What is your problem, man?

I'm asking whether other people have seen or calculated the same value.
I'm not interessted in the *defined* value, I'm interessted in the real and exact value of the speed of light! Because other calculations depend
on the exactness of this value!
Do you have difficulties to see the difference?


Historically the speed of light was measured by many investigators more
and more accurately until somebody said, "this is a fundamental constant
of nature--instead of measuring it with our meters, we can define our
meters in terms of the speed of light".

If the speed of light were varying, that would show up in countless
precise measurements and tools such as GPS.

The real exact value of the speed of light is represented by c. In
defining it in terms of m/s we redefined meters to be in accordance
with c.
