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 can't predict earthquakes with enough warning to save lives.
open
United States, North America
Seismologists can identify risky zones but not the exact moment a quake will strike. A few minutes of reliable warning could save thousands of lives in earthquake-prone cities.

We don't know what most of the universe's mass and energy actually are.
open
Global / Unspecified, Global
Dark matter and dark energy make up roughly ninety five percent of the universe, yet we've never directly detected either. Everything we can see and touch is a small fraction of what's really out there.

We can't yet build a fusion reactor that produces more energy than it consumes for sustained periods.
open
Global / Unspecified, Global
Fusion promises nearly limitless clean energy, but every experiment so far has needed more power to run than it generates. Cracking this would end the global energy crisis outright.

We don't have a working theory that unifies gravity with quantum mechanics.
open
Global / Unspecified, Global
Gravity describes the large scale universe well, and quantum mechanics describes the tiny scale well, but the two don't fit together mathematically. A unified theory would finally explain what happens inside black holes and at the birth of the universe.

We have never proven whether life exists anywhere beyond Earth.
open
Global / Unspecified, Global
Every search so far has come back empty, but our tools for detecting distant life are still crude. Knowing the answer would reshape biology, philosophy, and how we think about our place in the universe.
