen W. Hawkings [who] postulated that in the early moments of the big bang, miniature black holes would have been created with masses around that of a small mountain, 2 * 10^13 kg (Wagner, 1999). These black holes could resemble a Schwarzschild black hole or Newmann black hole or even be a hybrid of their properties by rotating but possessing no charge. Newmann black holes have an ellipsoid (three-dimensional oval) around … [them] called the ergosphere, and it connects with the black holes outer event horizon at the poles of its axis of rotation (Jebornak, 1998). Once matter enters the ergosphere, it begins to rotate along with the rotation of the black hole; this forms what is known as an accretion disc.
