WebHow do we know that we live in an expanding universe? As pictured above, the wave-length of light is longer when it is red-shifted, and shorter when it is blue-shifted. When moving away, the light is more stretched out (causing red-shift), when moving towards us, it is compressed (causing blue-shift).
