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 yet mine resources from asteroids or the Moon at a profitable scale.
open
Global / Unspecified, Global
Space contains vast amounts of metals and water that could support future industry and settlement, but the cost of extraction and transport remains far too high. Making this affordable could unlock a new resource economy beyond Earth.

We don't fully understand how the first living cells originated on Earth.
open
Global / Unspecified, Global
We know roughly when life began, but not the exact chemical steps that turned non-living matter into something that could reproduce. Solving this would also tell us where else in the universe life might arise.

We haven't figured out how to reliably protect Earth from a large asteroid impact.
open
Global / Unspecified, Global
We can now detect many dangerous asteroids years in advance, but we still lack a proven way to redirect or destroy one heading for Earth. One unlucky strike could cause damage on a civilization-ending scale.

We can't explain why matter exists at all instead of nothing.
open
Global / Unspecified, Global
According to our best theories, matter and antimatter should have destroyed each other completely after the Big Bang. Yet matter clearly won out, and we still don't know why.

We don't have an affordable way to remove dangerous debris from Earth's orbit.
open
Global / Unspecified, Global
Thousands of pieces of space junk are already circling the planet, threatening satellites and future missions. Left unresolved, orbit could become too cluttered and risky to safely launch into.

We haven't built a spacecraft that can reach nearby stars within a human lifetime.
open
Global / Unspecified, Global
Even our fastest probes would take tens of thousands of years to reach the nearest star system. Without a breakthrough in propulsion, interstellar travel remains purely theoretical.

We can't accurately forecast volcanic eruptions before they happen.
open
Global / Unspecified, Global
Some volcanoes give warning signs, but many erupt with little notice, putting nearby populations at serious risk. Better prediction could prevent mass casualties near active volcanoes worldwide.
Citation ID: WS00009
Title: We can't accurately forecast volcanic eruptions before they happen.

We don't understand why the universe's expansion is speeding up instead of slowing down.
open
Global / Unspecified, Global
Gravity should be pulling everything together over time, yet distant galaxies are accelerating away from each other. This mystery, blamed on dark energy, remains one of the biggest open questions in physics.

We can't grow food efficiently enough to support long-term human settlements off Earth.
open
Global / Unspecified, Global
Growing crops in space or on other planets means dealing with low gravity, radiation, and limited water and soil. Without solving this, any permanent settlement beyond Earth stays dependent on costly resupply missions.

We haven't found a way to shield astronauts from radiation on long space missions.
open
Global / Unspecified, Global
Outside Earth's magnetic field, cosmic radiation raises cancer risk and can damage the brain and body over time. This is one of the biggest blockers to sending humans to Mars safely.

We can't predict earthquakes with enough warning to save lives.
open
Global / Unspecified, Global
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.
