NEW EQUATION (BASED ON THE QUADRATIC) YIELDING 10 * 1574.4 (Update from the Migrator Model 2025 Jan 7)

This equation was derived following the logic of the quadratic correlation (of Boyajian's 48.4-day dip spacing with Sacco's 1574.4-day orbit periodicity). Though inspired in part by Solorzano's base 10 non-spurious finding (posted on this sub), it demonstrates a long-standing proposition of the Migrator Model that the 928-day periodicity proposed by Kiefer et al. is a structural pointer to the consistency of the asteroid mining template (sector division) - which points to a hybrid decimal-hexadecimal structure underpinning the data:

S = 1574.4

K = 928

T = 52 or S/16 - K/20

C = A - B

C = 870 in terrestrial days, but derived from the logic of the template (A = distance between D1520 and TESS 2019: 2378 terrestrial days) - B = the 52 regular sectors: 1508 terrestrial days). The logic of the template should be identifiable in the data to most intelligent species, so though the numbers may change with a hypothetical non-terrestrial calendar, the equation is true.

Standard Asteroid Mining Template = 1508 days from 52 regular (29-day) sectors, + 66 days from 2 extended (33-day) sectors = 1574.

Completed Template (re: the Fulcrum Cross Method) places the fraction on the fulcrum that bisects the template and from which the datelines of the sector boundaries are calculated within a given orbit (1574.4)

So how bout them lasers?

A laser was detected at KIC8462852 in 2019. But we haven't detected any follow ups.

But knowing astronomers they probably looked at it for 12 hours and decided that it never repeats. Lol.

Very interesting addition to the already fantastic coverage of possible ETI candidates from John Michael Godier, and a little detour into how KIC8462852 relates to this data. This guy is a class act in how to approach the possibilities with an open mind but without making a circus out of it.

GEOMETRIC FEATURES OF SACCO'S ORBIT AND PI (2023 Oct 18)

Here's the latest Migrator Model finding, elementary in simplicity but striking and consistent with the proposition that Sacco's orbit and Boyajian's dip spacing are a signal centred on π. It will be fascinating to see what the JWST data (after processing) will reveal, I suspect it will point to more than one circumstellar ring († see Caveats and Clarifications) and interestingly in the early days I did offer the speculation of bisecting planetary rings on this sub before developing the asteroid mining hypothesis. It would be extremely unlikely the (proposed) ETI would allocate all their asteroid processing platforms just to signal Sol, so additional infrared rings (even without line of sight) caused by their dust jets might have been detected.

Below is the extract from the academic download, then the link. It's worth remembering that 24 multiples of Boyajian's '48.4' (1161.6) can be extracted from π with the ratio signature method.

Extracts -

The proposed ‘3014.4 Signal’ is constructed from the ‘96 Master Key’ as 9.6, and π as 314. Two multiples of Sacco’s orbit (1574.4 * 2 = 3148.8) and two multiples of the ‘abstract circle’ (1440 * 2 = 2880) manifest when adding and subtracting of the ‘abstract ellipse’: 134.4. This +/- route in 3014.4 pointed the way for us to find the quadratic correlation between Sacco’s orbit and Boyajian’s 48.4-day dip spacing. On the supposition the Migrator Model hypothesis is correct, the ETI uses π not as an equational ratio, but in discrete hundredfold stages applying the ratio signature method, which can be defined as multiplying a number by 100 (and 100 multiples thereof going forward) and subtracting non-integers (‘n’):

π x 100 - n = 314

π x 10,000 - n = 31415

A remarkable structural feature of π rendered with this method is the use of the abstract circle in the first two stages, using 0.625 (re: the Nomenclature in the links) and half the number, 0.3125:

31415 / 0.626 = 50264

50264 / 0.3125 = 160844.8

160844.8 - 144000 = 16844.8

16844.8 - 14400 = 2444.8

2444.8 - 1440 = 1004.8

1004.8 * 0.3125 = 314

The method, which points to a deeper logic within the ratio signature method as 31415 in converted back into 314, uses multiples of 1440 but appears to work only at the first two stages (i.e.: 314, 31415). Further analysis may yield other geometric numbers that produce the same effect applying the method deeper into π (3141592, 314159265 etc).

