Single Idea 9555
[filed under theme 6. Mathematics / A. Nature of Mathematics / 5. The Infinite / g. Continuum Hypothesis

Full Idea
Cantor's Continuum Hypothesis was that there is no cardinal number greater than aleph-null but less than the cardinality of the continuum.

A Reaction
I have no view on this (have you?), but the proposal that there are gaps in the number sequences has to excite all philosophers.
