For those who are curious, a Cantor set is (without getting too precise
and mathy) a set that is closed but disconnected. The cannonical example
is the Cantor Middle-Thirds set, which is constructed by removing the
middle third from a set, removing the middle third from the remaining
sets, etc. This results in "a lot" of intervals :)
