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.

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. This shapes ongoing debates about the future of mathematical certainty.

Mathematicians rely on a diverse toolkit of proof techniques suited to different problems, and whether a single unifying method could ever replace this diversity remains a genuinely open and somewhat philosophical mathematical question. This touches on the deepest structure of how mathematical knowledge is built.

If an artificial system behaves as though it's suffering or happy without any confirmed inner experience, it remains unclear whether this simulated behavior deserves any genuine moral weight. This unresolved question is becoming increasingly relevant as AI systems grow more sophisticated.

Consequentialist and deontological ethics offer fundamentally different answers, and thought experiments pitting them against each other rarely produce consensus. This tension underlies many real-world moral dilemmas.

If aesthetic judgments are purely subjective, calling any art objectively better than another becomes philosophically difficult to defend. Yet most people act as though some works are genuinely superior, not just differently liked.

Utilitarian arguments often justify this tradeoff by pointing to lives saved, while animal rights perspectives reject using sentient beings purely as means to human ends. This unresolved tension remains central to biomedical ethics.

Some philosophers argue true morality requires genuine concern for others, while others believe self-interest can align with moral behavior without undermining its validity. This unresolved question touches on the deepest motivations behind ethical action.

As artificial systems become more sophisticated, the possibility that some could genuinely suffer raises serious unresolved questions about the ethics of their creation and use. This concern will likely intensify as the technology matures.
