Continuum hypothesis was proven, with an proving method called "forcing", to be undecidable under commonly accepted axioms of the set theory. This means that neither continuum hypothesis nor it's negation follows from this axioms just like one axiom (or it's negation) in some consistent axiomatic system does not follow from other axioms. Therefore, continuum hypothesis or it's negation could be added as an additional axiom to existing commonly accepted axioms of the set theory.

An aleph-one is the second of the transfinite cardinal numbers, which, according to the continuum hypothesis, corresponds to the number of real numbers.

The Continuum happened in 2008.

a close continuum is a continuum extending from which describes the extent to which environmental conditions affect performance.

The Gernsback Continuum was created in 1981.
