Sylvester started as a beautiful nowhere in 1893 and was first called Isabella Station. When the Brunswick and Albany Railroad came through southwest Georgia, the county seat was Isabella, which is located three miles north of the railroad.
It really is an incredibly long distance -- a lightyear is roughly 6 trillion miles or nearly 10 trillion kilometers. Here's how you calculate it. You start with the speed of light, which is about 186,000 miles per second. Then you multiply that by 3,600 seconds in an hour. Then you multiply that by 24 hours in a day.
A light year is a unit of distance. It is the distance that light can travel in a year's time which is six trillion miles. Light moves at a velocity of roughly 300,000 kilometers in every second. So in one year, it can travel roughly about 10 trillion km. One light-year is equivalent to 9,500,000,000,000 kilometers.
