... . Is this a coincidence? After his studies at St. Albans School, he attended University College, Oxford. He wanted to study Mathematics, but because it was unavailable at Oxford, he concentrated on Physics and earned a degree in Natural Science three years later. Stephen went on to Cambridge to do research in Cosmology. After attaining his Ph.D., he became a Professorial Fellow at Gonville and ... Caius College. He left the Institute of Astronomy to become a professor at the Department of Applied Mathematics and Theoretical Physics at Cambridge. He has held the post of Lacasian Professor...

... 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 ... ...

... 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 ... ...
