Having had a day to think about it I had some further thoughts about higher dimensions.

If our eyes can be considered our primary sensory organs for sensing the normal three dimensions, than our memories can be considered the primary mechanism for sensing the fourth dimension, but they are rearward facing.

Imagine for a moment if the eyes were mounted on the back of the head instead of the front. As you ran you could only see where you’ve been, not where you are going. That is the nature of our 4th dimensional sense. Always looking back…

The 5th dimension, or perhaps more accurately the dimensions in the 5+ range, are potentiality. Every possible decision has been made. Every choice chosen. Our 5th dimensional sense is extremely poor. We can only sense possibilities very close to our own 4th dimension. Probabilities and liklihoods that seems plausible from where we sit, universes very like our own.

The 4th dimension constitutes the configurations of universe that we will live through. The 5th dimension is superset of those configurations representing both the configurations that we live through and the configurations that we don’t. These other configurations would be part of the 4th dimension if we (or others) had made different choices. They possibilities that the we at this moment did not experience.

I’m not sure that there can be said to be an us when discussing the future (or the past).. There are the myriad of potential us. Some lie on the path that got us to this point and some do not. For the future, there are a million potential us. Each will look back at a different 4th dimensional path, Each will consider themselves the real one, the one that really happened. All will be wrong. They all happened, they are all out there.
