TL;DR
This paper identifies a loophole in existing island formation proofs, introduces the concept of island mirages that satisfy conditions but lack islands, and discusses related puzzles and resolutions.
Contribution
It reveals limitations in current island criteria, introduces the concept of island mirages, and addresses associated puzzles including a tension with the quantum Bousso bound.
Findings
Examples satisfying island conditions but lacking islands
Identification of two new puzzles related to islands
Resolution proposals for the puzzles
Abstract
We point out a loophole in the proof that the Island Finder conditions are sufficient for the existence of islands. We explore examples which satisfy the conditions, but have no islands, which we call island mirages. We also describe and give resolutions to two new puzzles associated with islands, including a direct tension with the quantum Bousso bound.
