The Science of Zodiac Signs and Mercury Retrograde Explained.

The positions of the stars in the zodiac have changed since the Babylonians mapped them over 2,000 years ago, not because the stars themselves have moved around, but because Earth's view of them has changed due to precession. This means that over time humans are seeing a shifted night sky, marching forward from our ancestors. Each age is associated with a specific constellation that the Earth's tilt is pointing toward at that time. Mercury retrograde is a real scientific thing and it's happening right now.
