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 do not know the long-term biological effects of fractional gravity on plant growth and seed viability.

open Global / Unspecified, Global

While microgravity (0g) is well-studied, long-term multi-generational plant reproduction under lunar (0.16g) or Martian (0.38g) gravity is unverified. Long-term surface greenhouse experiments are urgently needed.

We lack an operational planetary defense mechanism to deflect large, fast-moving interstellar objects like 'Oumuamua.

open Global / Unspecified, Global

Objects originating from outside our solar system pass through at extreme hyperbolic velocities with minimal discovery lead-time. High-delta-v interceptor platforms on standby in deep space orbits are required for defense.

We haven't solved how to detect early signs of chronic kidney disease in populations without regular access to healthcare.

open Global / Unspecified, Global

Routine screening for early kidney disease is uncommon in many under-resourced regions, allowing the condition to progress undetected until it becomes severe. Expanding accessible, affordable screening remains an unresolved global health priority.

We don't have an effective way to treat chronic dry mouth caused by certain long-term medications.

We can't yet fully explain why some patients experience chronic complications from strep throat despite prompt treatment.

Even when strep throat is treated quickly with antibiotics, a small number of patients go on to develop complications like rheumatic fever. Understanding why prompt treatment doesn't always prevent this remains an open medical question.
