There are two goddesses, Entanglia and Vidualia.
They both read human papers from the divine world.
Entanglia
Vidualia, look at this interesting paper I found.
Vidualia
Oh, what is it about?
Entanglia
It's about black hole complementarity.
Vidualia
Black hole complementarity? What does that mean?
Entanglia
Well, it's a label attached to a set of ideas that emerged in response to the black hole information paradox.
Vidualia
What's the black hole information paradox?
Entanglia
It's a tension within quantum mechanical treatments of black holes. It suggests that something goes wrong when treating a black hole as a quantum statistical object and also considering the physics near the horizon using quantum field theory.
Vidualia
So, black hole complementarity aims to resolve this paradox?
Entanglia
Yes, exactly! It argues that the inconsistency identified by the information paradox does not create a physically or empirically relevant inconsistency.
Vidualia
That's fascinating! What are the principles of black hole complementarity?
Entanglia
There are two principles: operational complementarity and descriptive complementarity. The operational principle states that experiments conducted near an evaporating black hole will always be consistent with quantum mechanics, as long as these experiments cannot probe physics beyond the Planck scale.
Vidualia
Hmm, I think I understand. What about the descriptive principle?
Entanglia
The descriptive principle leans towards a philosophical perspective called scientific realism. It suggests that the description of the physics of an evaporating black hole should remain consistent.
Vidualia
So, if someone resists instrumentalism, they would adopt the descriptive principle?
Entanglia
Exactly! The choice depends on one's philosophical stance.
Vidualia
I see. Humans will be able to understand and apply these concepts in the future, right?
Entanglia
It's possible, but we can't say for sure. It takes time and effort to fully grasp the quantum world.
Vidualia
Maybe one day, humans will be able to explore the mysteries of black holes through black hole complementarity.
Entanglia
That's a wonderful thought, Vidualia. The quantum world holds so many possibilities.
The two goddesses continued their exploration of the human papers, hoping for a day when humans would unravel the secrets of the quantum world.
Vidualia
I got the idea for the poem from that paper.

Silent mountain whispers,

A cosmic dance, divine,

Where time and space entangle,

In celestial enshrine.

Black hole's eerie maw,

Swallowing light and lore,

Yet vastness holds a secret,

Mount Olympus, at its core.
