Aleph-1
The Set Theory symbol for the smallest Infinite Set larger than Aleph-0. The Continuum Hypothesis asserts that 
, where 
is the Cardinality ofthe ``large'' Infinite Set of Real Numbers (called the Continuum in SetTheory). However, the truth of the Continuum Hypothesis depends on the version of Set Theory you are usingand so is Undecidable.
Curiously enough, 
-D Space has the same number of points () as 1-D Space, or any FiniteInterval of 1-D Space (a Line Segment), as was first recognized by Georg Cantor.
