Interesting topics and guest suggestion

Hi Greg,
I've been really enjoying your shows for a while now. Thank you.
One area/topic I would like to hear more about are the various prophecies out there. I don't know of anyone who is an expert in this area but I'm sure if you could find one, it'd be a very interesting show.
Have you heard of Drunvalo Melchizedek? I stumbled onto one of his youtube Q&A videos. He was talking about some pretty out-there discoveries (from Russia) like Mars and the moon relatively rapidly growing an atmosphere in recent decades... other things too, which I will look into further some time but thought I'd throw his name into the ring.
Take care.
Justin.
