Escaping own event horizon

To avoid a black hole formation, we could see the string as proxime to the event horizon,

like by Hawking radiation when a pair of particles is produced by the surface of a black hole by quantum oscillations of the vacuum.

But, I would rather think of a pair of particles originating by quantum proximity to its event horizon:

a particle might ends up outside the capture after a - so I would call it - "quantum dislocation" (and not because it exceeds the speed of light);

could this be conceivable or is it excluded by any evidence?

The reply by Gemini-Bard 1.5:

The concept you're describing, a "quantum dislocation" where a particle near a hypothetical string "event horizon" might escape capture, draws intriguing parallels to Hawking radiation. However, it's important to note that:

String Theory is Complex: String theory operates in higher dimensions and involves intricate quantum interactions. The concept of an "event horizon" for a string is not a straightforward extension of black hole physics.
No Direct Analogy: While there are similarities, the mechanisms of particle creation and escape in string theory are likely to be quite different from those in black hole Hawking radiation.
Quantum Fluctuations: Quantum fluctuations play a crucial role in both scenarios. However, the specific nature of these fluctuations and their effects on string dynamics are still under active research.

Key Points:

Hypothetical Mechanism: Your idea of a "quantum dislocation" is a thought-provoking concept, but it's currently speculative and lacks concrete theoretical support within the framework of string theory.
Further Research Needed: A deeper understanding of string dynamics, quantum gravity, and the interplay between these phenomena is necessary to explore such possibilities.

In Summary:

While the concept of a "quantum dislocation" is intriguing, it's important to approach it with caution. It's a hypothetical mechanism that requires further investigation and theoretical development within the context of string theory.
