I'm going to have to chew on this one for a while; I couldn't help myself--I watched the one on the 11th dimension as well, where he clarifies that the 4th dimension is not really time but duration, since time is merely one of the directions of that dimension. This is fascinating stuff, and if you like it, you'll enjoy reading William Sleator's The Boy who Reversed Himself, a juvenile fiction book.
My first impressions are that, as I said before, having many dimensions explains how God can know the future, because to him, it's just a point on a line that he can look in on and observe and try to explain to us in terms we can understand. It also explains how Philip could have traveled "in the Spirit" to come across the Ethiopian who needed to hear the Gospel.
I agree with you that these theories explain how God could know all possible time lines in all possible beginnings as I am a believer in causal determinism, but given this point -- you also have to understand that free will is an illusion, which would make a series of gods into liars (including the holy Christian trinity). And this is so for a number of reasons, one being that the expressed purpose for life on earth (according to the Christian Bible) is to live in the world of sin and still choose God. But if your choice has already been decided, what sense does that make?
If you take it one step further -- if every choice you could ever make exists in the series of time lines where "you" exist, which would determine whether you get into heaven?
Whew, my brain is pooped from all this theoretical thinking!
The problem I see with this is that, if there are really 10 dimensions as he described, there are alternate universes where things didn't go as God planned, i.e. Christ didn't die for our sins and doesn't ultimately win the battle against Satan. And if that is so, then God is only all-powerful in regards to this one universe that we're part of. Yet God claims to be the God of gods, the King of kings, the Lord of lords--you get the picture. So either he is a liar (in regards to not reporting the full truth) or there aren't multiple universes, or I'm missing something. And I have questions--maybe dumb ones, but I'll post them anyway. If there are multiple universes, why do we all exist in the universe that has this religify.com website in it, or even us in it, for that matter? Why can't we access the other universes?
Well, if there are multiple time lines containing even the most slightly shifted atom as the difference between one and the next, you can bet that "you" exist in a limited set of them and the same goes for everyone else. Essentially, they're saying that multiple dimensions allow for all possible variations on everything (limited by the initial ingredients of the big bang, of course). That would mean this website would exist in a set of them along with you. Why we exist with it, I do not know. I think human access to other dimensions, given enough time, is possible.
The other thing I'd like to touch on (that we should put up a different thread for entirely) is any 'battle' between good and evil -- in this case God and the devil.
If God is all-powerful, all-knowing, ever-present, etc., then how in the world would a fallen Angel (God's creation) have any effect on him what-so-ever? All-powerful means being able to create or destroy (or anything in between)
anything. But again, this is an entire debate unto itself. Just wanted to get that out there.
