Rural electrification lags urban areas by decades in most African countries.
Utilities prioritize dense, profitable urban grids, leaving villages in the dark. Community-owned mini-grid cooperatives offer a scalable rural alternative.
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.

Indirect gravitational measurements confirm dark matter's existence, but direct detection experiments have failed to identify the constituent particle. Solving this is necessary to complete our fundamental model of physics.
Dark energy accounts for roughly 68% of the universe, yet its equation of state and microscopic nature remain complete mysteries. Precise mapping of cosmic expansion over time is crucial for predicting the ultimate fate of space-time.
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.
A host star is millions to billions of times brighter than a reflecting planet, blinding optical telescopes. Next-generation space interferometers and giant optical starshades are required to resolve exoplanet oceans and continents.
Observations show massive black holes existing just a few hundred million years after the Big Bang, far too fast for standard accretion models. Direct collapse seed theories or primordial black hole physics need verification.
Lava tubes offer natural radiation shielding for habitats, but traditional wheeled rovers cannot enter steep vertical entrances. Tethered, legged, or flying drone swarms designed for dark micro-gravity caves are needed.
Matter inside neutron stars is crushed beyond atomic densities into unknown states like quark-gluon plasma. Multi-messenger astronomy combining X-ray observatories and gravitational wave detectors is needed to probe these conditions.
Solar glare blinds optical ground survey telescopes, leaving blind spots where dangerous asteroids can approach unnoticed. Space-based infrared observatories placed at Lagrange point L1 are required for solar-side scanning.
Cosmic strings are theoretical linear defects in space-time that could explain early cosmic structure formation. Advanced gravitational lensing networks are required to detect their unique space-bending signatures.
Detecting gravitational waves was a breakthrough, but modeling exactly what happens during these violent mergers pushes our computing power and physics equations to their limits.
This mismatch is part of the evidence for dark matter, but the details of how it shapes galaxy rotation are still not fully worked out. A better model would sharpen our understanding of galaxy formation.
Video calls in poorly lit rooms often still look grainy or dark despite software attempts to compensate, particularly on lower-end hardware. Better real-time image enhancement without expensive hardware remains an unresolved challenge.
Gravity should be pulling everything together over time, yet distant galaxies are accelerating away from each other. This mystery, blamed on dark energy, remains one of the biggest open questions in physics.
Dark matter and dark energy make up roughly ninety five percent of the universe, yet we've never directly detected either. Everything we can see and touch is a small fraction of what's really out there.
