When observing Hawking radiation, one can notice entanglement between the radiation and the interior of a black hole, indicating that information is not lost.

In principle, if one could collect all the Hawking radiation from a black hole, it would contain details about the black hole's interior, suggesting that information is not destroyed.

The black hole's interior might be quantum entangled with Hawking radiation outside, allowing for information retrieval without physically moving it from inside to outside.

The information that falls into a black hole is stored on its horizon in a way that cannot be easily reconstructed, resembling a hologram rather than a photograph.

The holographic principle suggests that the information falling into a black hole can be thought of as both falling in and being stored on its horizon.

The information paradox arises because if a particle is created just outside a black hole's event horizon, and one falls in while the other escapes, the one that falls in becomes real and cannot return to the vacuum, leading to a loss of information.

The event horizon of a black hole is a boundary beyond which nothing can escape, not even light. It's a point in spacetime that separates events that can affect an outside observer from those that cannot.

Almost all the information in the universe is in the form of black holes; they contain significantly more information than anything else.

To reconstruct the information from a black hole's horizon, one would need to shine the right kind of light on it, similar to how a hologram works, but this process is not straightforward and requires advanced technology.

When two black holes merge, they emit gravitational waves, and the final black hole's mass is less than the sum of the original black holes due to energy radiated away as gravitational waves.