PI, THE CIRCLE AND 484

The 928-days orbit periodicity proposed by Kiefer et al. is a foundation of the Migrator Model (as covered exhaustively). Though the model is not built around the number for the orbit (it is built around Sacco’s 1574.4 days), the number (928) comprises 32 standard sectors and not only do the twin signature transits fall precisely on the sector 8 and 40 boundaries, but the duration of the dips approximates to 4.44 days:

928 - 444 = 484

Ten multiples of Boyajian’s 48.4-day dip spacing. So looking in reverse so to speak:

1574.4 - 928 = 646.4 ††

646.4 + 484 = 1130.4

1130.4 = (3.14 * 360)

444 in the Migrator Model has been termed the ‘lockdown’ number, a number to flag the structural features of the orbit as a signal:

1130.4 + 444 = 1574.4

Note most of the numbers in this finding are not ‘abstract’ but astrophysical (Sacco’s 1574.4; Boyajian’s 48.4 as tenfold; and Kiefer’s 928, and indeed 4.44 as one hundredth), and further 646.4 is simply the difference between 1574.4 and 928. Pi is a constant, and 360 arguably a universally logical circle division.

† Caveats and Clarifications

I genuinely have no idea what the JWST detected nor what will be presented, the idea there may have been evidence for more than one circumstellar ring detected in the infrared is speculation on my part. I wish to make it absolutely clear to visitors to this sub that though the Migrator Model uses the work of Boyajian (et al.), Kiefer (et al.) Sacco (et al.) and indeed Bruce Gary too, this in no way implies their endorsement of the hypothesis on any level. Finally, wish to clarify once more that the Migrator Model is not an extraordinary claim (X is true because of the data), but an extraordinary proposition (X is consistent with data). This is to say, it may have a probability of being correct, therefore an inverse probability of being incorrect.

†† More importantly for this structural fragment 646.4:

S - K = J

4 J - 48B = S/6

K = Kiefer's 928. S = Sacco's 1574.4. B = Boyajian's 48.4. J = 646.4 (from S - K)

Program Status: Program has been Completed

So, if I'm not mistaken, JWST has already looked at our star for about 6 hours: https://www.stsci.edu/jwst/science-execution/program-information?id=2757. Where can one follow the results? Are these observations open public data, or are there restrictions? Could some of you maybe provide an (unofficial) update?

Alien Megastructure may not be alone?

Alien Megastructure may not be alone?
I’m driven to wonder if the dust referred to in the article might be nano assemblers that have glitched and are endlessly building habitat and running into resource shortages then beginning to look for new resources.   The idea that what ever it is causing the dust to seem  to be spreading fits the conjecture. If the nano has the ability to cross a solar system then it has the ability to reach near by stars. It also seems to me that the lack of IR from the dust may be because of efficiencies in nano-bot manufacture that we have not discovered. I read once that unregulated self assembly would lead to destructive levels of waste heat.

A type II Kardashev civilization, or a civilization striving for the benefit of that level of technology might make a disastrous mistake inadvertently creating grey goo (runaway self assemblers).

MATH BEHIND THE QUADRATIC CORRELATION (Migrator Model 2023 May 10)

I've been asked to share the math for the quadratic correlation between Boyajian's 48.4-day spacing and Sacco's 1574.4 day orbit. So in the interests of science, here's what my physicist (masters in theoretical physics and advanced mathematics) did with what he termed 'my half orbit thing' - the '492 structure feature or signal.'. Note 'S' in the top working is initially 1574.4 (to derive 3.2 as in the 492 signal), but the 'S / 2' that ensues is 1573 / 2 (Sacco's 65 x 24.2 = 1573).

