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.

General relativity and quantum field theory conflict at extreme densities, such as inside black holes and at the Big Bang. Progress in string theory, loop quantum gravity, and holographic dualities could lead to a consistent framework.

Current models rely on limited spectra from a small subset of planets, often with degeneracies in composition and cloud structure. High-resolution time-resolved spectroscopy and improved atmospheric retrieval algorithms are needed.

Kepler and other missions have identified thousands of exoplanets, but we lack robust statistics on Earth-size worlds with stable climates and liquid water. Next-generation transit and direct-imaging missions must refine occurrence rates.

These millisecond bursts of radio energy come from cosmological distances, but their progenitors are uncertain, ranging from magnetars to exotic compact objects. Coordinated multi-wavelength observations and rapid follow-up networks could identify their sources.
