i think that in the end you will find that, while there are many dimensions, they are constructs of the human mind. by this i mean that in the grand scheme of things, it is impossible to tell the difference between the 1st and the 8th dimension. it is our human obsession to categorize and compartmentalize which has led us to the conclusion that time even exists in a linear form. this is a distinct attempt by us to understand our surroundings by observing physical phenomenon, which is inherently dangerous because the simple act of observing a phenomenon can and often does change its behavior.
