The distance between objects in the universe are usually measured in light years because _________________.
many objects in the universe are in close proximity to Earth
only electromagnetic waves, such as light, can travel through a vacuum
smaller units, such as kilometers, result in values that are impractical and large
many objects in the universe radiate light that can be seen from Earth
