Infinite set that is not countable / From Wikipedia, the free encyclopedia
"Uncountable" redirects here. For the linguistic concept, see Uncountable noun.
In mathematics, an uncountable set, informally, is an infinite set that contains too many elements to be countable. The uncountability of a set is closely related to its cardinal number: a set is uncountable if its cardinal number is larger than aleph-null, the cardinality of the natural numbers.
