I have indeed. I had an interesting chat with them. I posted it because it sounded interesting especially the crystals been found near the earth's core part of it. (I love crystals as I think they're very beautiful so it caught my eye but I found it fascinating when I got a chance to read it properly.) I didn't have a chance to read it properly when I 1st posted it as I'd just got back from pottery class.You've got interesting customers. Now I understand why you've posted some intriguing geophysical news and questions on science thread. I hope those experts won't deny/contradict pieces of information that I posted on said thread,
