'''Infinity''' means unlimited, impossible to lessen.  Appreciation of infinity is remarkably useful intellectually and even on a personal level.  Some infinities are larger than others, as shown by the mathematician [[Georg Cantor]].

Understanding infinity has advanced many fields, such as [[mathematics]] through [[calculus]], [[set theory]] and [[singularity|singularities]], [[quantum mechanics]] through infinite [[uncertainty]], and [[physics]] through the [[Big Bang]] (infinite [[energy]] density) and the speculative [[black holes]] (infinite mass density).
