Middle Earth as a Parallel Universe

[Amarie of the Vanyar]

Lush:

So the Undying Lands do not fit into the four-dimensional universe we are used to perceiving, but they are, at the same time, inside the eleven-dimensional universe? I don't know if that makes sense to me, because wouldn't that mean that they are, in fact, situated in the other seven dimensions that we cannot notice? See what I mean?

Yes, that is what I suggested. But Aman can also be a four-dimensional 'universe' (it doesn't need to be converted into a seven-dimensional universe).
Let's consider that our universe is in the 0 coordinates for all the seven dimensions that we cannot notice. Then Aman can be in a coordinate different to 0 in any of this seven dimensions. In this case, it would be unreachable for men, but could be reached by somebody that can move along this dimension (the Straight Road).

Also, going with the thought in the previous paragraph: what would the whole dimension-thing make of Tuor?

I am sorry, but I don't understand this question. [img]smilies/frown.gif[/img]
