Does a transformation of dimensionless complex Minkowski coordinates to quaternions lead to a new cosmology?

Dimensionless complex Minkowski coordinates u are given as: u=t+i*(x,y,z); The Minkowski coordinates in legth units are given as: U=t*cT0+i*R*(x,y,z); R is a very large length, T0 is an arbitrary...
