... there were few jobs for mathematics graduates. He wanted Hawking to attend University College, Oxford. It wasn't possible to read mathematics there at the time. Then Hawking decided to study physics and chemistry. Despite his headmaster's advice to wait until the next year, Hawking was awarded a scholarship after taking the examinations. When he went to Oxford University he thought that university ... ...

... mass at the center of the galaxy, about 2.6 million times that of the sun, fit into a space no larger than 93 million miles across. According to the known laws of physics only a black hole could be that dense. Astronomers theorize that most galactic cores have black holes. One way to study a black hole is for scientists to look for gas swirling ... ...

... , 2002). Like White Dwarfs, Neutron stars also have a maximum possible mass which would be analogous to the Chandrasekhar limit. The quantitative calculation of this mass is uncertain however, because nuclear physics is not complete. Nevertheless, there are still good arguments that no matter how strongly repulsive nuclear forces become at huge densities, they cannot resist gravity if the mass of an ... ...

... of an atom. Any light rays emitted by the star are wrapped around the star. Because no light can escape, it is called a black hole(Davis 209). The laws of physics are time-symmetric, which baisicly means that if there are objects called black holes into which things fall into but not get out, then there ought to be other objects ... ...

... density of matter at the center becomes essentially infinite. Thus, what is meant by "a hole in the fabric of spacetime" is: a tiny region of space where the known laws of physics break down. A black hole is a region of space so tightly packed with matter, that nothing, not even light can escape. Hidden at its center is a tear in the fabric of ... ...

... by the amount of matter it has swallowed. Great mass-produce so much curvature that the space would close up around the star, thus forming a black hole. No principle of physics determines how massive a black hole is capable of being. The mass of any object, except a black hole, is limited by its ability to hold up under its own weight. Black ... ...

... age old questions. Perhaps, some day when our technology permits the inferences and uncertainty of astronomy can be figured out and theories will be as concrete as the laws of physics, mathematics, and the other sciences. Until then astronomers will continue to infer from the evidence at hand and uncertainty will dominate a field where "revelation is simultaneously exposing innumerable new questions ... ...
