World Solve

Automated scheduling, evaluation, pricing, and dismissal may shape work without a visible manager. The unresolved problem is giving workers collective voice over systems that are proprietary, dynamic, and difficult to audit. 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.

Individualised audio environments inside shared lifts can isolate passengers and prevent common situational awareness. The problem is balancing personal comfort with the need for collective auditory cues in confined public spaces.

Lifts that prioritise or restrict floors according to behavioural scores create physical segregation inside buildings. The problem is designing vertical mobility that remains accessible and non-discriminatory regardless of any scoring system in use.

Biological data repositories growing in public or private trees raise questions of ownership, access, and longevity. The problem is ensuring that information rooted in living organisms remains under the control of the original subject and does not become harvestable by third parties.

Solar panels contain valuable and sometimes hazardous materials that current recycling processes struggle to recover efficiently and cheaply. As the first generation of panels ages out, this waste problem is becoming more urgent.

General relativity and quantum field theory conflict at extreme densities, such as inside black holes and at the Big Bang. Progress in string theory, loop quantum gravity, and holographic dualities could lead to a consistent framework.

Many households still burn solid fuels indoors for cooking and heating, causing significant respiratory illness, especially among women and children. Clean cookstove distribution programs need continued scaling and subsidy support.

Atmospheric pressure and temperatures inside gas giants destroy probes long before reaching their cores. Advanced gravitational mapping, seismic sensors, and neutrino probes are needed to uncover their core states.

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.

Without gravity, liquid fuels float randomly inside tanks, causing air bubbles to enter fuel pumps during orbital refilling. Scalable fluid-settling systems and bladderless zero-g fuel transfer ports must be built.

Enormous amounts of human knowledge and art remain physically locked inside buildings that most of the world's population will never get to visit in person. Making this content genuinely accessible remotely remains incomplete.

People who expose wrongdoing inside powerful organizations often face serious professional or legal retaliation, discouraging future disclosures. Protection laws vary widely and are often weakly enforced even where they exist.

Earth's magnetic field protects us from solar radiation, but the dynamo process that generates it deep underground is still only partly understood. This matters for predicting how long that protection will last.

We understand the general physics of dying stars, but the precise trigger moment inside a collapsing star remains difficult to observe and model. Solving this would sharpen predictions about stellar life cycles across the universe.

GPS doesn't work well inside buildings, and alternative indoor positioning technologies haven't achieved the same reliability and ease of deployment needed for widespread augmented reality navigation use. Solving indoor positioning at scale remains unresolved.

The metals inside batteries and electronics are difficult and expensive to recover once a device is thrown away, so most end up in landfills instead of being reused. Cheaper recycling would ease both supply shortages and environmental damage.

Old phones, laptops, and batteries pile up in landfills, leaking toxic materials while valuable metals inside go to waste. A cheap, safe recycling process could turn a growing pollution problem into a resource stream.

Gravity describes the large scale universe well, and quantum mechanics describes the tiny scale well, but the two don't fit together mathematically. A unified theory would finally explain what happens inside black holes and at the birth of the universe.
