I have some dumb questions:
If they didn’t find a moon around Eros how does that establish the exploded planet hypothesis?
How exactly does a planet explode?
TVF said the opposite — that asteroidal moons are predicted by the EPH, and not by any other model. My feeling is, and has been, that asteroidal moons are a pretty trivial thing, and have nothing much to say about the likelihood of the EPH, but it made a nice sidebar. :’)
And regarding how does a planet explode, TVF offered one scenario (overspin) which would/might only apply to recently formed bodies (or bodies which recently got added to in some significant fashion), yet he posited an EP sometime in the last 10 million years, another one sometime shortly before the K-T extinction, etc.
