This uses Jean Meeus' approximation of Simon Newcomb's analytical method for determining the sun's position. Measuring the position of the sun within the CFHT cloudcam images reveals that the sun is precisely where it should be in those images.

Pardon my ignorance Dr. Astro, Is the Sun traveling in space revolving around the center of our Galaxy? If so do we know the speed? Is it moving out from center of Galaxy? Thanks for any information. |

I'm not sure if there really is a Nibiru, but one thing is for sure, I believe something will cause great meteors to pound this planet sometime late in the century 2085-92, whether that will be a planet is debatable, but something will cause great destruction from "stars falling from the sky" The above hypothesis was formed from evidence (physical) that I witnessed as a young boy, backing the plagues as described in the Holy Bible in Revelation. |

Captain Spaulding User ID: 39290457 United States 05/08/2013 11:15 AM Report Abusive Post Report Copyright Violation | Get a YESWATCH. I have the Zulu design. I can sit in a dark room anytime of the day or night and tell you exactly where the sun and/or moon are any time of the day or night with just a glance. You can tell how many hours of daylight or dark are left. It displays sunrise, sunset, solar noon, the same with the moon and it's phase(s). It has an alarm that you can turn on to sound off 1/2 hour before and then at sunrise and 1/2 hour before, then at sunset. It also displays the equinox's, solstices and cross quarters. Nothing complicated about it. All at just a glance. Plus all the other bells and whistles like countdown timers and alarms and can calculate using algorithms the sun and moon positions for 600 cities around the world any day for 99 years. I haven't tried that though. Yeswatch. The Zulu (named after the prime meridian, or GMT). Cool as hell. Made in America by a great company. I DO NOT HAVE ANY AFFILIATION WITH THEM OTHER THAN OWNING ONE OF THEIR WATCHES FROM THE ZULU COLLECTION. |

Dr. Astro (OP) Senior Forum Moderator User ID: 33360181 United States 05/08/2013 12:27 PM Report Abusive Post Report Copyright Violation | Quoting: Anonymous Coward 39510024 It's wrong. The solar system is not a "vortex." Planets do not trail behind the sun as it travels through the galaxy the way that model describes (best seen at the start of his follow-up video: [link to www.youtube.com] ). The solar apex, our solar system's direction of travel relative to the local stars, projected onto the sky has the coordinates of about 18hr RA, +30 degrees Dec ( [link to books.google.com] ) whereas our north ecliptic pole has coordinates of about 18hr RA, +66.5 degrees Dec. [link to en.wikipedia.org] Even if you consider the motion of the local standard of rest within the arms of our galaxy ( [link to www.gb.nrao.edu] ) we are still not moving towards the ecliptic pole and we are still ahead of our sun at certain times of the year. In the latter case the vector of our direction of travel points to about 20h 57m, +47d 53' which is separated from our ecliptic pole by about 30 degrees and places us ahead of the sun relative to its direction of travel in August, whereas in the former reference frame we're ahead of the sun when the sun's position along the ecliptic in our sky is at 6hr RA at the June solstice. The "helical" model is in direct contradiction to simple empirical evidence. Were it true, Newcomb's own data and calculations on the position of the sun as seen from earth would not work.

As such, the perturbation calculated would mean changes so slight to Earth we can not measure them w/o sophisticated equipment. As gravity is infinite in its reach across the cosmos, the effect on Earth is real. Very small and nothing to be concerned over, but it IS there. One day, ONE DAY, something big is going to fly past us. It is only a matter of time. Until then, people are gonna doom no matter what. When the real deal flies by, people will say, "See, I was right". But a broken clock is right twice a day. In other words, every prediction comes true eventually. We are all prophets who are blind to date calculation . Rant over, lol |
