World Solve

Automated trading algorithms can sometimes trigger rapid, extreme price swings in smaller or less liquid markets, especially during unusual conditions, without any single actor intending market harm. Building safeguards against this kind of systemic risk remains incomplete.

Even advanced AI systems can confidently state things that violate obvious physical logic, like objects falling upward or liquids not filling containers. This gap shows current AI still lacks a genuine model of how the physical world works.

Kepler and other missions have identified thousands of exoplanets, but we lack robust statistics on Earth-size worlds with stable climates and liquid water. Next-generation transit and direct-imaging missions must refine occurrence rates.

Few companies list on local stock exchanges, limiting options for businesses to raise growth capital domestically. Regional stock exchange integration could deepen liquidity and attract more investors.

Hydrogen and oxygen boil off due to solar radiation in orbit, prohibiting long-duration storage for deep space stages. Advanced active cryocooling, sunshields, and zero-boil-off insulation technologies are required.

These moons host liquid water oceans under miles of ice, warmed by tidal forces, but we lack robotic tools capable of melting through kilometers of crust to sample liquid water without introducing Earth contamination.

Sterilization requirements to avoid contaminating Mars with Earth microbes make landers exceptionally expensive and slow to build. Advanced bio-decontamination standards and rapid cleanroom testing methods are required.

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.

Multiple competing microfinance institutions operating in rural districts frequently over-indebt low-income borrowers, forcing families to liquidate essential assets or migrate to repay interest rather than building sustainable livelihoods.

Artisanal gold miners use liquid mercury to extract gold, discharging toxic heavy metals into river systems and causing severe neurological damage.

Evidence suggests Mars once had liquid water, a key ingredient for life, but no mission has yet found conclusive proof of past or present microbes. Answering this remains one of planetary science's biggest open questions.

Some outer moons hide liquid oceans beneath thick ice, and possibly conditions that could support life. Getting real data from beneath that ice remains a major unsolved engineering and mission challenge.

Achieving materials enabling efficient direct conversion of sunlight to liquid fuels at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.
