Description:

This paper explains that in the universe, few elements are weirder than black holes, a celestial body made of material so dense that nothing can easily escape its gravitational field, not even light. The author points out, that for decades, theorists considered them mere mathematical constructs, unavoidable consequences of Albert Einstein's theories of relativity; but there is no reason that they cannot exist in nature and, over the last four decades, evidence has mounted that suggests they actually do exist. The paper relates that, although black holes are totally invisible and there is no way to see them directly, they can be detected indirectly (1) by observing the radiation from the bright-burning accretion disks, which radiate on all electromagnetic frequencies especially on the X-ray bands, and (2) by observing their gravitational effects on other objects.

From the Paper:

"Another important feature possessed by many black holes is an accretion disk, a torus around the event horizon formed by infalling matter as it spirals toward the singularity. Because of the energetic nature of the infall-think of the whirlpool formed as water drains from a bathtub-accretion disks usually emit all sorts of radiation, including visible light. The only other features black holes are reliably theorized to possess are angular momentum (rotation) and occasionally the odd electric charge or magnetic polarity, a consequence of eating too many charged particles"
