Question about winter solstice
On 3 Jan, 19:48, wrote:
Hello group, I was kinda pondering this question in my mind for a while, but I hope someone learned here can put this to rest for me Due to precession of the equinox (I think somewhat of 50 arcseconds per year?) the first point of aries always goes backwards on the ecliptic. So now I'm thinking does that mean that the winter solstice will fall in a different month from December if we travelled many hundreds or few thousands of years either backwards or forward in time? In our times, it seems to be on December 21st/22nd every year, but would this have been the case say around 5,000 BC when the pyramids were being built? Does our calendar year (Jan-Dec) always mean summer solstice will ALWAYS be in June and winter solstice ALWAYS in December? Well I sure would appreciate your correction for me non-expert! There is a tropical year and a sideral year. You are right, because of precession the two are not the same. A calander year is TROPICAL, that is to say the solistice is June 21/22 and Dec 21/22. Leap etc. yesrs are put in to ensure this happens accurately. http://en.wikipedia.org/wiki/Tropical_year http://en.wikipedia.org/wiki/Sidereal_year The sideral year is different because of precession. The sideral year is the true time for a revolution round the Sun. Jan 4th is the closest approach to the Sun. Alice Springs receives more solar energy then than Saudi does on July 4th. 13,000 years ago Saudi received more energy. When the Pyramids were built star signs were different (about 3 months) but the seasons were not as we reckon in tropical years. BTW - Horoscopes are now 1 month out. They have not been revised in 2,000 years. - Ian Parker |

Question about winter solstice
In uk.sci.astronomy message , Sat, 3 Jan
2009 17:26:43, Ralph posted: if you used our present calendar, which was modified in 1583 to the tune of 11 days under pope Gregory. The present calendar was decreed (by Pope Gregory XIII) and commenced (in places) in 1582, with 10 dates being then omitted. Those making the change in March 1700 to February 1800 would have omitted 11 days; in 1800-1900, 12 days. But Alaska simultaneously moved from longitude 210 East to 150 West, thereby omitting 11 dates and having two consecutive days being Friday with dates differing by 12 days. As a neighbour of Alaska, can you confirm that the jump was 1867/10/06 to 1867-10-18? -- (c) John Stockton, nr London, UK. Turnpike v6.05. Web URL:http://www.merlyn.demon.co.uk/ - w.

You got that backwards,the calendar system drifts against the seasons and that is why the 24 hour day is added every 4th year to reset the annual cycle to the human devised 24 hour day cycle and its 365/366 day calendar outrigger. Adding an extra 24 hour day every 4th year (except three out of four of every 100th year) is *part* of the (human devised) calendar system, which avoids drifting against the seasons by doing so.

Yep, about that. the first point of aries always goes backwards on the ecliptic. So now I'm thinking does that mean that the winter solstice will fall in a different month from December if we travelled many hundreds or few thousands of years either backwards or forward in time? No, because the year is ultimately anchored to the first point of Aries. *As the first point of Aries slidles along the ecliptic, January 1st slides the same amount. *Thus, the months do not change relative to the solstices and equinoxes, but the constellations visible in the sky at those times do change. -- Dave Great! So Christmas will always fall within a few days from the winter solstice, indefinitely, right? If the Gregorian calendar was fixed as late as 1582, how can we be certain the birth of Christ fell on December 25th going back to 0 AD? Is it an extrapolation of the Gregorian calendar going back to that time that scientists have determined? The other thing is the Earth being at perihelion on January 4th every year. That must again stay FIXED at around this date froever, because last I checked the orbital elements of the Earth, the longitude of perihelion does not change more than 0.0001 degrees per century. cheers all for your thoughtful and very elaborate answers! |

Christmas is celebrated on December 25 to compete with the pagan festival of the Saturnalia, celebrated just past the winter solstice. John Savard Define "Christ". Clearly, some dude never existed who turned water into wine (sans viticulture), raised a guy from the dead, and converted 2 fishes and 5 loaves of bread into a spread for 5000 hungry people, or made a lame guy walk. So that one never was. Based on that, IMO we can safely say that the biblical Jesus never existed. So the whole thing falls apart, revealed for the wicked, mendacious Sunday school lie, designed to subdue children, that it always was, and was designed to be. Fight it: It's a big LIE, and more people have died as a result of it than would've died if some evil agant had never dreamed up the whole story. Look at these fools in England fighting over whether women should be allowed to become bishops! You couldn't make this stuff up! "Love thy neighbour" - but bitch and whine about thy female neighbour wanting to spread "God"'s word! Hypocrite, pious, chest-beating pharisees, all of them. There are so many sects and divisions in the Christian church that it's laughable, given that they're all supposedly pushing the same loving "god". The irony is, well, my irony meter is pegged and smoking. Christians' stupidity is the most majestic and impressive feature of the whole issue. I remember being forced, with my sister, to attend church and Sunday school every Sunday morning, and after the service, the congregation would mill around in St. Luke's (Rochester) church hall. And gossip. And bitch about each other. In "god's house"! For ****'s sake, what were these people doing? What was a child to think of what it saw and heard there? These people, by the definition of their own teachings, were the worst kind of sinners! I still can't believe what went on! And I was supposed to buy into that?

Based on that, IMO we can safely say that the biblical Jesus never existed. We can say with certainty that the stories about Jesus found in the New Testament are at least somewhat inaccurate. And we can say that there is essentially no historical evidence that such a person actually existed. But we can't safely say that the character in the Bible isn't based on a real person. That question simply remains open, and may always remain so. Saying with certainty that Jesus never existed is as intellectually dishonest as saying with certainty that he did. _________________________________________________ Chris L Peterson Cloudbait Observatory http://www.cloudbait.com |
