Actually 'space' in the sense of 'outer space' or 'universe' is not real.

What we see in the night sky is 'stacked in time' and the further away 
the longer ago.

So: what you call 'space' does not exist in the first place, because 
what we see is a picture from the past.

This is commonly called 'past light cone' and that is based on our 
current position and us as human observers.

Now what we see must belong to something, which is also kind of space, 
but in most parts invisible.

Since 'our space' is obviously a subspace of some other space, which is 
mostly invisible, and our space has three dimensions, that superspace 
could have more than three dimensons, from we have access to only three.

Now we need to find a hypothetical superspace, to which our observable 
space could be a subset.

This is in fact possible and with some sort of mathematical precision, 
if we take spacetime of GR as real, but with slightly different features 
and a different type of math.

This type of math is already known.

I had assumed it would be a clifford algebra called CL_3, where 
pointlike elements behave like bi-quaternions.

(But now I'm considering a slightly different type called 
'dual-quaternions'.)

That is, of course, just a guess.

But guesses are actually the only way we could possibly find out, how 
such a superset could function, because we have access only to the 
subset, that you called 'space'.
