Infinite dimensions exist. Layered in a spiral. The fifth dimension is a spiral not a "Y" It is an extension of the spiral, so that to look at it from any dimension is to see the same image, much like a fractal. Dimension have a value. Perception of these dimensions are limited by sense. (I.E. light is ours, but thermal, sound, smell, etc. exist as the PRIMARY perception in limitless combinations). While they do exist we can't "see" them due to time, size, distance and "alien sense"(ones we currently do not posses). On/off is a lie. Off is true, but on comes in infinite degrees like a dimmer switch. Like a layered circle all points break off into other realities. Information can be stored, transported, accessed and manipulated on these spirals. All is known to all of us at all times, we simply don't have the senses/awareness to "see". It is simply not what is different that we should be looking for, but what is the same in everything! The oneness that joins all is the common bond we can travel between and gives us limitless/finite (known paradox) knowledge. Travel between dimensions is impossible in contemporary means. Because we exist simultaneously in all dimensions we would have to instantly and simultaneously shift where we want to be into this dimension and this dimension into another unknown dimension causing a cascading effect. Much like a rubix cube you'd have to shift one plane into another and others around it to leave no space unoccupied to prevent chaos.
