A light-year is a measure of distance, not time. A light-year is the distance traveled by light in the span of a year. Light travels at 186,000 miles per second, do just do the math. How many seconds are there in a year x 186,000 miles...

Light years are actually a measure of distance, not time. A light year is the distance light travels in one year.

A light year is the distance that light travels in a vacuum in an earth year (365 days). At 186,000 miles per second and 31,536,000 seconds in a year, light travels 5,865,696,000,000 miles (almost 6 trillion miles)!

A light year is actually a measure of distance, not time. It is the distance that light travels in a vacuum in one earth year, baring the effect of gravity, particle collision and other outside factors.

Simple. The term "light year" is stupid for it does not refer to time even though the word "year" is in it. It's really just a fancy way of saying "so many miles/kilom's per hour/day/month". "Light years" refers to distances, not time zones. So it matters not if the earth is 6,000 or 6 million years old, the distances between stars will always be there, in approximate estimates, for stars do move around a little bit.

Please tell me you're joking...
A light year is not a measurement of time - it is the amount of distance travelled BY light in one year.
