To black cube in multi D you need to define the muli-dimensional tensors and manipulate them thus manipulating the encompassed dimensions.
The Black and Yellow shaded areas are inter-dimensional tensors - like Einstien Tensors. The center box is the bubble of 4D reality by manipulating the angle of the energy and vibration you change the 4D (space-time). Internally this can change your world by opening doors. Mechanically it can be used to change space or time.
