Well, in reality 1 means a natural dimensionless number. Having no units says, that c is unitless and has only the numerical value 1. Since it assumed to be measured in 'natural units' (called 'nu' here), these nu have to cancel out, because nu would also have to have dimensions (because ALL physical quantities have numerical value and dimension). Since c=1=nu/nu these 'nu' things must be equal in dimensions and numerical value. But we know also, that c ~= 300.000 km/s The assumption is: 300.000 km/s =c =1 But, how do we get rid of the dimensions 'length' and 'time' in the usual speed of light measure? This would require : 300000 km/s =1 hence 1nu=300.000 km =1 s = 1nu hence: c*t=1 nu That would define 'nu'. But this is not allowed, because that would be a 'circular definition', because c is already based on nu. ... TH
