Is Blackhole Symmetry Proportional to Information Exchange?

Click For Summary
The discussion revolves around whether the information absorbed by a black hole is proportional to the information it emits, particularly through Hawking radiation. Participants explore the implications of black holes evaporating completely and question if the net information exchange results in a zero-sum scenario. The conversation also touches on the relationship between general relativity and quantum field theory in understanding black hole behavior. Additionally, concepts like the "No-hair" theorem and the potential for black holes to act as white holes are examined. Overall, the thread highlights ongoing debates in theoretical physics regarding black hole information dynamics and their implications for our understanding of the universe.

Should actually mentiont that whilst Rovelli took the Regge route, witten took the "sort-of" route :http://arxiv.org/abs/gr-qc?0306083

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 :approve:

For an interesting overview of "junctions" look here at Marolf:http://arxiv.org/abs/gr-qc/0505048

Just a bit of abstract text from the paper to spurn interest:
The study of boundary layers (i.e., singular sheets of sources with zero thickness) is of longstanding interest in both electromagnetism and general relativity. In addition to approximating smooth solutions such as domain walls,
the class of “thin-wall” solutions provides a useful laboratory in which to explore new phenomena. For example, thin-wall spacetimes have been of much use in investigating so-called “braneworld” scenarios, first suggested in the modern context in [1, 2, 3], in which the visible 3+1 universe is confined to a submanifold of some higher dimensional spacetime. In particular, the phenomenon by which gravity can become localized along such a domain wall was discovered by Randall and Sundrum [4, 5] by considering the limit of an infinitely thin wall. Thin-wall spacetimes are also historically of interest in exploring gravitational collapse (see e.g. [6]), typically in the context of spherical shells.


Thin-wall spacetimes are also historically of interest in exploring gravitational collapse (see e.g. [6]), typically in the context of spherical shells.
Although the stress tensor must diverge at an infinitely thin wall, the associated singularities in Einstein-Hilbert gravity are often mild. For familiar cases, these singularities serve merely to simplify the equations of motion by turning the differential equations for the fields into finite difference equations, known as “junction conditions,” governing the discontinuities of various fields across the thin wall.

These recent papers are the defining moment of new interpretation?:http://arxiv.org/abs/gr-qc/0109035

http://arxiv.org/abs/astro-ph/0509230

Interesting linking to the "no singularities" in the first paper.

Plus this is giving creedence to one or two or three of my theories which caused my being banned, at least three times! :biggrin:

What goes in must come oout! quote from this interesting paper:http://uk.arxiv.org/abs/gr-qc/0506126


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.

New theorem paper:http://arxiv.org/abs/gr-qc/0509063 :rolleyes: :blushing:

The result of Rovelli's latest paper above, equates to the Vacuum of Space between Galaxies, being a Quantum State generated at the moment of the appearence of local matter? The SIZE of the Graviton, dictates the 'size' of Matter, and its evolution? as the Graviton gets farther away, the matter locally is dispersing, the Energy Density of Matter fades to that of Quantum Field, until the Quantum Vacuum Equilibrium is restored, and you guessed it, there is a Graviton Burst. But there are limitations to the Quantum State?
For instance, out of an Expanding Vacuum, there are confinment limitations (close to equilibrium), the Vacuum can collapse back rather than continue in expansion. Then this can pull matter at the outer-edge of the Vacuum, backwards, thus the matter is Condensed together, without the Graviton Burst.
Einstein's early intuition of the Cosmological Constant "blunder", being a 'fixed' paramiter of Positive-out-of-Negative, rather than being "one-or-the-other"?
The Graviton in this sense is the propergator(Graviton-Burst) out of the Pure Quantum State Vacuum, prior to the Galaxy appearing. In a near perfect Equilibrated Universe state of: "Matter-Antimatter", "Positive Vacuum-Negative Vacuum" "Big-Bang Big-Crunch".
The Graviton propagated across a pure quantum field[zero-point], the Wavefunction induces the State out of Equilibrium, Galaxies "rip" out of the instabilities, all the emerging matter is 'contained' internally within this Graviton Horizon, all the Light from the Galaxies propagates along the Graviton Route, to the Cosmological Horizon. Another fluctuation out of the Quantum State Vacuum, introduces another Galaxy , dictated by it's own Cosmological Time, Graviton Horizon.
Most of the Homoogeneous energy density has negative Pressure due to the fact that over time, the "positive" Graviton, is "extracting" all positive matter that is contained "locally" close to our Galaxy. Eventually we will look into the night sky and see our "local" surrounding spacetime thinning out, the Dark will become Darker as the Light Energy fades out. The remaining E-m-V will tend to burst forth, a new phase energy out of the old phase energy?
Sakharov Induced Gravity, emerges locally from Einsteins Quantum, Graviton "Dark" Waves, polaroids included :cool:

A new paper by Stephen .D.H.Hsu and Brian.M.Murray have detailed an interesting "Graviton" phase to the initial Universe :
http://arxiv.org/abs/hep-th/0512033

where there is handwaving to the "Graviton Heatbath" as likely source of nucleation "bubbles-of-nothing"?

The facts of this is that, Blackholes are initially Gravitons, condensed out of Inflation, but they actually "expand", to contain matter within their boundaries, thus evolve from Galactic Cores, therby the Gravitational signiture of Galactic Blackholes are really anchor points(gravitational source) within a phase space that extends, but does not contain Graviton "particles", this may be why Galactic Halo's are in a sense 'Graviton-Shrouds', their evolution is dependant on the initial condition, which is horizonal dependant, because this set at the transitional unique "early" Phase?

Very interesting paper when one couples it to the Rovelli above Paper.

Another great paper that puts "information" into a precise perspective:

http://arxiv.org/abs/hep-th/0507287

and also this paper:http://arxiv.org/abs/hep-th/0512268
appears to have relevence to thread, abstract:

The most entropic fluid can be related to a dense gas of black holes that we use to study the beginning of the universe. We encounter difficulties to compatibilize an adiabatic expansion with the growing area for the coalescence of black holes. This problem may be circumvented for a quantum black hole fluid, whose classical counterpart can be described by a percolating process at the critical point. This classical regime might be related to the energy content of the current universe.

Actually there is another recent paper by Ulf Leonhardt:

http://arxiv.org/abs/cond-mat/0510071

that has an interesting correspondance with the last paper(entropic fluid) above.

One can ask why is it that in an expansive medium, such as the expanding universe, do energies contract?, energies such as matter (with respect to the expansion-field?).

If the Universe was in contraction, then Particles of matter would be getting bigger, with respect to the field?..could the Universe have evolved from an initial localized single Particle?..being that the reversed field equations that give birth to the Big-Bang model, has at its fundamental premise:The Universe is evolving from a given single location, of the size and order comprable to that of a volume , less than single atom?

In this thread by marcus:https://www.physicsforums.com/showthread.php?t=104539

he has an interesting correspondence from Smolin:
1)"why the neutron is a bit heavier than the proton"

could it be that the fact is that the Universe is in Expansion?..had the Universe been in Contracting phase, then would the Particles size be reversed?..ie would the Neutron be lighter than the Proton?
