Recent observational evidence from astrophysics suggests that 80% of the matter in the Universe is some new type of matter not present on Earth or identified in laboratory experiments, the laws of gravity must be modified on very large distance scales, or a combination of both. However, laboratory efforts to produce or detect the dark matter particle have ruled out most candidates. After explaining state of the art constraints from astrophysical observations and laboratory experiments, this talk discusses what options are left and possibilities for studying dark matter.
This lecture builds on our Fall program "Dark Matter: Evidence, Experiments, and Properties" available here.
