What Is Dark Matter | Modified Curriculum

Dark matter is a hypothetical and invisible form of matter that does not interact with light or other electromagnetic radiation. The existence of dark matter is supported by observations of [[galaxy-rotation-curves|galaxy rotation curves]], [[gravitational-lensing|gravitational lensing]], and the large-scale structure of the universe, as described in the standard [[lambda-cdm-model|Lambda-CDM model]] of cosmology. Dark matter is thought to serve as gravitational scaffolding for cosmic structures.
