Disjoint disks
What if we have a disk centered at $(0,0)$ of radius $r$, and another one centered at $(\epsilon,2r+\epsilon)$ for sufficiently small $\epsilon$, and so on? Then we can have a disk with centre at every possible real distance along the $x$ axis. This is what I meant previously.

sufficiently small মানে বুঝলাম না। যাই হোক, যদি মনে হয় আসলেই real axis এ সবগুলারে বসানো যাবে, বসানো হোক, who cares ...
