Gravitational theory alternative theories

As already mentioned, an alternative theory postulates a gravitational collapse of accretion disk material without first forming planetary cores (Cameron, 1978). In this case one would expect all of the outer planets to contain elements in nearly the same proportions, very similar to that of the Sun. Small increases of heavy elements over solar abundance ratios are possible from a post-accumulation infall of planetesimals, but the large enrichment of some of the heavy elements, as indicated in Table 9.3.1, caimot be explained. In contrast, the theory suggesting core formation to have occurred before the bulk of the low-Z gases arrived readily explains such an enrichment. 

It only remains to add that Einstein would probably reject the theory of multiple space-time systems which I have been expounding to you. He would interpret his formula in terms of contortions in space-time which alter the invariance theory for measure properties, and of the proper times of each historical route. His mode of statement has the greater mathematical simplicity, and only allows of one law of gravitation, excluding the alternative. But, for myself, I cannot reconcile it with the given facts of our experience as to simultaneity, and spatial arrangement.
