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.

AI systems can generate false information with the same fluent, confident tone as accurate information, making it hard for users to tell the difference without independently verifying every claim. Reducing this so-called hallucination problem remains a central AI research challenge.

Modern AI models produce answers without a clear, checkable chain of reasoning, making it hard to know if a correct answer was reached for the right reasons. Verifiable reasoning is essential before AI can be trusted in high-stakes decisions.

Many rural communities have no way to verify if their drinking water is safe, leading to preventable illness. Low-cost portable water-testing kits distributed through community health workers could close this gap.

Some modern proofs rely heavily on computer verification because they're too long or complex for any person to check by hand, raising open questions about whether shorter, purely human-verifiable proofs must always exist. This unresolved tension touches both mathematics and epistemology.

Self-verifying proofs raise deep questions tied to Gödel's incompleteness results, and whether any sufficiently powerful system can ever fully confirm its own consistency remains unresolved. This continues to shape foundational debates in mathematical logic.

Some proofs span thousands of pages or rely on massive computer verification, and whether complete, error-free confidence is ever truly achievable for such proofs remains a genuinely unresolved epistemological and mathematical question.

Achieving technologies for verifying compliance with international environmental agreements 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.
