"Ordinary” matter that we encounter in our daily lives only accounts for a small amount of all the stuff out there in the cosmos. Significantly more of that stuff is dark and mysterious, something scientists refer to as dark matter. This short video introduces the theory of dark matter and some of the ways that scientists are trying to detect dark-matter particles using direct and indirect methods.
