Extra Dimensions Beyond What?

[r6r6]

There is XYZ catesian dimensions of XYX with, depth and height.

Then there is dimension of time{ t } ergo XYZ and t.

Any talk of hyper-dimennsions begins with the volumetric diagonal from the corner of a cube i.e. XYZ becomes abc and d is the diagonal from corner of cube where XYZ aka abc meet.

For my part, the only other dimensions are those that are beyond our ability to quantise if not also quantify, and that we know of to exist indirectly.

Ex ultra-micro gravity ( ) { force }

ultra-micro dark energy )( { force }

Virutal particles{ ? }

Dark Matter{ ? }

Inflaton{ that which is force alledged to exist during the alledged inflationary theory of Universe }.

Any others I left out?
