The former yielded the unexpected evidence that an ancient lunar em field involved in the formation of 3.9 billion year old rocks, had the potential of 1 gauss (i.e. virtually twice the present polar field of the Earth); the latter implied the existence of magnetic—field regions above the lunar surface indicative of the presence of highly magnetized, crustal rock. Piecing together his evidences, and employing the full armamentarium of allowable scientific analysis against a "sitting—duck" case that conveniently buries any of those (duly reported) facts which just aren't promisingly proportional to Procrustes' measurements, the Professor comes up with his Reasonable Hypothesis. In the ancient past the Moon must have had a molten iron core; by the process of "two-cell" convection, heated materials would circulate in double columns toward the surface, cool and drop. This pattern would not only generate the necessary magnetic field, but it would account for the evidential lack of an overall, dipole field of the lunar crust such as one finds on Earth. Simple dipoles generated by the mechanism of this internal dynamo, couldn't account for the topographical contours in the map of magnetic anomalies (the depth of a given dipole corresponding to each measured point would have to surpass the limit where ambient underground temperatures exceeded the Curie temperature for materials and so lost their magnetism, thus being unable to participate in the mechanism of solid-state convection powering the fields and accounting for long-term maintenance of the equatorial "bulge"). On the other hand, making computer—modeled adjust— ments of the various field strengths and directions for the anomalies, the Professor and colleagues succeeded in simulating uniformly— magnetized discs of material on or near the surface. Significantly, these traced discs showed superposed rotational patterns, each disc spanning great distances of uniform magnetic direction in order to account for the heights of the strong fields above the surface while demonstrating distinct sets of magnetic poles; this suggested a longterm process of polar wandering, in which the Professor hypothesized that successive satellites of lunar—circling orbits must have been pulled in by tidal forces and impacted equatorially to shift the balance of the "bulge" about the precessing axis. Thus the lunar mass itself would have reoriented periodically about its own axis, even reversing the evidential poles, thus maintaining the necessary alignment between spin and magnetic axes suitable to the Coriolis force. Okay, Professor: this is fine, except for two minor things (in the spirit of spaceage generosity, we're keeping it to two, since we've agreed to accept the professionals on their own terms; it wouldn't be de rigueur to expect the scientific community to account for the evidences which it, itself, duly catalogues and then ignores). First, two—cell convection of the type Professor Runcorne describes can't occur within any body which doesn't have a dense core; such a core is the source of the intense heat that drives the "solid-state creep" of the mantle, between the rigid lithosphere and the molten interior; but by just that token it can't participate in the actual convection. Thus the Professor calculated that the Moon must have an iron core between approximately 300-500 kilometers radius. This implies of course that the highly intense magnetic field of 1 gauss which deposited the fossil evidence of 3.9 billion year old moonrocks, was generated by a core many times smaller than the Earth—which has no such comparable samples. Even the scientific community seems to have greeted woud ao a tata And secondly, the actual mean lunar density doesn't approach what would be required for such an iron core (which is why such a core was never considered a recommendable hypothesis before the mysteries of the returned lunar rock—samples); it is in fact much nearer the density of the ferromagnesium silicates comprising Earth's upper mantle. Taking much the same "surface" evidences into account, now, initiated understanding may be able to tell us what picture is formed by the traces, and at the same time may be able to use that picture to account for those elements of the 3rd—stage scientific worldvicw which are discarded so as to preserve the _ ate (Oat a 158 T-Bird_Vs_The_Flying_saucers.htm that hypothesis with some dubiety. presentation of flatland non—ambiguity.
