(Beginner) Reading astronomy books, I've come up with the word singularity a lot, but I can't figure out what it exactly means. A singularity means a point where some property is infinite. For example, at the center of a black hole, according to classical theory, the density is infinite (because a finite mass is compressed to a zero volume). Hence it is a singularity.
