For anyone who doesn’t know what’s happening: shadows blur when farther away from what’s casting them because light sources typically emit light over some area rather than a single point. At the edges of the shadow, the light source is only partially obscured; this is continuous which leads to the blurring effect.
It happens no matter how far away the object casting the shadow is, but it’s blurred more the further the object is because it gets smaller relative to the light source as viewed from where the shadow is.
