Abstract
In the view-obstruction problem, congruent, closed convex bodies centred at the points ½ , …,½+Zn in Rn are expanded uniformly until they block all rays from the origin into the open positive cone. The central problem is to determine the minimal blocking size. In the case of spheres of diameter 1 and cubes of side 1 these values are known for n=2, 3 and 4. Here we show that in R5, this value for the sphere of diameter 1 is √41/42.
