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.

Large mega-constellations reflect sunlight and emit spurious radio frequencies, interfering with ground-based optical and radio telescopes. Low-reflectivity coatings, active satellite beam steering, and mitigation software are needed.
