I'm trying to build a universe with interactions between beings from different dimensions. Only dimensions 3 and up would be capable of spawning any sort of life. The most interaction would take place in the third dimension. So what would a being from another dimension look like if it came to our lowly third dimension and what would it be capable of doing?
I understand that this question tests the limit of human understanding, but please make the most educated guess you can based on current theories and such.
0: A single point in time and space
1: An infinite line (x-axis)
2: An infinite plane (x and y-axis)
3: An infinite cube (our universe, x,y,z axes)
4: Fourth dimension is time, which governs the properties of all known matter at any given point.
5: A world slightly different from our own that would give us a means of measuring the similarity and differences between our world and other possible ones.
6: A plane of possible worlds, where we could compare and position all the possible universes that start with the same initial conditions as this one (i.e. the Big Bang). In theory, if you could master the fifth and sixth dimension, you could travel back in time or go to different futures.
7: We have access to the possible worlds that start with different initial conditions. Whereas in the fifth and sixth, the initial conditions were the same and subsequent actions were different, here, everything is different from the very beginning of time.
8: A plane of such possible universe histories, each of which begins with different initial conditions and branches out infinitely (hence why they are called infinities).
9: We can compare all the possible universe histories, starting with all the different possible laws of physics and initial conditions.
10: We arrive at the point in which everything possible and imaginable is covered. Beyond this, nothing can be imagined by us lowly mortals, which makes it the natural limitation of what we can conceive in terms of dimensions.
