Re: A Cosmological Theory - Extending on the Big Bang

[wiki-link]
Starting from theorems proved by Stephen Hawking, Jacob Bekenstein conjectured that the black hole entropy was proportional to the area of its event horizon divided by the Planck area.

S_{BH} = \frac{kA}{4\ell_{\mathrm{P}}^2}

where where k is Boltzmann's constant, and \ell_{\mathrm{P}}=\sqrt{G\hbar / c^3} is the Planck length.

The black hole entropy is proportional to its area A. The fact that the black hole entropy is also the maximal entropy that can be squeezed within a fixed volume was the main observation that led to the holographic principle
[end wiki]
I found this interesting and agreeable to the overall concept, that a black holes stability is based upon the surface area.

Although, what I have been reading is that for a black hole, a smaller surface area provides a greater rate of emission than a larger surface. This tends to go against the expectations of the theory. However I read over some issues that have not been solved, and I wonder what kind of results would be produced if the surface area was greatly bloated.

When you go, you may take nothing with you except that which can be held in your heart. Fill it wisely.

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!
