“A mass cultural delusion that the sun’s apparent position to arbitrarily defined constellations at the date of your birth somehow affects your personality.”
– Sheldon Cooper (The Big Bang Theory)
And to be honest what he said is completely true. Astrology is nothing but complete bullcrap. Their claims have no scientific evidence. So you might as well stop asking whether it is true or not. It just simply isn’t. In fact your zodiac is no longer true due to a phenomena known as procession. Spinning tops are one example. They spin around an axis. Now when you first start rotating them. They rotate around themselves, but not for a long time. Soon the axis will tilt and start rotating around it is previous position, It is a bit hard to describe, you might as well watch the video:
Can you see how they no longer keep rotating the same way ? The same thing happens with the earth’s axis. That means that the constellation in which the sun is in will change. Since the zodiacs were made long time ago I can assure you they’ve changed.
BOTTOM LINE: Astrology is crap.
