>>14102214when i saw Carl Sagan's really old demonstration about the fundamental differences between 2d and 3d space, where he used imaginary "2d flatlanders" as an example, whereby a 2d flatlander had no concept or perception of anything beyond a pure 2d world,
it really struck me that perhaps, we living in our 3d space world, my be like the 2d flatlander with our own relative limitations of perceptions.
and there could be other dimensions of space beyond 3d that we as "3d worlders" cant perceive or detect.
its practically mind boggling to think about. could we start with a presumption that if we follow the construct of our 3d cartesian framework where x is perpendicular or at 90 deg from y, and z is perpendicular or at 90 deg from plane described by x & y, then might a 4th dimension of space exit which is somehow perpendicular and at 90 deg from our x,y,z 3d space?
is this the imaginary tesseract?
is a tesseract actually a reasonable and practicable theory?
