The claim, supposedly by NASA, that the zodiac has shifted, which is popping up everywhere in the Internet lately, is a genetic fallacy. It refers to the prehistoric common ancestor of astrology and astronomy and it claims that the frame of reference used by the astronomy branch is what the (tropical) astrology branch should have followed. It is not a scientific argument because it does not present any comparative data or practical evidence to support the claim. It is an unverified hypothesis, or more correctly, a false rumor. No scientist at NASA would knowingly accept a genetic fallacy over evidence.
