He did nothing of the kind. Read the article again.
He took a Science article written in 1963 and pulled a factoid out of it.
Ok, fine, it's not the author of the article who tested the rock, it's the scientist he was referring to. But I keep telling you that multiple lava flows have been tested by multiple scientists with similar results. You said he posted false information. So what was false?
Except the factoid was not in the article in which he claimed it was. That means he must have pulled the factoid out of somewhere else.
