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.

Many users experience nausea, eye strain, or disorientation after even moderate use of virtual reality headsets, a problem that hasn't been fully solved despite years of hardware improvements. This limits how widely VR can be adopted for work or daily use.

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.

Many smart home and industrial devices ship with weak security because manufacturers prioritize low cost over protection, creating easy targets for hackers. Fixing this at scale requires an industry-wide shift that hasn't happened yet.

Qubits are extremely sensitive to their environment and lose their quantum state within fractions of a second, limiting what any quantum computer can currently do. Solving this instability is the main barrier between quantum computing's promise and its practical use.

Cosmological data show the Universe’s expansion speeding up, yet we lack a clear physical mechanism beyond a simple cosmological constant. Precision surveys and alternative gravity theories could clarify whether dark energy is a new field or modified gravity.
