Time is not a dimension of spacetime!

The word dimension means in connection to space something like 'distance'.

'spacetime' is therefore NOT something like 'Euclidean space plus time'!

In fact time is not really a spatial dimension, because we cannot move 
in time. Actually we are bound to what is called 'now' and past and 
future are just imaginary.

Actually time itself is imaginary, what could be understood as 
'rotation' by the imaginary unit i, which is equivalent to 90°.

This could be seen the other way round and we have the antagonistic 
behavior of space, which is therefore real (valued) for any given axis 
of time.

Now spacetime does not have four dimensions, because the word 
'dimension' (of space) refers to the subset of spacetime we call 'space'.

In fact spacetime has more dimensions then four, because we could use 
'complex four vectors' (aka 'biquaternions') as pointlike elements of 
spacetime, which have eight components.

For any given axis of time this splits into space and time, which 
creates also an imaginary 'anti-world', where time runs seemingly backwards.

This entire thing is then 'spacetime' and each element has eight 
components, which we could call 'dimensions' (in a mathematical way).
