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.

Hydrogen and oxygen boil off due to solar radiation in orbit, prohibiting long-duration storage for deep space stages. Advanced active cryocooling, sunshields, and zero-boil-off insulation technologies are required.

FRBs unleash as much energy in milliseconds as the Sun emits in days, yet their origins—whether magnetars or exotic energetic events—are unconfirmed. Resolving this will yield new insights into extreme astrophysics and cosmic plasma.

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.

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.

Solar glare blinds optical ground survey telescopes, leaving blind spots where dangerous asteroids can approach unnoticed. Space-based infrared observatories placed at Lagrange point L1 are required for solar-side scanning.

Achieving materials enabling efficient direct conversion of sunlight to liquid fuels at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.
