The thing is perspective. In our 3D world we can only sense one dimension below to move forward, backward, up or down. It appears flat until we are in space(the 4th dimension) looking down at the third dimension. There is no forward/backward/up/down as a frame of reference in space or all other higher dimensions, only symmetries and hyperspace geometries. In effect the Earth and all planets have different geometries ranging from the 2nd dimension to the 11th dimension simultaneously as parallel realities in a parallel multiverse of different, varying symmetries and geometries(shapes and forms). There is at least one Earth with planets shaped like a dick and balls on that infinite scale.
