If I understand that you want to know when a ray of a certain distance does NOT collide with something? Then it just doesn't.

   var hit : RaycastHit;
     if (Physics.Raycast (transform.position, -Vector3.up, hit)) {
         var distanceToGround = hit.distance;
     }
     else
       print ("it did not hit anything");
