space there is still a great deal of research involved, though often slow going, as it relates to uncovering the mysteries of black holes. In the following paper we examine
some scientific articles, beginning with articles dated in 2001, discussing the discoveries and the research involved in the past few years. Black Holes The first scientific discussion to
be examined comes to us from May of 2001. In a Science article we find that "Black holes are now widely accepted as the cause of many phenomena in astrophysics,
from supermassive black holes at the centers of galaxies to stellar-mass--sized black holes in x-ray binaries (1). Black holes are the simplest objects physics can think of to explain the
behavior of these systems" (Dolan 1079). At the same time, however, it seems that there exists "the theoretical possibility...that these objects may be more exotic than black holes. Recent observations
have come tantalizingly close to ruling out more exotic objects in x-ray binaries, providing the best evidence yet that stellar-mass--sized black holes must exist" (Dolan 1079). While relatively scientific
in its content, the article indicates that "In compact stars, the inward force of gravity acting on the stars outer layers is balanced by the pressure generated by the Pauli
exclusion principle acting on its electrons (in white dwarfs) or nucleons (in neutron stars)" (Dolan 1079). Yet, when "No equilibrium radius exists, and general relativity predicts gravitational collapse to a
point singularity" we are provided with a black hole (Dolan 1079). This article further argues that "The black hole is not visible to the outside world, however. Schwarzschild found (3)
that according to general relativity, no signal can reach the region of space-time outside the Schwarzschild radius" (Dolan 1079). Within these black holes lies the speed of light and
