Anyone who thinks they can learn science from a so-called bible study
deserves what they get .. fairytales and nonsense.

As far as I know Isaac Beeckman, in 1629 was the first to propose this
experiment.

Sounds like you've been VERY bibulous lately.

I doubt that! However, you may have picked that up from a group that
is called "Creationists":

However, there is a more serious discussion going on, see here:

How would you measure it? A practical complication is that nowadays
the speed of light is used as reference for length...

Why not? Why would such things remain the same?

The speed of light is c = # meters/second. Suppose that # = 1, and
the speed of light decreases by 50%. By the rule of Physics cited by
David, instead of this being measured as c = .5 meters/sec, the meter
rod would become half as long as it was so c = # meters/second remains
a constant regardless of the actual speed of light!
That sounds like a lousy choice, to me.