B = 48.4

S = Sacco's orbit (as 1574.4 - also as 1573 in part of the workout)

T = 52

BEST FIT EQUATION FOR SACCO'S ORBIT AND BOYAJIAN'S 48.4-DAY SPACING (Update 2023

It shows strong consistency with the key numbers of the template numbers 16 and 52.

S = Orbit, B = Boyajian spacing (48.4), T = 52 (derived not just from the 52 sectors of Template-B, but also crucially from 0.625 (32..5 / 52). Follow the equation and you get 1574.3776 (rounded up at the fourth decimal place).

T might best be defined as the nearest fit of the dip spacing within the orbit (1573 in our calendar) divided by 30.25 (52 for us).

THE SKARA-ANGKOR PLATFORMS INSIDE THE ORBIT PERIODICITY (Update 2023 April 12)

This is a fundamental breakthrough for the Migrator Model because key numbers of the proposed Skara-Angkor Signifier (3016 and 3132) can be found inside Sacco's 1574.4-orbit periodicity itself. The model's template divides 1574 (note sans fraction) into 52 standard (29-day) sectors and two extended (33-day) sectors: 54 total sectors. The Skara-Angkor Signifier is constructed from where Skara Brae, or Angkor, sit within their respective abstract extended sectors, each 16 days from the line (the fulcrum) that bisects the orbit. To understand the significance of this finding, note there is no necessary connection between the extended sectors (let alone the Skara-Angkor Signifier) and Sacco's orbit.

Where 'n' = non-integers:

16 / 33 (extended sector) = 0.48 r. (x 100 - n = ratio signature 48)

13 (days to complete a standard sector) / 33 = 0.39 r. (x 100 - n = ratio signature 39)

29 (days of standard sector) / 33 = 0.87 r. (x 100 - n = ratio signature 87)

48 x 39 x 87 = 162864 (Skara-Angkor Signifier)

162864 / 54 (total sectors) = 3016 (the 54-platform)

162864 / 52 (standard sectors) = 3132 (the 52-platform)

XXX

1574.4 / 54 = 29.15(5 r.)

29.15 r. / 29 (Elsie Key) = 1.00536398 (fraction to first eight decimal places)

1.005363985 x 30 (Elsie's sector ratio) = 30.16091954 (fraction to first eight decimal places)

30.16091954 x 100 - n = 3016 (54-platform)

XXX

1574.4 / 52 = 30.27692308 (fraction to first eight decimal places)

30.27692308 / 29 = 1.04403183 (fraction to first eight decimal places)

1.04403183 x 30 = 31.32095491 (fraction to first eight decimal places)

31.32095491 x 100 - n = 3132 (52 platform)

XXX

Because the methodology is consistent, particularly in relation to the Elsie Key Nine Step Method, this is robust connectivity between the model's proposed signalling structure and Sacco's orbit periodicity - crossing from the abstract to the astrophysical number 1574.4.

Could Space Dust Help Protect the Earth from Climate Change?

This is crazy. I'm not a scientist, just an interested observer. But what if...

"The paper, published today in the journal PLOS Climate, describes different properties of dust particles, quantities of dust and the orbits that would be best suited for shading Earth."

"In the second scenario [computer simulations], the authors shot lunar dust from a platform on the surface of the Moon towards the Sun. They found that the inherent properties of lunar dust were just right to effectively work as a sunshield. The simulations tested how lunar dust scattered along various courses until they found excellent trajectories aimed toward L1 that served as an effective sunshield."

Could this technique apply to the dimming around KIC8462852?

