Scientific overview

What is dark matter?

Dark matter is a still-unidentified form of matter inferred from gravity. It does not emit, absorb, or reflect light in the way normal matter does, so astronomers map it indirectly by studying how it affects visible matter and light.

~85% Estimated share of all matter in the universe.

~27% Approximate share of the total mass-energy budget.

No light Mapped through gravity rather than direct radiation.

Galaxy rotation suggests extra mass

Stars and gas in many galaxies move as if there is more gravity present than visible stars, dust, and gas can explain.

Gravitational lensing maps hidden structure

Mass bends the path of light. Measuring distorted background galaxies reveals where unseen matter is concentrated.

It helps shape the cosmic web

Large-scale structure appears as clusters, filaments, and voids. Dark matter helps guide that gravitational pattern.

The particle identity is still unknown

Evidence strongly points to gravity, while the underlying particle physics remains an open scientific question.

This artwork is conceptual. The filaments, nodes, pointer lens, and click pulses suggest invisible gravitational structure, not a numerical cosmology simulation.
