Light year
It is a unit of measurement used for large and very long distances, such as the distance between the Earth and the stars. A light year is defined as the distance light travels in one year
The speed of light is 300,000 kilometers per second, and if we say that a planet is one light year away from us, that is, 9.4 trillion kilometers away from us.
If we say, for example (that Ahmed lived 12 light years)
This question is wrong and incorrect
And the more accurate expression is that Ahmed (walked 12 years at the speed of light) and this is not scientifically possible..
There is no term called (light year).
It is just a unit of measurement for the difference in distances between stars
Earth year (regular)
It is used to measure time and periods of human life
A light year is a unit of measurement for the vast distances between stars
