Your apologies are acknowledged, thank you. Unfortunately, we have to leave it at that.
Sorry Domenico, I meant no offence.
We aren't in the habit of being very formal here and I've always heard adult guys from several southern regions calling each other guagliò in a friendly manner, even in address to a cool guy who's tough and knows his stuff, like. Of course I wouldn't have used it if I was addressing you as Lei and Sig. Idato, but I've always regarded it as a friendly chum kind of a thing that has spread around a bit up here too. Despite several old acquaintances, there's nothing specifically Calabrian I could think of.
I adhere to the school of thought where mass is just one kind of energy, called rest energy. To better clarify, I do not use the archaic notion of "relativistic mass" which has caused so much confusion since 1905.
Now let's get to the dispute: the relation of [imath]C[/imath] with [imath]c[/imath]. If we compare:
[math]E=mc^2[/math] and [math]E=mC^2[/math]
we can divide by the scalar [imath]m[/imath] in both cases. If [imath]E[/imath] and [imath]m[/imath] are the same in both cases, then by the transitive property of equality we can say that the two squared factors equal each other:
If both [imath]C[/imath] and [imath]c[/imath] are numbers they can differ at the most by sign. Now [imath]c[/imath] is the usual familiar one so, either your [imath]C[/imath] is [imath]-c[/imath] or else it must be something for which some kind of square is defined: a norm squared for instance or a scalar product of [imath]C[/imath] with itself, perhaps even the self contraction of a tensor...
So, is your drift anything of the above type? In any case, does it have any relation to VSL and PV?
