Enjoyed your record analogy and concur. Philosophically I'm of a different overall view, that space is not 3D at all, the three dimensions are imposed by our consciousness in its assessment of objective reality. The three dimensions are proprioceptive, subjective, that is where the concept arises. Rudolf Steiner indicated it was a grave error of materialistic consciousness in the development of Western scientific thought to externalize them as a metric of space. Space functions on projective geometry, with a spatial-counterspatial polarity. Space is space, there is no fundamental direction. Can't explain this all in a soundbite, just throwing in some perspective into the discussion. Will have to do a writeup on it.
Thanks for your post :)
