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.

Indirect gravitational measurements confirm dark matter's existence, but direct detection experiments have failed to identify the constituent particle. Solving this is necessary to complete our fundamental model of physics.

Astronauts lose up to 1-2% of bone mass per month in microgravity despite daily intensive physical exercise regimes. Artificial gravity habitats or gene-targeted therapeutics are needed to enable multi-year interstellar trips.

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.

Chronic malnutrition in early childhood can cause lasting physical and cognitive effects that are difficult to reverse later in life. Preventing this before it happens remains far more effective, and far less solved, than treating it afterward.
