month alignment with stars
Does earth has unique alignment with the stars every month for the past thousands (or millions?) of years? Or could there be a period when the alignment changes? |

Alignment requires a foreground reference, this dismal era justifies the orbital motion and position of the Earth using 'two sticks in the ground' references which are homocentric whereas the proper foreground reference is the central Sun. Your question is effectively meaningless unless you mean orientation instead of alignment - http://www.youtube.com/watch?v=hYqh72i2mhg |

It is always changing very slightly due to nutation and precession. The same mechanism that causes a spinning top to wobble around. http://en.wikipedia.org/wiki/Precession These days it is measured routinely with exquisite precision as a part of the VLBI network calibration amongst other things: http://www.iers.org/nn_10398/IERS/EN...tml?__nnn=true The precession period is ~26,000 years. Polaris will not be our north pole star forever but at the moment it is a very good approximation. -- Regards, Martin Brown |

Look who is giving instructions on the motions of the Earth,somebody who is part of a cult that can't manage to handle to cause of the day/night cycle !. The Earth has a second surface rotation to the central Sun apart from and in addition to daily rotation. A person standing at the North/South poles experiences this second rotation in isolation however all locations on the surface experience this second rotation just as the person at the poles does. Walk before you can run Brown and the same goes for all the other worthless empiricists that occupy this newsgroup,for everyone else they can immediately enjoy the spectacle of a planet with two surface rotations to the central Sun - http://hubblesite.org/newscenter/arc...99/11/video/b/ |

I remember that beautiful summer's day when I finally made the breakthrough as that insight was especially difficult to crack given that imaging on the internet wasn't the way it is now, Vivaldi called it the strife between harmony and invention as the spacial awareness to arrive at the conclusion is sorely challenged to its limits. The two surface rotations to the central Sun were easily discerned once I gained a foothold into the presence of the second surface rotation and it became a matter of finding just the right planet to put it into wider circulation - http://hubblesite.org/newscenter/arc...99/11/video/b/ You should be delighted,this is an insight that is not going to go away and there is so much to look at and enjoy when people get into the spirit of endeavor and the visual imaging that governs it all. |

... ... A person standing at the North/South poles experiences this second rotation in isolation ... A person standing at the North or South Pole, on a day when the sun is visible, will still experience the daily rotation, as he will see the sun appear to move in a circle across the sky over 24 hours. |

The second surface rotation is responsible for the year long orbital day/night cycle as a person standing at the South pole turns once to the central Sun as do all locations on the surface of the planet. Where is mixes at lower latitudes with daily rotation it is experienced as the seasons and variations in the natural noon cycle. When people take pride in the works of the astronomers who first provided the rough outlines for the motions of the planet then they will understand how to constantly add to a clearer picture of these motions that govern our physical existence. |

I was asking this because I'd like to know how the ancient astrologers plot the sky. For example. In the month of May which is the sign of Taurus in astrology. Did the sky orientation similar 5000 years ago compared to know? How many years is there changes such that Taurus month of May shift to July or something? Just want to know the astronomical nature of it and don't believe in zodiacs at all. |

The Zodiac is a convenient way for people to fix their position each year using the central Sun and the background stars and also the gauge the motion and position of the planets and moon in order to make sense of the structure of the solar system and especially our motion and position. You don't have to believe in the Zodiac because it is a random scattering of stars and the natural inclination of humans to see patterns. http://www.youtube.com/watch?v=eeQwYrfmvoQ Because the present day dunces try to run everything off a 'timeless' rotating celestial sphere so that they ignore the fact that the ground beneath their feet is moving,they fail to appreciate the annual motion of the stars the way the old genuine poetic astronomers knew them,people who really did take care to notice events in the celestial arena - "Canst thou bind the sweet influences of Pleiades, or loose the bands of Orion? Canst thou bring forth Mazzaroth in his season? or canst thou guide Arcturus with his sons? Knowest thou the ordinances of heaven? canst thou set the dominion thereof in the earth? " Book Of Job http://www.biblegateway.com/passage/...38&version=KJV The ancients took notice of the Sun's passage through the constellations which is why they discovered that the star Sirius misses a day after four cycles of 365 days thereby fixing not only the Earth's position in space but also the number of rotations it needs to complete a circuit. The author of the Book Of Job most certainly is referring to Sirius as 'Mazzaroth'. If we didn't add the extra day/rotation of Feb 29th,the Sun would appear to drift through the constellations very rapidly hence the extra rotation's worth of orbital motion keeps the year fixed to the first appearance of Sirius and to the Earth's orbital position in space to a reasonable degree of accuracy. Our ancestors noticed that there was an additional drift between the foreground Sun and the constellations which resulted in another required correction. The number of times the Earth turns,assuming rotation is constant, is slightly out of kilter with its orbital circuit above and beyond the leap day correction which keeps the Earth's orbital position fixed in space using rotations as a gauge. This is an intricate matter as the 'precession' is entirely a consequence of the slight mismatch between rotations and orbital circuits but has been corrected to a large extent by omitting a leap day in years ending in 00 which can be divided by 400. The main point you must take into account is explained in the YouTube graphic where the motions of the Earth and the apparent motion of the background stars against the foreground Sun is used as a gauge for the daily and annual motions of the Earth. These 'timeless sky' dunces of today have the constellations whirling about in daily stellar circumpolar motion and completely miss the point of the ancient use of the Zodiac in a proper way. |
