Subject	has definition	is a kind of
singularity	If the standard big bang theory is extrapolated all the way back to time zero, one reaches an instant of infinite density, infinite pressure, and infinite temperature - an instant that is frequently called the initial singularity. This singularity is sometimes said to mark the beginning of time, but it is more realistic to recognize that an extrapolation to infinite density cannot be trusted.	theoretical celestial body
naked singularity	A singularity that will be visible and communicable to the outside world.	singularity
