Could scientists be wrong about dimensions---could distance, time and energy just be a step forward or back in xyz directions at a basic level? A time-line is linear and to change the time line into 3-D make group identities from a line xyzxyzxyzxyz----and so on. Then choose one from each xyz group.......................................y.x... ...z..-y--and so on to make a 3-D path identity. notice the -y in the 3-D path this means moving back in time. The last point on the path if set one unit from the start will alter all steps there after by one point chronologically. Why wouldn't nature do this? A step would be a perfect measure for distance, time and energy all in one and the fastest thing in the universe---zillions of times faster than the speed of light.
