(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.
1 (physics) A location where the quantities that are used to measure the gravitational field become infinite in a way that does not depend on the coordinate system. 2  spacetime singularity.  Russian: Ð³ÑÐ°Ð²Ð¸ÑÐ°ÑÐ¸Ð¾Ð½Ð½Ð°Ñ ÑÐ¸Ð½Ð³ÑÐ»ÑÌÑÐ½Ð¾ÑÑÑ f â(gravitacionnaja singuljÃ¡rnostÊ¹)
