We know that given our standard theory of gravity, there must be more mass out there holding things like our Milky Way Galaxy together than we can see--a lot more mass. Our suspicion is that this missing mass is composed of a new kind of "dark matter". In this video KIPAC's Andrea Albert interviews Southern Methodist's Jodi Cooley-Sekula and Stanford's Alex Drlica-Wagner and asks them to explain both what we currently know about dark matter and what we hope to find out in the coming years.