What does ChatGPT think?

explain the anomaly around "tabby's star"

"Tabby's Star," also known as KIC 8462852, is a star located in the constellation Cygnus that has exhibited unusual and unpredictable fluctuations in brightness. The anomaly was first discovered in 2015 by citizen scientists using the Kepler telescope. Several theories have been proposed to explain the anomaly, including the possibility of a cloud of comets passing in front of the star, or the existence of a massive alien structure such as a "Dyson sphere" built around the star. However, none of these theories have been conclusively proven, and the cause of the anomaly remains unknown.

write a news article from 5 years from now after we learn what the cause of the variation in "KIC 8462852" is

NASA scientists have finally uncovered the mystery behind the strange behavior of "Tabby's Star," also known as KIC 8462852. For years, the star located in the constellation Cygnus has puzzled scientists with its unusual and unpredictable fluctuations in brightness.

After five years of intense study, using multiple space telescopes and ground-based observatories, scientists have finally determined that the cause of the anomaly is a massive planet, roughly the size of Jupiter, orbiting the star at a close distance. The planet is located in a highly inclined orbit, which causes large variations in the amount of light blocked from the star as seen from Earth, resulting in the observed dips in brightness.

According to lead scientist Dr. Jane Smith, "This is an incredibly exciting discovery. We have been able to confirm the existence of a massive planet orbiting KIC 8462852, which has been causing the fluctuations in brightness observed for years. This is a major step forward in our understanding of planetary systems and their potential to support life."

The team also discovered that the planet has a thick atmosphere, potentially composed of water vapor, which increases the possibility of finding evidence of life on the planet.

The discovery of a massive planet orbiting KIC 8462852 has opened up a new realm of possibilities for future research and exploration. Scientists are now planning to study the planet in more detail to understand its atmosphere and potential habitability.

This groundbreaking discovery will be featured in an upcoming issue of the journal Nature and has been met with widespread excitement and interest among the scientific community.

KIC 8462852

Well this anomaly is in fact, just an alignment of planet with their kind large satellite. Us observing are in the axe where the planets orbiting that star all aligned gradually in those 4 years. We were lucky, who knows in how many years they will happen again in the right angle for us to see the starlight dime over 20%

Yes, not constant, diverging from original article on the star.

The error is gigantic though. radial_velocity_error 3.9062264 km.s**-1

Pretty indicative of a closer companion binary star.

Let me know what u think.

Years ago i vented the possibility of this being a binary system as per https://imgur.com/a/6335i

SACCO'S ORBIT INSIDE π (The Migrator Model Update 2022 March 5)

Update 2022 July 5 - the 1536 Signal -

https://drive.google.com/file/d/1u3xlhFDEPXI5BYhEV6Ib4fTBNuLmT6gM/view?usp=sharing

XXXXX

This post will be my last on the KIC sub for some time (so for those of you averse to the Migrator Model you can heave a sigh of relief) -unless I stumble upon something as big as the proposed π signal (unlikely). The next stage for the Migrator Model depends on various outcomes and if there's a breakthrough on a scientific level. For now though, adieu and it has been an exciting ride; but there's not much more I can contribute to the debate than this...

The following finding points to an artificial orbit constructed to be intelligible applying our planet's 24-hour spin (that is, in whole calendar days). This would be at the far end (the tertiary level) of the signalling strand of the Migrator Model (caveat), but the findings are remarkably self-consistent. An ETI visit past our planet 3000 years ago, the pyramids would be up. Sending a signal back to Tabby's Star to instruct the construction of an artificial orbit, the signal would reach us about now. This is one 'imponderable' but not beyond the limits of science.

The construction of π as a ratio signature (314) is covered in the Academic Downloads. The Elsie Dip Signifier 1566 is a foundational number in the proposition of the signifiers as it gives the Elsie Key Nine Step Method (see the Nomenclature Academic Download on the Migrator Model sub). 1566 is too large a number to subtract from π (314), so divide by 10...

1566 (Elsie dip signifier constructed out of ratio signatures) over 10 = 156.6

314 (π as ratio signature) - 156.6 = 157.4

1/10th of the Elsie dip signifier through this method yields 1/10th of Sacco's orbit (sans fraction). If commenting on this post, please be civil (thank you). So, taking the Elsie dip signifier here as a pointer to apply the Elsie Key and Elsie's sector ratio used in the the Elsie Key Nine Step Method...

