I'm being curious and I'm struggling hard to find a reliable answer on the internet, so here is my problem. What is the TOTAL margin of error in our current knowledge/measurement of the speed of light?
Wikipedia only partially answers on the following article:
Several limiting factors are listed, but only a few of them are given numeric values, and I suspect there may be more limiting factors, non-listed in the article.
I'm interested in the numbers as well as in their explanations.
[spoiler]Obviously, don't express your answer in metters, as the metter is defined by the speed of light. Instead, you can use as a length unit things like the wenglenth of a laser, the Planck's length, or a simple percentage (as in "±1%").[/spoiler]
