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.

Spoken dialogue that produces persistent aerial annotations can create distraction, privacy leaks, and unequal access to context. The problem is managing real-time annotation layers so they remain optional and controllable by speakers.

Entrances that expand or contract according to digital invitation data can exclude people with disabilities or create real-time social filtering. The challenge is keeping physical thresholds inclusive regardless of digital status signals.

sports facilities closed to many communities remains one of the most urgent challenges of our time. Systems currently in place are inadequate for the scale and complexity of the problem. A successful approach must work where resources are scarcest and demonstrate clear, measurable results. It should identify possible harms, respect local agency, and show how the solution can be maintained and expanded by the communities it is meant to serve.

Social bonds structured as time-limited agreements with automatic termination notices can undermine trust and long-term support networks. The problem is allowing intentional relationship boundaries without making every connection provisional and transactional.

Clocks that accelerate or slow according to local output targets fracture shared temporal reference. The challenge is maintaining a common civic time base while still allowing local performance incentives.

If parks close at night on the grounds that vegetation requires solitude, human access to green space is reduced. The problem is integrating genuine ecological rest requirements with the continuous human need for outdoor refuge and recreation.

Roadways that shrink in real time based on predicted density can trap pedestrians and restrict access. The problem is managing crowd flow without creating physical bottlenecks that endanger people or exclude those with mobility needs.

Statues that continuously change expression or posture according to live public sentiment risk turning monuments into unstable opinion mirrors. The problem is allowing cultural responsiveness without erasing the original historical record or creating permanent contention over every figure.
