TITLE: Uncountable collection
QUESTION [5 upvotes]: Is there an uncountable collection of compact disjoint subsets of the real line such that each element of the collection is uncountable?
Thanks.

REPLY [5 votes]: There exists a continuous surjection from $[0,1]$ onto $[0,1]\times[0,1]$. For example, the Peano curve. Pick such function and denote it by $f$.
For every $r\in[0,1]$ consider $A_r=f^{-1}(\{r\}\times[0,1])$. This is the preimage of a closed set under a continuous function, therefore $A_r$ is closed, and it is a subset of $[0,1]$ so it is bounded. Therefore it compact.
Finally, $[0,1]$ is the union of all $A_r$'s and there are $2^{\aleph_0}$ of them, each can be mapped onto a set of size continuum, and therefore is uncountable.
So $\{A_r\mid r\in[0,1]\}$ is an uncountable collection of pairwise disjoint, uncountable compact sets.

REPLY [3 votes]: Yes. For $t=(t_1,t_2,\dots)\in\{1,2\}^\mathbb N$, let $A_t$ be the set of all real numbers whose continued fraction is $$ \frac1{a_1+\frac1{t_1+\frac1{a_2+\frac1{t_2+\frac1{\dots}}}}} $$ where each $a_i$ is $3$ or $4$. This is a Cantor set, and the $A_t$ are pairwise disjoint.
Of course, that I used only the numbers $1$-$4$ in the continued fractions is irrelevant. To illustrate the flexibility of the method, see here for a related result.
