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.

Energy, computing, medicine, and infrastructure may depend on minerals with concentrated or fragile supply chains. Research must identify substitutes without trading scarcity for toxicity, low performance, or new ecological damage. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

If machines and software generate large economic value with fewer workers, existing payroll and income tax structures may weaken. Governments need alternatives that fund public goods without punishing productive investment. The solution must produce useful coordination and accountability while minimizing collection of sensitive personal and behavioral data. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Alternative proteins may improve land efficiency but face allergen, contamination, cultural, and market barriers. Solutions must include rigorous standards and locally appropriate product development. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Modern economies rely on precise timing for finance, telecom, energy, and navigation. Future systems need resilient alternatives to single-source satellite timing during cyberattacks, solar storms, and geopolitical crises. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Future shocks may affect several producing regions simultaneously, making traditional diversification insufficient. The challenge is combining storage, alternative crops, trade rules, logistics, and social protection without creating waste or market distortion. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Claims about quantum advantage often depend on narrow benchmarks or idealized assumptions. The challenge is creating reproducible measurements that identify when quantum systems deliver meaningful benefits over classical alternatives. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Once a company achieves significant market dominance, it can sometimes reduce quality or add restrictions with little competitive consequence, since users have few comparable alternatives. Preventing this kind of unchecked degradation remains an unresolved market structure issue.

Many websites and applications are still built without full consideration for users who rely on screen readers, alternative input devices, or other accessibility tools. Making accessibility a foundational design principle rather than a later patch remains inconsistent.

Digital voting could make elections faster and more accessible, but security concerns and lack of public trust have kept most large-scale elections reliant on paper-based or hybrid systems. A truly trusted digital alternative remains unbuilt.

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.
