You know, there are a great many threads on this forum regarding the multiverse and the possibility that Equestria is real and "out there" somewhere. The argument is pretty much the "infinite number of monkeys" argument. Given an infinite number of monkeys sitting at an infinite number of computer keyboards, eventually one of them has to accidentally type out, by virtue of hitting keys at random, the complete works of William Shakespeare.
To extend the thought experiment, any possible combination of words (i.e. every story ever told) would have to be produced. Good luck finding it among all those simians, though.
That's fine as far as it goes. But I would give you another image. Sitting at a table and having an infinite amount of time to roll a 6-sided die (die is singular, dice is plural), no matter how long you sit and roll that cuboid sucker, you ain't ever gonna get seven. I doubt any region of the multiverse is conducive to Flash-animated sentient horses.
So, is our universe an infinite number of monkeys on keyboards, or it is a roll of the die? I don't know, and I don't really need to know in order to decide. Because essentially, even if theoretically sound, the Equestria so postulated could not be reached by any foreseeable means. Which means it might as well NOT exist in the practical sense.
So, I guess my point is that we can't yearn after a vision of Equestria. We have to live here in the real world. It's got plenty of wonder and the magic of friendship to spare. Go get it.
