Why is distance in Space measured in lightyears?
In: 1
Space is so enormous that you need a very large unit to measure it. Light, as far as we know, is the fastest thing in the universe, so the distance it travels in one year’s time makes for a consistent and easy to contextualize measurement.
Like, to put it into context, one lightyear is around nine and a half trillion kilometers. that’s almost incomprehensibly large, and even then we are measuring some distant stars and galaxies in millions or even billions of lightyears.
