Re: Creates more problems than it solves?

The metre was invented on 17 March 1791. Ole Roemer estimated the speed of light at 200,000 km/s in 1675 and James Bradley gave the number 301,000 km/s in 1728.

So the kilometre was used for measurements 84 years before the metre was invented? This relativity business truly is weird.
