It has been suggested over in the topic Can science say anything about a Creator God? that anything which exists outside the physical laws of our universe is supernatural.
This is a terrible argument. Our universe is a representative of the physical laws NOT the actual physical laws. The laws of physics aren't limited to what is found in this universe. As is always said, a tweek here or there and the universe would be different, and a multi-verse system would be how the many variations are represented.
I don't think it makes sense to say that something can "exist" outside of any physical laws, be it the ones our universe is bound by, or another variation of them. To "exist" is to be bound by some kind of physical laws.
Something that isn't bound by some kind of physical law/s simply doesn't exist. Anyone claiming they've experienced something like that is delusional.
quote:: of or relating to an order of existence beyond the visible observable universe; especially : of or relating to God or a god, demigod, spirit, or devil
This is a messy definition for two reasons.
First, beyond the obsevable universe is still more universe - it is only beyond observation from our place in the universe. As we understand the expansion of the universe, eventually everything will expand beyond an ability to observe it from Earth.
Second, none of that above information is "of or relating to God or a god, demigod, spirit, or devil" since those things are the subject of fictional books, stories and mythology.
A better definition of the supernatural would be, "something that isn't bound by any physical laws."
I would be inclined to think that what is meant by that is that those dimensions would be part of this physical universe and as a result they to would be natural.
A part of this universe and all universes that spring up in a multi-verse system. So string, or better yet, m-theory explains the multi-verse and the variations of physical laws that each individual universe can have.
I think that when we talk about other universes with a different sets of dimensions they would be called supernatural.
All the dimensions are still part of a set of physical laws. None of this is supernatural unless someone misunderstood what string/m-theory was actually saying.
Just a minor quibble:
mathematically requires additional time and space dimensions.
No additional time dimension is require. So for an 11 dimenion string theory, there's 10 space and 1 time. But cavediver has explained, and this is beyond my knowledge, that he has worked on higher dimensional string theories of upto 26 dimensions. I don't know what all that math even looks like so I could explain further.
There are so many holes in your scenario from what I see.
God is responsible for the existence of life in our universe and has a long term plan for us.
This being in a parallel universe, it is also governed by the laws of physics that establish his universe, right?
Did this being ONLY create the living things on a single planet in our universe or did the being create the entire universe (e.g. planets, galaxies, blackholes, etc.)...? In other words, did it create everything or just the living organisms on one planet?
Because these two universes are interconnected God is able to subtly speak to the hearts, minds and imaginations of humans
How? How did this being communicate all of that information about Jesus? Through some kind of magical ability to communicate or does the being have some super technology that it is able to do it with? - because if it's a technological ability and this being is also bound by a set of physcial laws, then none of this is supernatural.
However, in the middle of time He chooses one man, namely Jesus, to perfectly embody His heart for us.
We would need to know how this is done. Again, if it's just technology then it's probably super cool but not supernatural.
From God’s perspective it is all natural, and if we had perfect knowledge of God and His parallel universe it would all appear natural to us as well.
One last question. Is this being that you are calling a god, living in this other universe, is it just another evolved biological organism that has reached a level of super technology that is able to create universes and set in motion the laws of physics? Because if it is, it's super cool but not supernatural.
