(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.
The Big Bang singularity is the most serious problem of general relativity because the laws of physics appear to break down there, Ahmed Farag Ali at Benha University and the Zewail City of Science and Technology, both in Egypt, told Phys.org.
