Lifted!! The Doppler Effect


20090613214727

.….More or less, that is the Doppler Effect, most famously used to come to the conclusion that the universe is expanding, since no matter which way a radar is pointing, it detects a redshift, the visual manifestation of wavelengths bouncing off a receding source. That had been a surprise: the universe, in every direction, was leaving us (and apparently looking beige while doing so.) I’m not sure if it’s wrong or silly to feel more sad and lonely on account of such facts like the universe’s expansion, but somehow I do feel that way….
