| Description | Assures him that Professor Gold does not believe that large rocks can be moved by electrostatic forces. Large rocks ejected form craters can be still found on the moon in the position where they landed. Also, rays light in colour and starting at large craters are indeed observed by telescope from the earth. In many instances, however, these rays are covered up by darker dust, probably by means of the transport phenomenon described by Dr Gold and thus they are not visible from the earth. |
