'physical' means 'somehow observable'.

But that means only a certain subset of reality, which is in the 
observable realm.

Now we need to find a super-set of our reality, which behaves similar to 
our observable world, if we apply certain plausible 'visibility conditions'.

I found such a superset and called that 'spacetime'.

Matter in this view is a sub-set of spacetime and what I call 'timelike 
stable patterns' (in 'structured spacetime).

The imaginary parts of complex numbers are actually real.

this is quite astonishing, but imho true.

So our universe was assumed (by me) to function similar to a field of 
'bi-quaternions', which are connected in a certain way, that you may 
call 'rotations'.

This is a certain multiplicative 'sideways' connection of pointlike 
'elements of spacetime' .

In case you are interested, you could read my 'book':
