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.

When the first person to capture an image of a cloud asserts property rights, the atmosphere itself becomes a contested resource. The problem is keeping the sky as a shared commons while still recognising legitimate creative or scientific claims on specific observations.

When corporations patent forms of rainwater collection or composition in water-scarce areas, ordinary puddles and runoff become potential infringement sites. The challenge is designing water-rights frameworks that protect both innovation incentives and the basic human need for free access to precipitation.

FRBs unleash as much energy in milliseconds as the Sun emits in days, yet their origins—whether magnetars or exotic energetic events—are unconfirmed. Resolving this will yield new insights into extreme astrophysics and cosmic plasma.

Measurements of the cosmic microwave background yield a lower expansion rate than direct distance ladder measurements of modern galaxies. Resolving this discrepancy could reveal brand-new physics beyond the Standard Model.

Some patients continue experiencing symptoms long after completing standard treatment for Lyme disease, and doctors disagree on both the cause and the best way to treat this lingering illness. Resolving this uncertainty remains a significant unmet need.

People without citizenship often can't access healthcare, education, legal employment, or travel documents, trapping them in a kind of legal limbo. Resolving statelessness requires cooperation between countries that often have little incentive to act.

When election results are close or contested, some countries have no clear, agreed procedure for resolving the dispute short of prolonged conflict or unrest. This leaves democratic transitions vulnerable at exactly their most sensitive moment.

The Prime Number Theorem offers an excellent approximation, but the finer details of exactly how actual prime counts deviate from this smooth prediction remain tied to the still-unproven Riemann Hypothesis. Fully resolving this would refine one of number theory's most central results.

If value is tied only to usefulness, this raises uncomfortable implications for how we treat people who can no longer contribute to society. Resolving this question remains foundational to debates on dignity and human rights.

Even acts of apparent sacrifice can be explained by psychological rewards like satisfaction or social approval, raising doubt about whether pure altruism is even possible. Resolving this affects how we understand human motivation and moral praise.

International courts and diplomacy exist, but nations still frequently settle disputes through force when other methods fail or are ignored. A stronger, more trusted system for resolving conflicts peacefully remains unbuilt.
