Of course, most people can learn this. It just takes a decade of continuous study. This is the crux of Flying Lemon's argument: credentials and titles don't mean shit, per se. But they show you have been subjected to a harrowing experience of learning and understanding, and so you have a firm grasp of the topic. If are going to study something deep enough to know it as well as a PhD, then you might as well get one. Well, if it helps (probably it doesn't), I don't think anything bad about your post. It's just a harmless, weird idea that popped into someone's mid. Also, it has some similarity with brane cosmology, so it's not completely out of the blue. What I'm arguing against is the position of "it doesn't make sense to me (i.e. I don't understand it), so it must be wrong". Maths is as "true" as you can get. Literally, you can't make it "truer" than that. But even ignoring that, if you don't speak the language, that would make your opinion about its literature somewhat... limited, don't you think? On the other hand, why should the stuff in the universe be intuitive, easy to observe and understand for us? That's just anthropocentrism speaking. Quantum mechanics is definitely counter-intuitive and weird, and yet it's both formally correct and highly predictive. The universe isn't limited by the perspectives of puny brains. Ah, "teach the controversy". I see. If that counterargument was conjured by "someone smarter than yourself", then I weep for thee. Well, given the popularity of homeopathy and other similar "alternative theories" , I guess they kind of do. Which is kind of how science works. I'd love to see the "data" in theology. Also, given how many confirmed predictions have been carried out based on "dark cosmology", you are talking out of your arse here.
