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 whether every even number greater than two is the sum of two primes.
open
Global / Unspecified, Global
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.

We don't have a complete theory predicting how prime numbers are distributed.
open
Global / Unspecified, Global
Prime numbers appear to follow patterns at large scales but seem random up close, and mathematicians still lack a full explanation for this behavior. Understanding it better could improve encryption methods that rely on primes.

We haven't proven the Riemann Hypothesis, a problem central to understanding prime numbers.
open
Global / Unspecified, Global
This century-old conjecture predicts a hidden pattern in how prime numbers are distributed, but nobody has ever proven it true. A proof would deepen our understanding of numbers in ways that ripple into cryptography and physics.

We still don't know whether every math problem that's easy to check is also easy to solve.
open
Global / Unspecified, Global
Known as the P versus NP problem, this asks whether problems whose solutions are easy to verify are also easy to find in the first place. Answering it would reshape computer science, cryptography, and optimization overnight.
