Does there exist a set [tex]X\subset\mathbb{R}[/tex] that has a property
[tex]
m^*(X\cap [0,x]) = \frac{x}{2},\quad\quad\forall x>0,
[/tex]
where [tex]m^*[/tex] is the Lebesgue outer measure?
My own guess is that this kind of X does not exist, but I don't know why. Anybody knowing proof for the impossibility of this X?
