Next Year, An Asteroid Will Be Discovered
Apparently there's a hoax going around that asteroid "2014 AZ5" will
hit the Earth with devastating consequences. Of course, since this isn't 2014 yet, nobody's discovered an asteroid to which this name could be applied. John Savard |

Of course, since this isn't 2014 yet, nobody's discovered an asteroid to which this name could be applied. John Savard ========================================= It certainly is a hoax since it impossible to predict where the Earth will be to a precision within its own diameter a year from now. If you really want to start a hoax you should say "A team of scientists led by researchers from the University of [insert name here] have discovered [insert hoax here]". Only the gullible don't know the team of scientists are sophomore students and the researchers leading them is their professor, none of which want their name mentioned. Whatever, there has been a hoax going around that Algol is a double star since the huckster John Goodricke said it was in 1782, there has been a hoax going around that Einstein was a mathematician for over 100 years, why should you care about a hoax going around? As this is the first I've heard of az5, you started the hoax, Savard, by giving it a name. There's another hoax going around that the Easter Bunny lays chocolate eggs; I started that one. The main difference between your hoax and mine is that I deliver the evidence, chocolate eggs on sale every Easter. I'm telling you so before the event, there is no "I told you so" after the event with me. -- This message is brought to you from the keyboard of Lord Androcles, Zeroth Earl of Medway.

That statement was true 50 years ago, when we didn't know the length of the AU to better than 0.1%, but no longer. Our knowledge of the current position of the Earth is uncertain to a few meters. The uncertainty in is velocity is on the order of meters per year. Don't take my word for it. Download a bunch of planetary ephemeris files from ssd.jpl.nasa.gov, query them at a bunch of different times, and see how the position vectors compare as a function of time. The pairwise differences between files are certainly a great indicator of our *consistency*. I know that consistency doesn't necessarily imply *accuracy*. For that you'd have to look at the postfit residuals of the observations. I recall that we can fit the observed Earth-Mars distance to a meter or so, over a period spanning 40+ years, and to do this we need to account for perturbations from several hundred individual asteroids as well as the rest of the planets. Yes, our range measurements are that good -- a few meters out of tens of millions of km in the inner solar system, or 1 part in 10^10. -- Bill |

For the natural days are truly unequal, though they are commonly considered as equal and used for a measure of time; astronomers correct this inequality..." Newton In Newton's era they hadn't a clue what caused the natural noon cycles to vary and the later analemma with its wandering Sun is so perverse that it no longer requires mentioning.The equation of time reflects the rate of change in the orbital orientation of the Earth to the central Sun assuming daily rotation is constant,academics who work off a single axis for the Earth's daily and orbital motions may not care but it is a 100% observational certainty that the observed variations arise from two rotations to the central Sun.As daily rotation is constant and a separate motion,I repeat,a separate motion,the equalization of the natural noon cycle to an average is really a smoothing out of the orbital component for each noon cycle.This is why rotation never strays away from natural noon and why there are both 1461 natural noon cycles across 4 orbital circuits just as there are a corresponding 24 hour cycles for the same period.Academics may not care or do not have the ability to work through the technical details but effectively ,with graphics and imaging,there is nothing that can't be worked out to the satisfaction of all genuine astronomers. I won't put you on the spot and ask you what reference do you use to demonstrate that the Earth speeds up and slows down at different points in its orbit,you are too much of a decent man for me to do that,however,the vibrant topics have yet to surface from behind the mechanical astronomy of late 17th century empiricism which relied too much on clocks in drawing their conclusions on planetary dynamics. |

"At the time of the dinosaurs, Earth completed one rotation in about 23 hours," says MacMillan, who is a member of the VLBI team at NASA Goddard. "In the year 1820, a rotation took exactly 24 hours, or 86,400 standard seconds. " NASA All you can do now is live with conceptual rot that the new crowd pay no attention to and neither do I apart from demonstrating that the stellar circumpolar error tries to circumvent the 24 hour system in tandem with the Lat/Long system and an equatorial speed of 1037.5 miles per hour.You cannot expect me to entertain a person who cannot equate one 24 hour cycle with one rotation of the Earth as it represents an indoctrination that is so severe it may actually surpass the unfortunate creationist ideology.A person who cannot reason out the most immediate experience of a gorgeous 24 hour day and all its effects arising from one rotation is already dead in their mind so awakening people to the stable astronomical narrative becomes the sole aim of what I do and where possible add new material which modern imaging allows. Sorry about your intellectual impotence and your inability to see that things have changed and not for the better with the new spiel of the Earth slowing down with assigning special significance to the year 1820.The opportunity is not to contend with the new mess but revisit how the timekeeping systems were put together by brilliant people over many thousands of years,people who knew what they were doing. Again,if you are so certain that the Earth turns in 23 hours 56 minutes 04 seconds then your issues are not with me but your own empirical community who simply change their story and cobble together whatever assertions they need to fit contemporary concerns..God help you - truly. |

You do not know the speed of light is relative to the source and not a universal constant as your tin god claimed. ALL your measurements are inaccurate. Your word is worthless, Compo, it impossible to predict where the Earth will be to a precision within its own diameter a year from now, and that is not even taking into a account the three-body problem which can only be solve numerically. Don't take my word for it, carry on believing what you cannot prove, based on a ridiculous assumption. -- This message is brought to you from the keyboard of Lord Androcles, Zeroth Earl of Medway.

But that's the part he _doesn't_ know, because he is wilfully ignorant of such matters, claiming that this stuff all comes from nasty old Newton's empirical agenda. John Savard |
