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.

Hurricanes and tornadoes can still shift path or intensity with little warning, leaving communities scrambling to evacuate. More precise, longer-range forecasting could save lives and billions in property damage every year.

Neuroscience can map which brain regions activate during thought, but nobody can explain why that activity produces subjective experience at all. This gap separates our understanding of the brain from any real understanding of the mind.

Growing crops in space or on other planets means dealing with low gravity, radiation, and limited water and soil. Without solving this, any permanent settlement beyond Earth stays dependent on costly resupply missions.

Gravity describes the large scale universe well, and quantum mechanics describes the tiny scale well, but the two don't fit together mathematically. A unified theory would finally explain what happens inside black holes and at the birth of the universe.
