0 the distance that light travels in one year (about 9.5 million million kilometres) --
1 the great distance that light travels in one year; about 5,880,000,000,000 miles or 9,460,000,000,000 kilometers --
Our standards of training are already light years ahead of those in almost every private security company.
Their results indicate that the bar is 27 000 light years long.
However, if the player happened to find a system 655.36 to 670.36 light years away, it would be counted by the game as within the 15 light year range.
If this acceleration were to continue forever at its present rate, our descendants could devour only the region currently within about 10 billion light years.
Partly for this reason, it is still the unit preferred in astronomy and astrophysics, though the light year remains prominent in popular science texts and more everyday usage.
The nearest other intelligent life form must be roughly 10 billion light years away.
The distance to this star has been measured directly using the parallax method, which places it away with a margin of error of about a light year.
This is equivalent to moving a distance of one light year every 14,700 years.
