text: Its existence is inferred because the galaxies and galaxy clusters should swirl apart in a few million years, unless there's something odd with gravitation, or there's a mass that we can't see (the latter being dark matter).
text: Its existence is inferred from gravitational effects, and it is predicted to account for approximately 22% of the total mass/energy content in the universe (normal matter accounts for only 4%).
text: Instead, the existence and properties of dark matter are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe.
text: Although dark matter has not been directly observed, its existence and properties are inferred from its gravitational effects, and it is estimated to make up 84% of the universe's mass and 23% of its mass-energy.
