Fuzzball

"The fuzzball construction resolves the black hole information paradox by making spacetime end
just before the horizon is reached. But if there is no traditional horizon, then do we lose the elegant
relations of black hole thermodynamics? Using an argument similar to modular invariance, we argue
that the answer is no; the completeness of fuzzball states implies that the generic fuzzball indeed
reproduces the thermal properties attributed to the traditional hole"...

... Nicely done except for my allergies on extra dimensions IMO. Space-time itself ends just before what looks like the event horizon. Using a bit of imagination. It looks like a BH (outside observer).

Planck star

"A star that collapses gravitationally can reach a further stage of its life, where quantum-gravitational pressure counteracts weight. The duration of this stage is very short in the star proper time, yielding a bounce, but extremely long seen from the outside, because of the huge gravitational time dilation. Since the onset of quantum-gravitational effects is governed by energy density --not by size-- the star can be much larger than Planckian in this phase."

... Very easy to get by even if the BOUNCE is unconventional (Bounce exceeds the speed of light).

Final state boundary condition at the black hole singularity.

"This proposal naturally resolves the black hole information puzzle in the following way.
In the process of black hole evaporation, particles are created in correlated pairs with one
falling into the black hole and the other radiated to in¯nity. The correlations remain even
when the particles are widely separated. The ¯nal state boundary condition at the black
hole singularity acts like a measurement that collapses the state into one associated with
the infalling matter. This transfers the information to the outgoing Hawking radiation in
a process similar to \quantum teleportation".

"They're proposing that particles escaping from the event horizon can gather the information that's flowing back outwards almost instantly and carry it away. But... an observer falling in could notice the time shift when they entered the black hole, violating relativity.

Our proposal is clearly very speculative, and we have not given any constructive method
for computing the black hole final state."

Ice wall?

The quantum link forces particles near the wormhole's horizon into a particular quantum state, "freezing" them and giving away the horizon's location. "It's like having a signpost at the horizon, which is one thing we're not allowed to do," says Bousso.

Any insight guys!

I find these proposals fascinating and thought-provoking. The idea of a "fuzzball" or "planck star" as a resolution to the black hole information paradox challenges our current understanding of black holes and their behavior. The concept of a final state boundary condition at the singularity also raises interesting questions about the nature of information and how it is transferred in quantum systems.

Furthermore, the idea of a quantum link at the wormhole's horizon and the possibility of an "ice wall" at the horizon also presents new avenues for exploration in understanding the behavior of black holes and their interactions with matter.

However, as the authors themselves acknowledge, these proposals are still highly speculative and require further research and testing to fully understand their implications. As scientists, it is important to approach these ideas with an open mind and continue to explore and test them through rigorous experimentation and observation. Only then can we truly gain a deeper understanding of the mysteries of black holes and their role in the universe.
 

FAQ: Competing model on Firewall Paradox

1. What is the "Firewall Paradox" in the context of competing models?

The Firewall Paradox is a theoretical problem in the field of network security, specifically in the analysis of firewall policies. It refers to the situation where two or more competing models of a firewall policy both claim to be the most secure, but they contradict each other and cannot be applied simultaneously.

2. How does the Firewall Paradox occur?

The Firewall Paradox arises when different models of a firewall policy are designed to achieve the same goal, such as restricting access to a particular network, but use different rules or methods to achieve that goal. This can result in contradictory rules that make it impossible to implement all of the models at the same time.

3. What are the consequences of the Firewall Paradox?

The Firewall Paradox can have serious consequences for network security. It can lead to confusion and errors in policy implementation, as well as potential vulnerabilities that can compromise the security of the network. It can also make it difficult for network administrators to determine which model is the most effective or secure.

4. How can the Firewall Paradox be resolved?

One approach to resolving the Firewall Paradox is to identify the underlying assumptions and principles of each competing model and find a compromise or common ground between them. This could involve modifying the models or creating a new, unified model that incorporates the strengths of each individual model.

5. What are some potential solutions to prevent the Firewall Paradox?

To prevent the Firewall Paradox from occurring, it is important for network security professionals to carefully consider the design and implementation of firewall policies. This could involve using standardized models or methods, as well as regularly reviewing and updating policies to ensure they are consistent and effective. Additionally, implementing multiple layers of security, such as a combination of firewalls and intrusion detection systems, can help mitigate the impact of the Firewall Paradox.
