Black Holes Essay by JPWrite

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.
