World Solve

Charging speed and battery performance for electric vehicles can be significantly affected by extreme temperatures, creating inconsistent experiences depending on climate. Solving this reliability gap remains an unresolved engineering challenge.

Most human knowledge lives in systems vulnerable to disaster, conflict, or simple neglect, with no single resilient backup for civilization's collective information. A well-protected global archive could safeguard this against permanent loss.

Some compression methods shrink files perfectly for certain data but fail badly on others, and no universal, lossless method works equally well for everything. Solving this could make data storage and transmission dramatically more efficient.

Classical logic struggles with situations involving incomplete information or conflicting evidence, both common in the real world. A more flexible logical system could improve everything from AI reasoning to legal decision-making.

Known as Goldbach's Conjecture, this simple-sounding statement has been checked for enormous numbers without exception, but never formally proven true for all numbers. It remains one of the oldest unsolved problems in mathematics.

Free expression is valued almost everywhere, but so is protection from harassment, incitement, and harmful misinformation, and these values often conflict directly. No universal line exists for where one right ends and the other begins.

As AI systems become more capable, questions about whether they deserve any form of moral consideration are becoming less theoretical. Society has no shared answer for where, if anywhere, that line should be drawn.

When automation replaces jobs, the resulting profits mostly go to business owners and shareholders, not the workers who lost their income. A fairer system for sharing these gains remains an unsolved economic and political question.

New industries, especially in tech, often end up dominated by one or two giant companies before regulation catches up. This can shut out competition and innovation before it even has a chance to grow.

Fewer working-age people are supporting more retirees in many countries, straining pension systems built for a different population balance. Without reform, current retirement systems risk running out of money for future retirees.

Most democratic input happens only at the ballot box, leaving years between elections where citizens have little formal say in major decisions. Better tools for ongoing public input could make governance more responsive.

Independent journalism is being restricted or shut down in many parts of the world, cutting off citizens from reliable information about their own governments. Protecting press freedom remains an unresolved struggle in much of the world.

Foreign actors have repeatedly used social media and cyberattacks to influence elections in other countries, and defenses remain reactive rather than preventive. Protecting democratic processes requires staying ahead of these tactics, not catching up after the fact.

False information often reaches millions of people before any correction catches up, and by then the damage to public understanding is already done. Fixing this gap is critical to informed public debate.

Chronic stress physically changes the brain and body over time, and we don't yet have treatments that fully reverse that damage. Understanding this could transform how we treat burnout, trauma, and related illness.

Once the spinal cord is severely damaged, current medicine offers little hope of restoring movement. Advances in nerve regeneration and brain-computer interfaces are promising but not yet a real cure.

Sustainable aviation fuel and electric planes exist in early forms but remain far more expensive than traditional jet fuel. Making clean flying both effective and affordable is still an open engineering and economic problem.

As AI-generated accounts and bots flood social platforms, telling a real person from an automated one is getting harder. Without a trusted verification method, online trust and public discourse both suffer.

Hard drives fail, file formats become unreadable, and even cloud storage depends on companies staying in business. Without a truly long-lasting storage method, much of today's digital history may simply vanish.

Billions of people still lack reliable, affordable internet, cutting them off from education, healthcare information, and economic opportunity. Closing this gap remains a matter of infrastructure cost, not lack of demand.
