 We've got amnesia for it. If I agree to it, I think it was Graham Hancock that said we've got historical amnesia about our past. In the past, it was used to move large stones and other things to create structures and so on. And if you get a chance to look that up, again, it's the Calusa-Klein gravitons. And type in Mark D'Anatonio. And that's his theory on how these UOPs move.
