For every $n \ge 2 $ , does there exist an uncountable family $\{D_\lambda: \lambda \in \Gamma\}$ of mutually disjoint closed
balls in $\mathbb R^n$ , such that $\mathbb R^n \setminus \cup_{\lambda \in \Gamma} D_{\lambda}$ is path connected ? ( I am also allowing points to be closed balls , of radius $0$ )
Just take $(x,0,0,\ldots,0)$ where $x\in\Bbb R\setminus\Bbb Q$. Each point is a ball of radius $0$, clearly disjoint from every other ball, and the complement is certainly path connected.
