Dear all, I know... it's been a while since I've published any new Tychos research - but rest assured that I've not been sleeping and have kept incessantly digging for further confirmations of the model's validity. This last finding of mine (concerning Ernest Esclangon's observations) may - hopefully - take your breath away (although in a totally harmless, non-lethal manner !).

ESCLANGON'S "DISSIMMETRY OF SPACE"
I never cease to marvel at the amazingly precise observations made by some of the best astronomers of yesteryear - as they tried to make sense of this enigmatic Solar System of ours. Their tireless dedication to the noble quest of unveiling the secrets of our cosmos has not been in vain - and I'm glad to have contributed to highlight the significance of their invaluable lifetime efforts.

Ernest Esclangon (17 March 1876 – 28 January 1954) was the director of the Strasbourg Observatory and the Paris Observatory before becoming the President of the Société astronomique de France. In 1935, he received the Prix Jules Janssen, the society's highest award. In France, he is acknowledged as one of the most rigorous astronomers of his time. On his French Wikipedia page we can read that "Esclangon was attached to the establishment of the Chart of the Sky; it improved the precision of measurements in the fields of astronomy: measurement of time, variation of longitudes, variation of gravity." In any event, Esclangon was certainly a major authority in astrometry - even though most people will never have heard of him. I came across his work while navigating the website dedicated to Maurice Allais (the man who effectively disproved Einstein's theory of relativity).
Here's an extract from the Maurice Allais foundation's website that describes Esclangon's most peculiar observational program carried out around the years 1927/1928:
To the layman, this may all sound like a dreadfully complex affair - and it certainly took me a while to wrap my head around what exactly Esclangon's observational program was all about. "An optical 'dissymmetry' of space"? Hmm... What could this possibly signify?"The observations of Ernest Esclangon
Between 25th February 1927 and 9th January 1928 Ernest Esclangon carried out, at the Strasbourg Observatory, a programme of optical observations following a very different procedure from that which had been almost exclusively used until then in interferometric observations. It was as follows:
a) a refracting telescope placed in the horizontal plane facing north-west, autocollimation is used to cause a horizontal thread located at the focus of the telescope to coincide with its image reflected on a mirror that is integrated with the telescope. The angular displacement required for this coincidence is denoted by c.
b) Turning the device to face north-east, the operation is repeated. The angular displacement required to obtain the coincidence this time is denoted by c'. The magnitude whose evolution has been monitored over time is (c-c').
These observations comprised 40 000 sightings carried out by day as well as by night and divided into 150 series. The published reports included, in addition to a detailed description of the equipment used, the values for (c-c') for each series and the average temperature during each series as well as temperature evolution over each series.
By adopting the standpoint of sidereal time, Ernest Esclangon had detected a sidereal diurnal periodic component, whereas nothing in particular emerged when solar time was adopted.
He published his findings in a communication to the Académie des Sciences: “Sur la dissymétrie optique de l’espace et les lois de la réflexion” [On the optical dissymmetry of space and the laws of reflection] (December 27, 1927) in the April 1928 issue of the “Journal des Observateurs”, in which he also provided the experimental data collected: “Sur l’existence d’une dissymétrie optique de l’espace” [On the existence of dissymmetry of space]. In making use of these data, Maurice Allais established the presence, in addition to the sidereal diurnal component, of at least one long periodic component (estimated on the basis of a rapid analysis to be half-yearly)."

Well, please stay with me as I shall now illustrate the ostensible cause of this dissimmetry that Esclangon (unwittingly) observed. As you will see, it all amounts to yet another confirmation of one of the major tenets of the Tychos model, i.e. Earth’s proposed orbital speed of 1.6 km/h around its PVP orbit.
Here is the conclusive paragraph of Esclangon's paper describing his observational program of Earth's daily motions:

In short, here's what Esclangon's extremely rigorous series of telescopic observations (in Strasbourg) established :
- Between 3AM and 3PM (i.e. a 12-hour interval), the star quadrants at either side of Earth appear to be "offset" by -0.036" and +0.036" (for a total of 0.072").
- Between 9AM and 9PM (i.e. a 12-hour interval), the star quadrants at either side (i.e. looking East and West) of Earth show NO such dissimmetry in relation to the meridian.
Esclangon's concluding thoughts: "What is the origin of this dissimmetry? Does it come from the absolute movement of our star system? Categorical explanations would be premature. The question for now belongs to the experimental domain."
Before proceeding, I must remind the readers of the following key figures established by my Tychos research over the years:
- Earth moves at 1.6km/h around its PVP orbit (completing one orbit every 25344 years) and thus covers 14036km every year.
- This yearly motion of Earth causes the stars (located perpendicularly to Earth's motion) to appear to 'drift sideways '- or to 'precess' - by 51.136 arcseconds annually.
- In 12 hours, Earth will therefore move by approximately: 1.6km/h X 12h = 19.2 km (or 0.1368% of 14036km)
We see that 19.2 km (the distance covered by Earth in 12 hours) is 0.1368% of 14036km (the annual distance covered by Earth). Now, Esclangon's observed "dissimmetry" amounted to 0.072 arcseconds - yet, in a subsequent paper* he published in 1928, he appears to have slightly redacted this figure to about 0.07 arcseconds.
*Ernest Esclangon - " Sur l'existence d'une dissymétrie optique de l'espace" (1928): http://adsabs.harvard.edu/full/1928JO.....11...49E
And in fact, 0.07" amounts to - lo and behold - 0.1368% of 51.136", i.e. the annual stellar precession as of the Tychos model!
We may therefore conclude that the minuscule dissimmetry detected by Esclangon was caused by Earth's motion between 3AM and 3PM.
As illustrated in my below graphic, the 12-hour stellar parallax observed by Esclangon concerned the two star quadrants ("A" and "B") that lie perpendicularly to Earth's direction of motion. The other two star quadrants ("C" and "D") were not affected since we move at all times either away (from "C") or towards ("D") these two star quadrants. Hence, they will not exhibit any parallax between each other.

Et voilà. What Esclangon observed was, quite simply, a direct consequence Earth's ('clockwise') motion around its PVP orbit. Needless to say, Mr. Esclangon had - in his time - no manner of realizing the significance of his observed 'dissimmetry', nor much less to identify its causality. However, he should now be smiling in Heaven!
As a final note, I would like to point out that this (only apparent) "dissimmetry of space" observed by Esclangon is most probably what made Kepler postulate his bizarre elliptical orbits. This long-held inkling of mine was recently bolstered as I stumbled upon a fascinating paper by Laurence Hecht titled "Optical Theory in the 19th Century - and the Truth about Michelson-Morley-Miller". The entire paper is well worth the read - but the following sentence made me jump in my chair:
"The difference between the major and minor axis of the ellipse, which, as every school child is taught, constitutes the Earth's orbit around the Sun, is about one part in one thousand." https://21sci-tech.com/Subscriptions/Ar ... 998_Sp.pdf
One part in one thousand? Well, that's indeed most interesting (as viewed through the 'Tychos lens'): if Earth rotates around its axis at 1670km/h and moves across space at about 1.6km/h, this means that its orbital velocity is approximately 1/1000th of the value of its rotational velocity. In the interest of precision, let's perform a quick calculus using the more exact figures at our disposal:
1670km/h / 1.601169km/h (Earth's rotational speed / Earth's orbital motion) = 1042.98
40075km / 38.428km (Earth's circumference, a distance covered daily by a man at the equator / the orbital distance covered by a man every day)= 1042.85
One may thus easily fathom how this circumstance would have brought Kepler to assume that Earth's supposed orbit around the Sun is (very slightly) elliptical rather than circular.
