If area measures 2D space and volume measures 3D space, what

hyper-volume

There isn't 4D space

This.

time obviously... are you slow on the uptake?

Oh, well.

Shucks.

A totally antisymmetrized tensor product of the four 1-forms that span the tangent vector space.

It's called a "volume form" for any dimension, if that's what you're asking. And it's unique up to a multiplicative factor.

Measure the space needed for the 4d opbject to exist in. A circle around an 2d image of a 4d object would translate to a 3d sphere that has the volume to contain an 4d object.

4d is meassured in circles
