news to me, but i come and go into astronomy cycle thru interests currently not interested much. but i dont feel they can just change the signs. that is like just changing the name of a star. i think what might be is someone writing the articles are confused about how the north star will change to vega in the future and then the constellations that fall on the zodiac will not be the same/shift but by that time no one around today will be here, earth might not even be here. anyway do go by me i did not research it just from my knowlege, what little is it. sigh....
