Guys remember when taking about lightyears it's discussing the distance traveled for
one year at the speed of light..Speed of light is about670,616,629 mph ( 186,282 miles PER SECOND)
1 lightyear is around 5,880,000,000,000 miles.(trillion)
So if something is 13 billion light years away...that means
13,000,000,000 Times 5,880,000,000,000
74,440,000,000,000,000,000,000 miles
