   The word 'dimension' has different meanings, hence it is necessary to   
   write, which meaning was meant.   
      
   If we refer to space, the 'usual' space has three dimensions of the type   
   'length', which are orthogonal towards each other.   
      
   This wouldn't allow an additional orthogonal dimension of space for time.   
      
   So, we need a different meaning for 'dimension' and a different 'space'.   
      
   If we add t to the 'x,y,z-space' we end up in what is called spacetime.   
      
   But I would suggest a different approach and use complex numbers and   
   assume, that time is imaginary and the dimensions of space real.   
      
   An even better approach would be to use a construct called   
   'biquaternions' and assume, that the 'real space' has actually such   
   features, as if it was a quaternion-field, where points have the   
   features of bi-quaternions.   
      
   This would allow three imaginary axes of time and three real axes of   
   space, plus two additional 'dimensions' for scalars and pseudo-scalars.   
      
   I have written a kind of book about this idea some years ago, which can   
   be found here:
