What is the relation between light years and people years?
Light-year is a physical measurement related to Universe Issues, and it comprises huge distances across the Universe. People's years is a measurement related to the lifespan, not only for humans but also for all living creatures. The difference is that People years is a measure only related to life, while light-years is not. The point is that a light year is a measure of distance NOT time. It does get people confused sometimes. It's how far light goes in a year.
How many years are in a 100 light years?
Years are a measurement of time; light years are a measurement of distance. A light year is the distance light travels in one year (in a vacuum).
Why were light years created?
Light years is a measurement of length (not time!), and was taken to use for the purpose of illustrating the wast distances in the galaxy and the universe. One light year is the distance in which light will travel during one year at the speed of Light ~3*10^8 m/s.
Are light-years stars?
No. A light-year is a measurement. A light year is a distance measurement based on how far light travels in a year.
What is the measurement of distance in space?
Light Years

How are the distances in the universe measures?
In 'light years' or in 'scientific notation'
How big is the universe 9898754364575272657277777777777777777777777777777777777777777777772222222222222222222222222222222222222222222222222222222222 years ago?
That was before the whole expansion started, so 0 miles or any other measurement in volume. The Universe is only about 13 billion years old.
