Scrap-Studies of Black Holes!

August 19, 2010 at 9:03 PM (Uncategorized)


I remain fascinated with studies of outer space, focusing on the topic of black holes.  I took a little time to pull up some information from various web sites, reading about some of the latest, related theories and studies.  Several pertainable postulates are presented.

I was seeing that current understandings of black holes have them divided into four different designations, or size ranges.  They begin with stellar-mass black holes, which are anywhere from five to ten times as large as The Sun.  Next are intermediate-mass black holes, and these are 100 to 1,000,000 times the mass of The Sun.  Supermassive black holes, the ones that seem to attract the most attention lately, are anywhere from 1,000,000 times to over a few billion times the mass of The Sun.  Finally, ultramassive black holes are the largest, reaching the extreme rates that are at or are beyond tens of billion mass levels of our Sun!

Black holes form when stars that are at least six times the size of The Sun, or larger, collapse after all of their energy is exerted.  When these stars explode into supernovae, their core regions implode.  As the cores are collapsing inward, the surrounding forces of gravity grow stronger.  Eventually, the collapsed star reaches a singular point that is called the singularity, around which is the ominous void of a black hole.

As stated earlier, stars like The Sun can not become black holes when they die.  These fascinating structures have to result from larger stars.  These stars have to go supernova, then collapse into black holes.  The remaining size of the resulting black hole is measured in what is being called The Schwarzchild Radius.  Studying scientists are using this term to label the distance between the edge of the event horizon and the central singularity of black holes.

Well; anyhow.  I felt like jotting all of that into what I wanted to present as my blog entry for the evening.  This particular topic is very fascinating to me, and I think that I will read more information about it tonight.  The science channels ususally present some forms of related programs, so I will watch to see if anything is showing tonight!
