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.

The boom in commercial satellite constellations on Earth causes RF noise that bleeds into planetary science frequency bands. Strict international spectrum carving and transition to optical laser links are necessary.

While optical communication offers high bandwidth, cloud cover blocks laser signals from deep space probes to Earth ground stations. Dynamically routed global ground-station networks and satellite relays are needed.

False information about disaster response, shelters, or aid can spread rapidly during emergencies, sometimes putting lives at further risk. Faster, trusted communication channels during crises remain underdeveloped in many regions.

Information theory provides strong bounds on efficiency for many specific cases, but proving whether truly optimal encoding always exists for every possible scenario remains an unresolved theoretical question. This connects mathematics directly to modern data compression and communication.

Underwater noise from ships can interfere with the way whales and other marine mammals communicate and navigate, and mitigation measures remain inconsistently enforced across major shipping routes. Reducing this impact remains an underaddressed conservation issue.

Fraudulent insurance solicitations using AI-generated communication can convincingly mimic legitimate agents, leading victims to pay for coverage that doesn't actually exist. Detecting and shutting down these operations quickly remains an unresolved consumer protection challenge.

Fraudulent recall notices, generated to appear official, could mislead consumers into either unnecessary returns or ignoring genuine safety recalls entirely. Verifying the authenticity of recall communications quickly remains an unresolved consumer safety issue.

Machine translation is fast and often accurate, but it still misses jokes, idioms, and cultural context that change meaning entirely. Real cross-cultural communication needs more than word-for-word accuracy.

Develop offline-capable, multilingual, trusted systems for issuing alerts, gathering local conditions, and coordinating response when normal communications fail. The challenge is especially acute in informal settlements, where existing solutions often assume stable institutions, high incomes, continuous connectivity, or centralized service delivery.
