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.

General relativity and quantum field theory conflict at extreme densities, such as inside black holes and at the Big Bang. Progress in string theory, loop quantum gravity, and holographic dualities could lead to a consistent framework.

Kepler and other missions have identified thousands of exoplanets, but we lack robust statistics on Earth-size worlds with stable climates and liquid water. Next-generation transit and direct-imaging missions must refine occurrence rates.