314 - 156.6 = 157.4

157.4 - 29 (Elsie Key) = 128.4

128.4 - 30 (Elsie’s sector ratio) = 98.4 (1/16th of the full orbit with fraction)...

16 x 98.4 = 1574.4

Note that Elsie in the template encompass a span of 98 days (1/16th of the orbit) with respect to the fulcrum from which all the sector boundaries are calculated and is analogous to the diameter in π. Another route to 1/8th of the full orbit periodicity...

314 over - 65 (Sacco's Multiplier to Boyajian's 24.2-day spacing) = 249

249 - 52.2 (sector ratio key) = 196.8 (1/8th orbit)...

196.8 x 8 = 1574.4

XXX

This method is also an affirmation of the proposition of the ratio signatures...

65 x 52.2 = 3393

3393 over 87 (ratio signature of a standard sector) = 39

39 = the ratio signature of the 13 days Skara and Angkor requite to complete a standard sector in the extended...

87 - 39 = 48 (= ratio signatures of Skara Brae and Angkor)...

39 x 48 x 87 = 162864 (the Skara-Angkor Signifier) *

162864 over 58 (Skara-Angkor Key) = 2808

2808 = 52 x 54

XXXXX

*

29 (days of one of the 52 standard sectors) over 33 (one of the 2 extended sectors) = 0.878787 recurring

0.87 r x 100 (discard remainder) = ratio signature 87

16 (days of Skara Brae / Angkor each side of the fulcrum as the diameter in π) over 33 = 0.484848 recurring

0.48 r x 100 (discard remainder) = ratio signature 48

13 (days Skara / Angkor require to complete a standard sector in the extended) over 33 = 0.393939 recurring

0.39 r x 100 (discard remainder) = ratio signature 39

π (first 100) 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679 †

x100 (discard remainder) = ratio signature 314

Note also 65 multiples of the fraction in 24.2-day spacing = 13 days.

Logic of 492 Signal in π

https://www.reddit.com/r/MigratorModel/comments/tkw1xs/logic_behind_the_492_signal_in_π_update_2022/?utm_source=share&utm_medium=web2x&context=3

For a bit of (dated) fun, check out this Star Trek episode from the original (second) series: Wolf in the Fold, where Spock drives out a hostile alien intelligence infesting the Enterprise's computer banks by instructing the computer to calculate π to the last digit. As a transcendental number without resolution, turning π into a ratio signature is eminently logical. Putting the jokes aside, the Migrator Model (if correct) has immense implications for our species.

Any way to tell if there is a correlation between distance and size of dip with the Boyajian's star analogues?

I've been thinking about this paper https://iopscience.iop.org/article/10.3847/1538-3881/ac3416/pdf, which discusses analogues of KIC8462852. In regard to them being SETI candidates, is there any way to tell whether there is a correlation between the size of the dip and the distance they are from some hypothetical origin point?

My hypothesis is that, if the unusual dips were technosignatures, stars that were colonised first would potentially have larger dips and ones that were colonised later would have smaller dips. Unfortunately I am neither literally nor figuratively a rocket scientist, so I have no way of checking my theory. Does anyone here have any thoughts on this, or know how to crunch the numbers?

I searched for 3 stars from the new article looking for analogs of KIC 8462852. And none of them came up in simbad, where can we get more information about these stars?

On a side note, only 1/200 stars have a visible transit. We have not found about 40 stars similar to KIC 8462852. Does that mean there are 8,000 more KIC 8462852s out there that we haven't seen yet in our neighborhood? I kinda like those odds.

Event Horizon YouTube channel has an interesting new interview

A great new interview over at Event Horizon, referencing KIC8462852. The interview is with the discoverer (Edward G Schmidt) of the "clustering" (in location as well as stellar type) seen in stars that appear to dim in a similar way to KIC8462852.
