comment Show that a given set has full measure or measure 0
Okay Bungo is right. To get the desired result I want to have that $m((E+(x-y)) \cap (x-\epsilon,x+\epsilon)) = m(E \cap (x-\epsilon,x+\epsilon))$. I will think a moment about that. Does it follow from density of $\mathbb Q$ in $\mathbb R$ that $m(E \cap I) = m((E+z) \cap I)$ for every open set $I$ and real number $z$ ?

comment Locally compact Hausdorff space and indicators
Thanks, I was too heavily busy wanting to prove this with opens, which is not handy in this case.

comment Measurable subset of unit circle invariant under translation by infinitely many points.
Is it obvious that a point cannot be a density point for $E$ and $E^c$ simultaneously ?

Why do you believe your answer is false if you calculated it ?
