When its initial distribution is seeded by the cosmic microwave background, it gives an explanation for large-scale structure formation, and gravitational lensing of the Bullet cluster provides evidence for it.

The current (*) cosmological standard model favors a "cold" variety of it, and it's first proposed by Fritz Zwicky based on his study of rotational velocities of galaxies.
