Instead of trying to picture two straight parallel conductors of infinite length or a cesium-133 atom vacillating between two hyperfine levels of its ground state, just remember this: The fundamental SI units are based on immutable properties of the universe, and they are mutually independent. All...
throughout the universe. We know this because we see it concentrated within galaxies and absent in the gaps between galaxies. However, when we talk about the density of matter in the universe, we're imagining spreading everyatomin the universe (three-quarters of which are hydrogen) evenly ...
