Cosmologists at Perimeter Institute seek to help pin down the constituents and history of our universe, and the rules governing its origin and evolution. Many of the most interesting clues about physics beyond the standard model (e.g., dark matter, dark energy, the matter/anti-matter asymmetry, and the spectrum of primordial density perturbations) come from cosmological observations, and cosmological observations are often the best way to test or constrain a proposed modification of the laws of nature, since such observations can probe length scales, time scales, and energy scales that are beyond the reach of terrestrial laboratories. | more on cosmology |

Cosmology is particularly exciting since, in the coming years, it is likely to receive qualitatively new observational input (e.g., from the Large Hadron Collider, direct dark matter searches, indirect astrophysical dark matter searches, cosmic microwave background polarization experiments looking for the signature of primordial gravitational waves, or large scale structure observations searching for the imprint of primordial non-gaussianity). Cosmology connects strongly to other research at Perimeter Institute being done in the areas of particle physics, quantum gravity, string theory, and strong gravity.
