Re: Yale Astronomer Discovers Upper Mass Limit for Black Holes

Ooops, I though I was replying to Modest, on the discussion of the Dominium Model on the Alternate Theories board in the Physical Sciences group. Modest had just shown three articles, and this was one of them. I'll include my critique here as well as in the full response to Modest.

The third article http://hypography.com/forums/astrono...ass-limit.html although interesting, I do not agree with the absolute soundness of the ultimate conclusions being made by the scientists referenced. Essentially this article represents an account of observations of the last portion of the AGN growth cycle as the process slows down. (Wow, things have come a long way in the past decade, such observations, though not surprising, is truly news to me!)

Although I find it totally cool that folks have observed the last phases of AGN growth… I do not agree with the final conclusion that the statistical survey conducted can claim that there is a maximum size/limit for black-hole growth. Quite to the contrary, to me, all this survey does is confirm the Dominium assumption that self-assembly would have applied from earliest on in the development of the Universe. Systems that self-assemble do so predicatably and uniformly. The notion that ultimate galaxy size and the assertion that all protogalaxies contain micelles (that will ultimately dam-up the gate-interface) is central to the understandings of systems that self-assemble. The repercussion from this would result in a uniformity of size of resulting quadrants—exactly what appears to have been observed.

Therefore, this article seems to lend credit to the notion of self-assemblage (not the stated max-size for black-holes.) Besides, the notion of a maximum size for black-holes is contradictory given the premises that have been established on this thread in moves 6-7; if black-hole material is the most stable phase of existence, then its size (micro or super-duper) would not affect its degree of stability. No other phase is dependent on sample size; there’s no reason to think that black-holes would be.

Again, as this article goes on, Natarajan says, “They shut off at every epoch in the universe." Again, this assertion confirms the earlier assertion that all dominia would contain micelles, therefore all seed AGN would eventually be turned off.

This article is the only one that began to talk about the popular explanation for this observed paradoxical anomaly (AGN stopping eating and subsisting in the most mass-dense portions of galaxies) when Natarajan goes on to say
Quote:
”the black holes eventually reach the point when they radiate so much energy as they consume their surroundings that they end up interfering with the very gas supply that feeds them”
(This is the “blowing” part of the popular explanation that CraigD mentioned on post 72.) As mentioned in the post immediately before this one, this popular-explanation raises more questions than it answers.

Thank you Modest. All three of the articles were very interesting, tangible, and based on current data. I learned a few things with that read and thoroughly enjoyed myself. If there are any concerns raised by my assessment of this data and how is combines/jibes with the Dominium, I’ll be happy to delve deeper.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
