World Solve — A living repository of problems worth solving.

What World Solve is

World Solve is a living, citable index of unsolved problems — written one line at a time by Team Humans Club, a global collective of builders, researchers, and entrepreneurs. We do not solve the problems here. We Democratize Innovation.

For builders Skip the search for a problem worth your time. Browse a vetted, growing list and start where the gap is real.

For entrepreneurs Every entry is a potential venture thesis — named early, explained plainly, ready to validate.

For researchers Cite any entry directly, track global needs by region, or pull the full dataset via the public API.

We haven't solved how to preserve oral histories and traditions before the last speakers or keepers pass away.

open Global / Unspecified, Global

Much of humanity's cultural knowledge lives only in memory, passed down verbally, and disappears permanently when the last person who remembers it dies. Systematic preservation efforts remain underfunded and incomplete.

We haven't proven a rigorous, complete theory explaining turbulence in fluids mathematically.

open Global / Unspecified, Global

Turbulent flow, like water rushing through a pipe or air moving over a wing, is notoriously hard to describe with exact mathematics. A complete theory would improve everything from weather prediction to aircraft design.

We don't have a general formula predicting exactly how many prime numbers exist below any given number.

open Global / Unspecified, Global

We have very good approximations, but no exact formula exists that perfectly predicts the count of primes below a chosen number. Improving this approximation remains an active and important area of research.

We haven't settled whether every sufficiently large even number can always be written as the sum of two prime numbers.

open Global / Unspecified, Global

This idea, part of an old and famous conjecture, has held true in every case checked so far but has never been proven true for all numbers without exception.

We don't have a complete solution to the traveling salesman problem for very large numbers of locations.

open Global / Unspecified, Global

Finding the shortest possible route visiting a long list of locations becomes exponentially harder as the list grows, and no fully efficient general solution exists. Logistics, chip design, and delivery networks all run into this limit.

We haven't proven whether there are infinitely many twin prime numbers.

open Global / Unspecified, Global

Twin primes are pairs of prime numbers that differ by only two, and mathematicians strongly suspect there are infinitely many, but nobody has proven it. This remains one of number theory's oldest open questions.

We haven't settled what obligations, if any, humans have toward preserving species that provide no direct benefit to people.

open Global / Unspecified, Global

Conservation efforts often focus on species useful or appealing to humans, leaving the ethical status of less charismatic species less clear. Whether all species deserve equal protection regardless of usefulness remains unresolved.

We don't agree on whether nations have a moral duty to accept refugees beyond what international law requires.

International law sets minimum obligations toward refugees, but whether wealthier nations have a deeper moral duty beyond the legal minimum remains a genuinely contested ethical question.

We haven't settled whether it's ethical to allow markets to exist for things like human organs or surrogate pregnancies.

We haven't found a universal answer to how societies should balance individual merit against equal opportunity.

open Global / Unspecified, Global

Some believe rewards should go strictly to those who work hardest or perform best, while others argue unequal starting points make pure merit-based systems inherently unfair. This tension remains philosophically unresolved.

We don't agree on whether it's ethical to bring back extinct species using genetic technology.

Reviving extinct species raises questions about ecological impact, animal welfare, and whether it's truly meant to help nature or satisfy human curiosity. There's no consensus on whether this is a responsible use of the technology.
