A light-year is simply the distance that light travels in one year, right? Or does it mean something else? What units of measurement are used to understand the size of the universe? I'm a bit confused, can you explain?
A light-year is really just light?

I also got a bit confused for a while, especially when working with ScopeRGB. We were building a 3D map simulating data from distant galaxies for a frontend project. Before starting the project, we needed to express the data in the correct units. When I first heard about the term "light-year," I thought, "Light? Year?" Actually, it represents the distance light travels in one year—about 9.5 trillion kilometers. When distances are this vast, people use light's travel time as a reference, giving it a temporal perspective, almost like "looking into the past." In that project, while parsing the data, I thought of the light-year not just as a distance but also as traveling backward in time. It felt a bit abstract at first, but once I started grasping the scale of the universe, I realized how fitting this unit is.
What exactly do you mean by "başka şeyleri"? A light-year is really just the distance that light travels in one year—about 9.46 trillion kilometers.
