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.
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.
The structure of neutron-star interiors is uncertain.
Their equation of state depends on poorly constrained nuclear physics at extreme densities. Multi-messenger observations of mergers and precise timing can narrow possibilities.
We do not fully understand the cosmic reionization history.
Timing and sources of reionization remain uncertain. 21cm experiments and high-z galaxy observations can map it.
Global positioning systems (like GPS) do not extend to the Moon or interplanetary space.
Navigating craft and rovers on the lunar farside or in deep space relies heavily on congested Earth ground antenna networks. Scalable lunar and deep-space autonomous navigation and timing constellations are needed.
Deep-space optical navigation loses accuracy when spacecraft travel far from recognizable stars.
Traditional star trackers struggle when solar glare or local dust plumes obstruct sensor fields during maneuvers. Pulsar-based navigation systems utilizing ultra-precise atomic X-ray timing signals are needed.
Managing glacier-fed water variability for downstream communities
Improve local forecasting, storage, allocation, and conflict-resolution systems as glacier melt changes the timing and reliability of river flows.
