Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

The Fermi paradox highlights tension between estimated probabilities and the lack of detected signals. Systematic, wide-band SETI and technosignature searches are needed.

Galaxies stop forming stars due to feedback and environment, but mechanisms vary. Surveys across environments and redshifts can clarify.

Understanding how life originally formed from non-living chemicals informs where to look for life across the galaxy. Laboratory synthetic prebiotic chemistry and planetary sample analyses are required to settle this debate.

This mismatch is part of the evidence for dark matter, but the details of how it shapes galaxy rotation are still not fully worked out. A better model would sharpen our understanding of galaxy formation.

We've confirmed thousands of exoplanets, but identifying which ones could truly support life requires data we mostly don't have yet. A clearer count would refocus the search for life beyond Earth.
