[quote=@Disdain] Help with...? You're not giving me any specifics here. And you can't expect me to do a bunch of calculations and inexplicably come up with what sort of a thing that object is. That's not how it works. Also, I don't see how you can deduce by the patterns of a wear that the rock is unnatural. They could just indicate extremely unusual wind patterns. In fact, right now I'm simulating exactly how that would play out over a number of years. [/quote] .... *walks over to the rock, and knocks on it, proving that the inside is hollow* It's unnatural because it isnt really a rock at all. It's made out of metal. I was asking you to make an opening without being destructive. So, what about my deducing?
