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.

Future cities may depend on private platforms operating transit, energy, housing, communication, and public-space services. Strong public-interest rules are needed when essential services are controlled through private systems. 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 missions beyond low Earth orbit will expose crews to radiation, isolation, altered gravity, communication delays, and limited emergency care. The open problem is developing autonomous health systems that remain safe under unknown conditions. 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.

Spoken words may leave lasting sonic residues audible only to selected listeners, creating hidden layers of communication and potential surveillance. The challenge is controlling persistence, access, and erasure of these echoes so they do not undermine privacy or create invisible social hierarchies.

When companion animals gain the ability to express complex preferences and demands, existing ownership models break down. The problem is defining rights, responsibilities, and welfare standards that protect both animals and humans without creating unmanageable legal or social burdens.

Rapid language change driven by neural interfaces may make ordinary conversation between grandparents and grandchildren impossible without permanent translation layers. The problem is preserving mutual understanding and cultural continuity without forcing everyone onto the same implant standard or erasing linguistic diversity.

Severe solar storms can disrupt satellites, power grids, navigation, aviation, and communication networks. Future resilience requires better forecasting, hardened systems, coordinated shutdown procedures, and affordable protection for developing countries. Affected communities must have meaningful control over data, revenue, deployment decisions, and the right to refuse harmful applications. 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 quantum networks will need coexistence with conventional fiber, satellites, and noisy metropolitan infrastructure. A major unresolved problem is developing practical repeaters, interfaces, standards, and operational security for real-world deployment. 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.

Private companies may increasingly run water, transport, energy, communication, and housing systems with public consequences. The open problem is designing regulation that ensures reliability, accountability, and public recourse when essential services fail. The challenge is especially acute in informal settlements, where legacy systems, coordination failures, and weak oversight can magnify harm.

Future organizations may use teams of specialized agents that negotiate, delegate, verify, and act across software and physical systems. It remains difficult to guarantee that local objectives, hidden incentives, and communication errors do not produce unsafe collective behavior. 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.

A system can be factually sophisticated yet dangerous when users cannot distinguish knowledge, inference, speculation, and fabrication. The challenge is creating interfaces and evaluation standards that communicate uncertainty in ways people actually understand and use. 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.

Political communication will increasingly include deepfakes, voice cloning, and AI-generated persuasion at scale. The challenge is developing election rules, platform standards, and enforcement systems that protect speech while limiting manipulation. The challenge is especially acute in informal settlements, where legacy systems, coordination failures, and weak oversight can magnify harm.

AI can now craft phishing emails with perfect grammar and highly personalized context that closely mimic real business correspondence, making them far harder for both people and filters to catch. Staying ahead of this improving deception remains an unresolved challenge.
