At KIPAC, we aim to understand the nature of dark matter by studying its behavior in diverse cosmological settings.
- Dark Matter & Dark Energy - Science@NASAMatter is defined as any substance that has mass and occupies space. But there’s more to the universe than the matter we can see. Dark matter and dark energy are mysterious substances that affect and shape the cosmos, and scientists are still trying to figure them out.

- Dark Energy and Dark Matter | Center for Astrophysics | Harvard ...Dark matter makes up most of the mass of galaxies and galaxy clusters, and is responsible for the way galaxies are organized on grand scales. Dark energy, meanwhile, is the name we give the mysterious influence driving the accelerated expansion of the universe.
- Dark matter | Definition, Discovery, Distribution, & Facts - Britannicadark matter, a component of the universe whose presence is discerned from its gravitational attraction rather than its luminosity. Dark matter makes up 30.1 percent of the matter-energy composition of the universe; the rest is dark energy (69.4 percent) and “ordinary” visible matter (0.5 percent).
