Timeline for If $M$ is a manifold, $x∈M$ and $d(x,ω)=\inf\{t>0:x+tω∈M\}$, does the pushforward of the solid angle measure under $S^2∋ω↦x+d(x,ω)ω$ admit a density?

Jan 17, 2020 at 20:54	comment	added	Ben McKay		What is $\mathcal B(M)$? Is $M$ a surface, i.e. a 2-dimensional manifold, or can $M$ be 1-dimensional or 0-dimensional, or 3-dimensional?
