When the photon is born on the horizon .bang?

In summary, the conversation discusses the behavior of a photon born on the horizon of a black hole and what happens to it if it has a perpendicular speed at the time of its birth. It is concluded that a photon can escape if it is strictly at or outside the event horizon, but if it is on the horizon, it can only stay on the horizon.

when the photon is born on the horizon...bang?

2 electrons are traveling around a black hole, after some time they meet themselves exactly at the horizon of the hole, generating a photon.

if for fate the particle at the moment of be born has a perpendicular speed (opposed relative the center of the black hole), what happends to the photon?

i'm not sure it falls down neither escape, if we suppose it to be at the matematical confine of the horizon , but it must anyway maintain his c speed...:bugeye:

A photon strictly at or outside the event horizon can escape; a photon inside the event horizon cannot.

No, the event horizon is a null hypersurface, so, if a photon is on the horizon, the best that it can do (in terms of "escaping") is to stay on the horizon.

FAQ: When the photon is born on the horizon .bang?

What is the horizon "bang" phenomenon and why is it important in physics?

The horizon "bang" phenomenon refers to the moment when a photon (a particle of light) is created on the event horizon of a black hole. This event is significant in physics because it challenges our understanding of the laws of physics, specifically the theory of relativity.

How does the creation of a photon on the horizon affect the black hole's properties?

The creation of a photon on the horizon does not significantly alter the black hole's properties. However, it does contribute to the black hole's mass and can potentially lead to the creation of a new black hole if enough photons are created.

Can we observe the creation of a photon on the horizon?

No, we cannot directly observe the creation of a photon on the horizon as it occurs beyond the event horizon, which is the point of no return for anything entering a black hole. However, we can indirectly observe its effects, such as the emission of Hawking radiation.

How does the horizon "bang" phenomenon relate to the theory of relativity?

The horizon "bang" phenomenon challenges the theory of relativity as it suggests that the laws of physics, specifically the conservation of energy, may not hold true at the event horizon of a black hole. This implies that our understanding of gravity and spacetime may need to be revised.

Are there any potential applications of studying the horizon "bang" phenomenon?

Studying the horizon "bang" phenomenon can help us gain a deeper understanding of the fundamental laws of physics, including the theory of relativity. It may also have implications for technologies such as black hole detectors and space travel. However, further research is needed to fully explore its potential applications.
