    B Black hole question

    From: http://casa.colorado.edu/~ajsh/hawk.html in part reads: "Evaporation of a mini black hole Black holes get the energy to radiate Hawking radiation from their rest mass energy. So if a black hole is not accreting mass from outside, it will lose mass by Hawking radiation, and will eventually...

    B Black hole question

    Yes; the equation would be: "Minimum Mass = No Black Hole Anymore = (Mass=0)"...:biggrin:

    B Black hole question

    True, and the smaller the BH, the more intense the Hawking radiation. Regarding small BH's, someone coined the (now) common phrase: "Black holes are white hot." Also there are two opinions on the "finality" of small BH's; one is "evaporation" you mention above and the other is that once a...

    B Black hole question

    The Event Horizon (EH) calculates to spherical, but all Black Holes (BH) rotate; none can be "non-rotating". That was shown long ago. Actually, Hawking Radiation (HR) "comes from" the edge of the EH which is the classical 2GM/c2. This EH is at the same radius for a rotating BH as it is in the...

    Are black holes explained by complex analysis?

    From Post 2: What else can I say? Other people refer to "zero-point" something(?) but I'm saying no such thing. No reply is needed, PLEASE!

    Are black holes explained by complex analysis?

    You didn't get my meaning. I will never "accept the conclusion of infinite density" OR accept any assumption of zero volume. I never called any "volume" zero; it is exactly that which I have been posting about.(Against?) I think that we generally agree but have a "semantics" problem going on...

    Are black holes explained by complex analysis?

    :uhh: But, my point is that there is nothing with zero volumn! If zero-volumn is considered, then whatever it may be called just doesn't exist. This is "General Astronomy" so go to some other more advanced forums, or many recent (last 5 years) papers published by "well-known" astrophysicists and...

    Are black holes explained by complex analysis?

    Take any sized finite volumn you can think of; maybe a sphere with a diameter of 1 Planck length, or a basketball. How can you fill that volumn to infinite density without using an infinite amount of mass? I can't think of a way to accomplish that.(?) That's how it implies infinite mass. p=m/V.

    Are black holes explained by complex analysis?

    Agreed, but what I meant to explain is that a "signularity" as defined 10-15 years ago doesn't exist. The "center" of a BH has a finite size with a very large density but not an infinite density. The gravity of the large mass still exists and the measure of the mass determines the EH boundry...

    Are black holes explained by complex analysis?

    To any "outside observer", time appears to stop at the Event Horizon (EH) which is an "effect" at: 2Gm/c^2 or at the poles (only) of an "Ergosphere" where the gravity curves space-time back into a "loop" returning to the interior of the EH boundry. (That is definitely a non-technical...

    Are black holes explained by complex analysis?

    I'm not sure what you mean by "pole" but most recent accepted theory is that the "center" of a black hole is not a zero-point singularity. The "center" must have a finite size of at least a Planck length: (1.61624 × 10-35 m). Infinities simply do not work in math, and a zero-size point of any...

    The Limitations of Intergalactic Travel

    The term "necro" simply means dead.

    Are craters on the moon randomly distributed?

    There is no "dark side of the moon". All of it is in sunlight once every lunation, just as Earth has no dark side.

    Please help. Supernovae database?

    This only goes back to 1885, but it is a LONG list. http://cfa-www.harvard.edu/iau/lists/Supernovae.html
