Obviously we can't seem to detect 100% redshift of c, so I'd doubt -c being detectable. Supposedly our universe radii is getting another ly larger per year, and as such it's undetectable. ~ BG

Can we detect a blueshift of c? ~ BG

In that case it should be easy to objectively prove. So why hasn't it been proven? ~ BG
