If you "actually" knew what you were talking about, you'd already know that "go to" scopes calibrate alignment by the stars' relationship to one another which is independent of how high or low they happen to appear in the sky in relation to the northern or southern horizon of planet earth, which is really at issue here. How many amateur astronomers actually take the time to notice or calculate the inclination of star locations over time?  Take our Moon for instance...gee whiz, is it supposed to play rodeo all over the sky in two weeks time, covering many degrees of latitude that quickly?  Really?  Hmmm, the answers must be somewhere....

The fact is, a non disclosure regulation, prohibiting professionals from speaking about these things upon pain of summary dismissal from their jobs or worse, has been in force for some time now, not long after the huge earthquake and resulting tsunami of 2004.  Also, it wasn't long after that time that the U.S. government publicly abandoned celestial time for atomic time.  Anyone who watches the sky...AT ALL....with any degree of intelligence can see PLAINLY that Earth is wobbling greatly.

Proof is everywhere and, sadly, most refuse to employ their senses in favor of a cursory google search.

If google is your oracle, then the greeks have borne you gifts indeed.

Don't believe everything you read.  D-I-G.
