Our world we live in is a subset of spacetime under the condition, that 
time is local and all places have their own local time.

We would need to 'integrate' our own world into hyperspace and try to 
estimate, how the superset 'spacetime' to our observable world is 
composed, by testing, which superset would look like our observable world.

I had the idea, that (local) time would be best described by an 
imaginary number and the axes of euclidean space by real numbers.

This could be a certain kind of a quaternion, which needs imaginary 
numbers in the scalar part.

Such quaternions are called 'Bi-quaternions', which can have complex 
numbers in all four positions.


Now we are as observers somewhere, where time is locally an imaginary 
number, hence the axes of space are reals.

This is how our local environment looks like and as were are also 
observers and somehow here, we could assume, the superset to our world 
(which is also called 'spacetime') is built from Bi-quaternions.

In a way, that would be a 'mathematical superspace', sure.

Don't know, whether or not this is satisfying, but I cannot change that 
anyhow.
