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.

Astronomical observations demand extra unseen mass, but candidate particles from extensions of the Standard Model remain undetected. New detector designs, astrophysical surveys, and theoretical models are needed to pin down its nature.

Cosmological data show the Universe’s expansion speeding up, yet we lack a clear physical mechanism beyond a simple cosmological constant. Precision surveys and alternative gravity theories could clarify whether dark energy is a new field or modified gravity.

Big Bang models suggest equal amounts of matter and antimatter, yet the observable Universe is dominated by matter. Precision measurements of CP violation and new physics at high energies could explain the imbalance.
