General topology | Properties of topological spaces
In topology and related branches of mathematics, a totally disconnected space is a topological space that is maximally disconnected, in the sense that it has no non-trivial connected subsets. In every topological space, the singletons (and, when it is considered connected, the empty set) are connected; in a totally disconnected space, these are the only connected proper subsets. An important example of a totally disconnected space is the Cantor set, which is homeomorphic to the set of p-adic integers. Another example, playing a key role in algebraic number theory, is the field Qp of p-adic numbers. (Wikipedia).

What Are Cosmic Voids? The Biggest Nothings in the Universe
We talked about the biggest structures in the Universe, but what about the opposite? The biggest empty spaces in the Universe, the cosmic voids that separate the clusters of galaxies. Check out our interview with Paul M. Sutter, a specialist on cosmic voids: http://www.astronomycast.com/2
