No. 118: Jul-Aug 1998
In a late-1997 issue, Geophysical Research Letters published a group of five papers that detailed five different lines of evidence that are inconsistent with the claim by L.A. Frank and J.B. Sigwarth that the earth is bombarded daily by 30,000 house-size icy comets. If such bombardment has really been occurring, scientists would have to rethink the origins of the earth's oceans, terrestrial life, and the formation of the solar system. No wonder the icy-comet hypothesis is strongly challenged!
Three of the more interesting points made by this group of papers are as follows:
Preceding this series of five papers is one by Frank and Sigwarth in which they describe their detection of atomic oxygen trails near earth. These they attribute to small icy comets.
