In Minkowski 4-D spacetime the cooridnates of an point are (ct,x,y,z).
My question is why we multiply time with speed of light c and not some other speed v (speed of object moving in three spatial dimantions)? If we treat the time as a fourth dimension it would be more reasonable to say that (t,x,y,z) and not (ct,x,y,z).
