I'm glad to have a response, because I've Googled for discussion in science circles, and brought the matter up elsewhere, and no-one seems to have noticed the implications, or answered me. After almost 20 years, you'd think someone would say 'heeeyyyyyy...??!'.
I'd like to examine the experimental side for a moment, not the theoretical. Would the non-differential (after very long distances and time, and taking into account the different production mechanisms) in the arrival of light and neutrinos from supernova 1987a constitute strong experimental...
I hope I don't understand the subtle point: that you guys send newbies to another forum to look for a left-handed tensor. :cry:
Google "c speed of light constant definition" and examine the variety of loose and formalist treatments of the 'meaning' of 'c', and that will have to suffice for...
I don't see where I said or implied 'measurement'. I used the term 'constancy' three times. Using light to define the measure of a metre is a convention. If I recall, it was formerly defined as 1/10^6 of the distance from...
...but enough of that; let's salvage the rest of my query...

I think you mean exactly 299,792,458 metres per second, by definition, in vacuo.
I appreciate constancy in Einsteinian relativity. But there are variant relativities, and Majuiro (sp?), et al have challenged this fundamental idea of constancy.
I'd like to examine the experimental side for...
Variable c, neutrinos, 1987a
Hi,
I'm not sure the proper way to start new questions, but if some people could answer this one, and tell me how to, I hope that's OK.
If (if!) c were variable over time because of changing permitivity/ permeability, or because of changing free-space energy...
