Ha!
Do you really think the average human is capable of, and interested in, observing the speed of light with any accuracy?
About 15% are capable of, and maybe 1% are interested in.
Where do you (not) fall in the spectrum?
What percentage of the world's population is using microwaves and chocolate to make such observations? Are EMP's the be-all and end-all of scientific measurements?
As a guess about 0.7% use chocolate and the other 0.3% use cheese. And that's EMR (electro-magnetic radiation), it's not the end-all of scientific measurements.
Just one of the ways to measure the speed of light.
Good grief. Why not try the cutting edge some day instead of sticking yourself into Hersheyville?
Such as what, Nestles?
Or is dark all that matters?
Oh no. They have white chocolate too ...
We're talking chocolate, not fudge.
