• Event Horizon: Surrounding the singularity is the event horizon, a point of no return. Light rays cannot escape beyond this point due to the immense gravity.
• Cauchy Horizon: Before reaching the event horizon, there’s a theoretical boundary called the Cauchy horizon. Once past this point, no information or signals, including light, can travel outward to an observer.

Self-Portrait:

• Impossible View: Due to the nature of black holes, creating a self-portrait from within one is impossible. Any light attempting to capture your image would be pulled inwards by the gravity, never to escape and reach an observer outside.
• Distorted View from Outside: An observer outside the black hole might see a distorted and stretched image of you falling towards the event horizon, due to the warping of spacetime by the black hole’s gravity. The image would eventually fade away as you cross the event horizon.

2. White Hole (Hypothetical): A One-Way Exit

Light and Perspective:

• Singularity: Similar to a black hole, a white hole is theorized to have a singularity at its core. However, unlike a black hole, the singularity in a white hole is a point of origin, not collapse.
• Event Horizon: A white hole is predicted to have an event horizon as well, but with the opposite effect. Light rays and matter can escape from within the white hole but cannot enter it.
• Unknown Beyond: As white holes are purely theoretical, the behavior of light and matter beyond the event horizon is unknown.

Self-Portrait:

• Limited View: Since nothing can enter a white hole, creating a self-portrait from within is not possible.
• External View: An observer outside the white hole wouldn’t be able to see anything going in. They might perceive a sudden burst of radiation or energy erupting from the white hole’s event horizon, but wouldn’t be able to see anything inside.

In Conclusion:

While the concepts of black holes and white holes are fascinating, they represent extreme environments beyond our current ability to directly observe or experience them. However, they continue to inspire scientific inquiry and speculation about the nature of our universe.
