Nearly a century of observations, from galaxy clusters to the cosmic microwave background, have built a compelling case for dark matter's existence, but in recent years, the leading candidates for this mysterious matter have been coming up short.. Enter black holes. Tiny ones. David explains how so-called primordial black holes that formed in the first moments after the Big Bang could possibly be all our dark matter… if they exist at all. Fortunately, this is a testable theory, and David explains the exciting new experiments that could potentially lay this cosmic mystery to rest.
