I suspect any confusion was that many think it would take 100,000 years at the speed of light to cross the Milky Way. My intent was to point out it takes much less time. 12 years to cross and I did later add 24 if you want to stop (and live). 12 years, 24 years or 100 years, the point was made.That wasn't made obvious. More than one person was confused by it his assertion. It has been cleared up now.
D H also makes some good points about good manners in these forums. Unless you have the credentials of Einstein, Your opinion is just that, an opinion. Your presentation when disagreeing with some one says it all.
