Light years is actually a measure of distance expressed in time. For example, a galaxy is 1 light year long, which means it will take 1 year to reach that galaxy with the speed of light(c). This implies that the galaxy is c(m/year)*1 meters long.
No, 'years' is a measure of time and 'light years' is a measure of distance.
Zero. Light years are a measure of distance, not time.
None. A light year is a measure of distance, not of time.

A light year is a measure of distance, not time. It is the distance light travels in a year.
They don't. Light years are a distance measurement, not a time measurement.
None. A light year is a measure of distance, not of time.
587 light years is a unit of distance, not time. It represents the distance that light travels in 587 years.
In spite of its name, a light year does not indicate time, but it indicates distance! It actually equates to the distance that light travels in one Earth year, which is a very big distance, seeing that light travels at 186,000 miles per second.
Light years are used to measure the great distances of space. One light year is about 5.86 trillion miles. This is the distance light travels in one year's time.
A light year is a unit of distance, not time. It represents the distance that light travels in one year. So 6300 light years is the distance that light would travel in 6300 years on Earth.
One light year is the distance light travels in one Earth year. So, 70,000 light years would be equivalent to 70,000 Earth years.
