we live in a 3d world. up/down, left/right, back/forward. all of this moves forward in time, the way our consciousness percieves things.
imagine how a 2d cosciousness would percieve things.
back/forward, left/right.......no up or down.
the entire up/down modality of our existance would be invisible to a 2d consciousness. if anyone in a 2d world found a way to move up or down, they would only flick into view as thier movement crossed the 2d plane. depending how fast a person was moving relative to the 2d space they would only be seen as a flash or blip.
just as a consciousness that can move back and forth in time will only be seen by 3d entities at the point where they intersect the 3d cube.
time exists at right angles to all points in the 3d cube. that`s why we can`t actually see time travelling consciousness in 3d space.
it`s the same reason that consciousness in the 2d plane has no access to 3d movement or consciousness.
at this point (cube, in 3d.....) i will stop so that the concept can sink in.
if it does actually sink in, let me know. i`m still working on it.
