Scientific proof Zodiac signs not real

I REALIZE that this is a tv show. But what Sheldon's saying is accurate.
But is there any proof that Zodiac signs are true/false?

Please USE science/mathematics as proof.

Wow.
Epic failure to think.
Perhaps, despite the evidence to the contrary, you have the capacity to think.
Proof is, by definition, evidence sufficient to convince.
If you are convinced, anything or nothing is sufficient.
If you are convinced of the contrary (or negation), then no amount of evidence will be sufficient.
Your use of the word "proof" is retarded, in case I haven't made myself clear.
Scientist use the term "evidence" and couch conclusions in terms of probabilities. If you are searching for absolute truths, science can not, and will not, deliver them -- go look in religion or philosophy. Unfortunately Yahoo puts paranormal and alternative "studies" under science. If I were in charge, they would be horsewhipped and sterilized for it. But I meander...

How can a sign be true or false? Is a coca-cola sign true? Are you really that inarticulate or unable to think?

The Zodiac is a set of constellations which have been named. They exist.
There is plenty of proof that they exist. (In this case, I use the word proof, since you would have to have a nut loose to not agree that they exist...now whether they are Suns or just patterns of lights in the sky is a different matter....)

If you are asking about astrology. Then ask. It is not a science. It is not coherent. It is not capable of predicting behavior, personality, or the future with accuracy above chance.

Zodiac signs are part of the history of astronomy. In ancient times, the sky was divided into 12 zones, each zone named after a constellation on or near the celestial equator. Each zone was 30 degrees of longitude wide, and extended from the celestial north pole to the celestial south pole. The first day of spring coincided with the sun entering Aries.
