Is the amount of information taken in by a Blackhole, proportional to the amount given out?
Nereid said:Welcome to Physics Forums Olias!
I'm not sure that I understand your question ... in what way do you think that black holes could 'give out' information?
Nereid said:Ah, a question about the theory of black holes! If I may re-state it?
If a black hole evaporates completely, via Hawking Radiation, would the information content of a large enough chunk of space around the BH - encompassing all that went into the BH in its creation and all the radiation emitted in its evaporation - have a net gain of zero?
Let me add one question to yours: to what extent are both GR and QFT required for any answer to this question?
Loren Booda said:If info out equals info in, why does the great quantum number variety from infalling particles only manifest as angular momentum, charge and mass ("No-hair" theorem) at the surface and with the radiation of the evaporating black hole?
Olias said:Can Whiteholes spit out Blackholes?
If one uses the Chandereskar limits, and state that Stars are Whiteholes, the the collapse of a certain Star produces a Blackhole, thus White holes can emit Blackholes.
The Particle horizon of a Blackhole, where viirtual pair-production occurs in a pre-Galactic-Bang can be envisiged as a Blackhole spitting out White-Holes..to and fro, the Entropic Pendulum so to speak!
Kip Thorne and Hawking are about to resolve a long standing issue

Wave's_Hand_Particle said:The paper, although littered with spelling mistakes!..nevertheless deals with some really interesting problems with LQG.
The coming together of three major players in the development of this area of understanding, shows a very promising LQG evolution is still future bound.
Fotoni Markopoulou is of course of great interest, I, not only as an Observer of Femele Beauty, observe from a specific location, one that is paramount in the understanding of what we are and how we fit together.

meteor said:I took a quick peep to the abstract and was confused at first when I read about the Englert-Brout-Higgs mechanism, as I never had heard about this mechanism. The few entries in a google for this mechanism seems to hint that is a mechanism that grants mass to particles, so I have to deduce that is simply another name for the widely-known Higgs mechanism. Is hateful that differents names are assigned to the same process

and this:http://arxiv.org/abs/hep-th/0505266
has some interesting options?

Now it seems that certain Quantities that are infalling, shed "half" their mass when they are outbound?
So according to Relativity..the "outgoing" Energies can cover more ground/distance than Infalling Particles, they(particulates with motion away from the BH) must have "twice" the 'speed' and half the mass of particles that are heading towards a Blackhole!
There is an interesting 'Time' paramiter that that I have somewhere, which has a relevance to Parametric Downconversion of Symmetric Quantities around a Spacetime Junction..as Soon as I have finished with what I am working on at this moment, I will expand further..with links provided.

G.T.Horowitz has formulated the Tachyon Condensation (Evaporation from the black hole)..and the resulting Black-Strings are "non-visible" Tachyon Space-bubbles surrounding Galaxies for instance, black p-brane's ?
It is really interesting that when one has 'outgoing', particle evaporation, they cannot be observed, but can be static shrouds, or inferred by Galactic Motion, inertia?..Bubbles Of Nothing in the "Witten" Context, and have a different Time paramiter, similar to that of the Proton Decay guestimation of Witten Paper early 2002?
As I stated sometime ago, Witten moving the 'GOALPOSTS'!

If one takes the "Brane" Hypothesis, branes are concentric, dimensional borders. If one follows through the intersection of brane collisions:at galactic core's lay Blackholes, these have eminated from the collision of Branes, as the 2 brane passes each other, Gravitons appear and provide a nice background for the appearence of Matter:
two branes heading towards each other >>]+[<<
at an equilibrium moment of impact, the branes pass and Gravitons appear as a shroud/bubble horizon [<<-(+)->>] around the emerging Galaxy. As the branes move away, so does the gravitational shroud
[<<-((((+)))->>] eventually thinning out at the observational horizon:
..<<( ( ( ( (((+))) ) ) ) )>>..
Previous to a Galaxy appearing, the Blackhole follows the Brane Collisions.
If one rewinds Einsteins field equations, the geometry of the Blackhole will be identical to that of the Graviton scattering between two converging Branes, Gravitons appear on the Brane, as the branes then move away, so does the Graviton remain, close/on, to the Observational Horizon.
Now just as the light has a differing wavelength frequency, the Graviton must have a comparable variation, due to the fact that our Galaxy came into existence, at a different Time from other Galaxies? Gravitons are the Gravitational 'Observation-Time' components of all Galaxies.
'Our' Galactic Gravitons, as observed from us within our Galaxy, are always at our 'observational' horizon, we look outwards and away from the Milky-Way to observe our Graviton Shroud? Thus, looking at our Galactic Core, the Blackhole remnant, will not reveal any Graviton's, only remnant particle production.
If a new Galaxy suddenly appeared, within (inside) our observational horizon, then we could detect the Brane, and coupled Gravitons as they whizzed across our Galaxy, from the direction of the emerging new Galaxy.
The Brane ripple + Graviton particle are equivilent?

http://arxiv.org/abs/hep-th?0304079
with one or two goalposts needed to be shifted!
What came first. the proton decay or the Quark Superfield?
Nice one Carlo
