The deteriorating factor...dugdeep said:Not to hijack this thread away from Jim Humble and MMS, but I definitely think Sircus is losing credibility. He seems OK when he's on topics he knows, like medicine, but when he starts talking about comets etc. he's really out of his element and it shows. It seems like he's just picking up hearsay, using homemade youtube videos as evidence. "The source, NASA, is impeccable"?!?! Gimme a break He should know better.
