World Solve

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 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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
