It’s really big, but its vast orbit won’t bring it past Earth.

June 23, 2021: Astronomers have just discovered a comet so big, it might actually be a minor planet. The object is named 2014 UN271. Astronomers Pedro Bernardinelli and Gary Bernstein found it in archival images from the Dark Energy Survey. It appears to be about 100 km wide, 2 or 3 times bigger than record-breaking Comet Hale-Bopp of the 1990s.

Now for the bad news. Although 2014 UN271 is falling toward the sun, we may never see it with our naked eyes. At closest approach in early 2031, the behemoth comet will be just outside the orbit of Saturn, too far for naked-eye viewing. Some astronomers are estimating a maximum brightness near magnitude +17, about the same as Pluto’s moon Charon.

It’s still an amazing discovery. 2014 UN271 has an extremely elongated orbit stretching from ~the neighborhood of…

    Oh goody. Spiral arm trash coming this way, sorta. Now for some Van Winkle zzz’s.

    “Now for the bad news. —” Why??

    It -its coming- might be ‘bad news’. We are at an Eddy cycle peak. Good times, but when things begin to turn sour. A tip from another blog site led to this info; about an earlier Eddy peak at 1750bce. The 3.7kyr Kikkar event; link https://vnexplorer.net/tag/3-7kyrbp-kikkar-event

    Just what the doctor ordered to cure Covid; and other medical and moral issues.

    Not exactly accurate, but if you assume (like experts who continually appear as “surprised” characters in “science” stories) a 980 jigsaw piece peaks around 2100 or shortly thereafter you can imagine 122.5 years of “the same” (maybe assuming expertise isn’t again a source of “surprise”).

    I suggest refocusing on something deeply concerning: the next-level context subsuming 980 & 1470 jigsaw pieces.

    The 6000 and 7200 year lunisolar waves (even more so than the multidecadal-centennial solar waves) are actually alarming (FAR more so than any CO2 narrative). None of these are cycles in the traditional sense. They are modular forms and due next is a careful study of the forms (identification, sorting, and classification) of spatiotemporal symmetry. For an expert on modular spatiotemporal forms (specifically flow forms facilitating discrete material aliasing), it should be possible to measure an exact fit (all the way down to ENSO). (A simpler analogy: Farey deviation from uniform.)

    This is an area of mass misinterpretation, misunderstanding, and misrepresentation (obviously arouses suspicion that some powerful group has geophysical secrets to keep (maybe wise heard davo$ (symbolically if not literally)).

    The prerequisite trust for a more sensible and productive discourse remains absent (more so than ever). The 6000 year cycle is frightening and we’re going up the steep part. (No one says a word.)

    Certainly having riots in Washington is counterproductive and that is probably why some baited as they did to expose “allies” (actually enemies of exploration, truth, stability, and security).

    To do good it takes better-balanced leadership than divide-and-conquer-wizards will ever offer. Trump wasn’t able to help in the right way (even though disappointed folks hoped for better).

    May peace, tranquility, security (including financial), and everlasting equality (including financial) be with you no matter your nation, race, faith, “socioeconmic status”, etc.

    FYI I don’t vote and I don’t support any party or any wing of any party (hence the “myth or math” symbolism to record what it was actually like under covid tyranny in the ever $0 “generous” west).

    Exercises: 1. Count the peaks on Rial’s classic graph. List the deviations from 7200. Understand their structure. 2. Do not underestimate how frightening the 6000 year cycle is. Keep an open mind that IRD, 14C, & 10Be records are being misinterpreted. Conspiracy theorists: This information is NOT for you (no spies here trying to bait you into riots and prison). It’s for academics (who’ll ignore it no doubt).

    Peace

    PV, thanks for the tip (hoping I can decipher it).

    The link in the above pointed to an exact date, and to an abrupt event. Civilisation downturn at the same time elsewhere had been found. This was an additional location plus an anticipated possible source/reason/cause (which matches the subject of this thread). But was it?

    My interest is various or multi-fold. Possibly ‘Kikkar’ means depression (kikkara or kikkra (short diminutive) = cup -maltese). Civilisation was abruptly erased from that fertile location, but which was a depression full of bitumen pits. For centuries afterwards it did not support life. Next Eddy root is 1300bce, the point of total collapse in many places (Babylonian, Mycenaean,–).
