I've had this crazy thought for awhile that the physical dimensions we see are the three dimensions of gravity, and that there are a similar number of dimensions for time.
I have an "everything moves at c" hypothesis, wherein everything has an inertia/velocity vector with 3 spatial (squares to 1) components and 3 temporal (squares to -1) components. The magnitude of every vector is c.
We see three spatial dimensions, because the portion of our vector from the temporal components is almost c. Our inertia makes it very difficult to change our directional vector through the temporal dimensions, because we are almost at rest in the spatial dimensions. So we see time as a single dimension, because it is practically impossible for us to change the temporal-only components of our vector. Similarly, for an electron, when the spatial component of the vector is nearly c, it would perceive space as one dimensional, and would require less energy to change direction in the temporal dimensions. This results in spatial behavior that requires the use of probabilities.
We perceive up-down, left-right, front-back, and before-after. Someone moving at near-c through space might perceive to-fro, entropy-order, likely-unlikely, because-causes, or similarly incomprehensible-to-us dimensions.
This hypothesis is all thanks to the Back to the Future movies. Why does the DeLorean have to go 88 mph? Because the Doc could only generate 1.21 GW, and in order for that much energy to change your direction through time, you have to be moving at 88 mph. If you were going 120 mph, you would need less energy, but in 1985, 88 was about as much as you can expect from a commodity automobile. It also received significant contribution from quaternion-based mathematics, which is completely symmetric with respect to dimensional signatures of (3,1) and (1,3).
you probably missed all the history and context of DeLorean :) (In all other respects, your comment sounds interesting).
