It sounds confusing for a layman but "light year" is not a unit of time. Hence, it makes no sense to compare it to a year. It should be compared wi A light year is a measure of distance. He may have resisted expressing distances in light-years because it would reduce the accuracy of his parallax data due to multiplying with the uncertain parameter of the speed of light. No matter how much time passes, there will forever be limits on the objects we can observe and the objects that we can potentially reach.
