Things may be stored differently from the way I experience them

For some

'Information' isn't stored. Information is accessed from parallel realities which we automatically choose (unconsciously) as it is needed and relevant.

You did a good job on the 4D analysis btw maybe this will help.

Think of space-time as a 100% thing. The more space you have, the less time is involved. Versa-visa.

Why do two 2-dimensional sheets give you 4 dimensions?

~~ Paul

I'm assuming you mean at 2)? ...I've simply added the minimum number of coordinates needed to define a location on these unconnected 2-D sheets (spaces) together, as a way of trying to explain an idea.

To specify a location among two 2-dimensional surfaces, we need {0,1}, x, y. That doesn't get us the third and fourth continuum dimensions. Yet you said it equals 4D. That's what has me confused.

~~ Paul

I don't understand the maths you've written, so can't really help.

To specify any point on two 2-dimensional surfaces, we must specify which surface (0 or 1), then the x, y position on that surface. What we don't have is a complete 4-dimensional continuum, where we would specify x, y, z, w. Two 2-dimensional surfaces are not equivalent to one 4-dimensional hyperspace.

~~ Paul

If it's analogous to 3D space + 1D time = 4D, then it's not a question of specifying one or the other, and then a location in the one you've specified. Each point will have a location in both of the 2D spaces - that is, 4 coordinates, which does amount to a 4D space.

I'm not saying I really understand it, mind you.

It's two points, one in each of the 2D spaces, because you can't allow:

point A at 1, 2 and 3, 4
point B at 5, 6 and 3, 4

If you do, then two points are sharing the same position on the second surface.
