Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

The Coronal Heating Problem violates intuition: the outer solar atmosphere reaches millions of degrees while the surface is ~5,500°C. Solving this requires understanding magnetic reconnection and Alfvén wave dissipation mechanisms.
