Re: Creates more problems than it solves?
Yes, estimated. But in km/s? That was clever :-)Hopefully the smiley means you are just being a smart-arse :-)
Roemer never made the estimate in Earth-based measure; the conversion to km/s is so the modern reader can comprehend and compare. Huygens' estimate for example was a value of 110,000,000 toises per second, an amount incomprehensible to most people today (possibly when it was made, too). At El Reg it really should be percentage of maximum velocity of sheep in a vacuum, but I couldn't be arsed to work it out.
