Are you calling Mr. Voorsanger a liar?
No, he is mistaken. Just the same way that someone says, "boy that was a hell of a bang, what an explosion!", only to be told that what he heard was a large balloon going pop.
He says molten x,y,z, but he doesn't clarify this. Infact he is as much use as my friends 3 year old, because he simply asserts it. If he said, "hay yeah! I saw red pixies dancing in my garden at 3am!", would you believe him? If not why not? Tell us how that is any different to him standing next to the "meteorite" claiming "molten metal" as it is to him standing in his garden claiming the existence of red pixies.
There IS zero difference.
He does not point to specific areas of the lump and say, "look, look at this bit, this bit here, it has these characteristics that indicate this and this, and because of this you can claim liquid metal". He does nothing of the sort, he just says it without any justification. If I were an amateur in court and this guy was claiming molten metal and I was opposing his side, I'd be able to show very quickly that he's not able to do so and therefore it would be shown that he has no justification for his claims.
As a metallurgist who has carried out investigations, one of which, ultimately lead me to being in court and therefore questioned on technical matters*, I can safely conclude that Voorsanger's narrative would be ripped apart. He makes a statement and that's it, he does not back it up - If someone wanted me attend court and show why his was wrong it would be a pleasure.
*Christ that was bad, but not as bad as an audit I once had concerning material and statistical standards whereby the bloke who was doing the audit had written two of the bloody standards and was an "amateur" buff on the others! We didn't realise he was and he screwed us down tighter than a medieval king's daughter's chastity belt! We passed, but it was hell.
