Hi all,
According to this site : http://physics.nist.gov/cuu/Constants/, the speed of light in vacuum is [tex]299792458 \frac{m}{s}[/tex] with no uncertainty! How is that that there's no uncertainty? I like this website because it gives many physics constants with their uncertainties, but here I have to say that I'm septic.
