Kan du nu bara förklara en liten sak för mig:
Varför stämmer inte planetpositionerna i Tychosium med verkligheten?
Tack på förhand!
Då ska vi se. Häromdagen gjorde jag en liten koll på följande vis. Jag bad en AI om en lista med stora astronomiska händelser från 1600-talet och framåt som involverade planeter i solsystemet där det finns väl dokumenterade faktiska observationer av dessa. Därefter jämförde jag Stellarium och Tychosium med dessa. Se lista nedan. Så jag tycker professorn ska kontakta Stellarium och NASA och ställa samma fråga. "Varför stämmer inte Stellarium/JPL med verkligheten?" Och sen oavsett vad de svarar, bara upprepa din fråga.
Och sen tycker jag det är viktigt att klargöra vad det är vi jämför här. Dvs en matematisk modell som lanserades av Copernicus och sedan justerades av Kepler och därefter av Newton och sedan av Einstein. Men det har inte räckt, utan för att få denna modell att fungera någorlunda så har man dessutom fått lägga in tiotusentals justeringar.
Och i andra änden har vi Tychos/Tychosium som gör samma sak med en handfull cirklar som roterar i konstant hastighet. Datan och beräkningarna skulle rymmas i en miniräknare. Så som jag säger ibland, även om man kan inte kan acceptera att det här är den korrekta konfigurationen av solsystemet (vilket detta naturligtvis visar tillsammans med all annan bevisning) så måste man i alla fall erkänna att vi funnit ett radikalt mycket enklare sätt att räkna ut planetära positioner.
Trevlig helg!

Discovery of Jupiter’s Galilean Moons (1610)
Event Description: Galileo Galilei observed Jupiter’s four largest moons (Io, Europa, Ganymede, Callisto) using a telescope, marking the first telescopic observation of satellites orbiting another planet. These observations, starting January 7, 1610, confirmed the moons’ motions around Jupiter, supporting the heliocentric model.
Observation Details: Galileo’s observations were made from Padua, Italy. The moons’ positions relative to Jupiter were recorded over multiple nights, with their RA and Dec changing due to their orbits.
RA and Dec (J2000.0, approximate for Jupiter on January 7, 1610): RA 04h 50m 00s, Dec +22° 00′ 00″ (Jupiter’s position; moons’ coordinates vary slightly due to orbital motion).

Transit of Venus (1639)
Event Description: The first recorded observation of a Venus transit across the Sun’s disk, observed by Jeremiah Horrocks and William Crabtree on December 4, 1639. This event helped refine the scale of the Solar System.
Observation Details: Horrocks observed from Hoole, England, and calculated Venus’s position on the Sun. RA and Dec were derived relative to the Sun’s position.
RA and Dec (1639 epoch, approximate for Venus during transit): RA 16h 10m 00s, Dec -20° 30′ 00″ (aligned with the Sun’s position at the time).

Discovery of Saturn’s Moon Titan (1655)
Event Description: Christiaan Huygens discovered Titan, Saturn’s largest moon, on March 25, 1655, using a refracting telescope. This was the first discovery of a moon around Saturn.
Observation Details: Observed from The Hague, Netherlands. Titan’s position was noted relative to Saturn, with RA and Dec recorded based on Saturn’s coordinates.
RA and Dec (J2000.0, approximate for Saturn on March 25, 1655): RA 12h 25m 00s, Dec -00° 50′ 00″ (Titan’s position varies due to its orbit).

Discovery of Uranus (1781)
Event Description: William Herschel discovered Uranus on March 13, 1781, initially mistaking it for a comet. This was the first planet discovered with a telescope, expanding the known Solar System.
Observation Details: Observed from Bath, England, with Uranus’s position recorded in Gemini. Its slow motion allowed precise RA and Dec measurements.
RA and Dec (J2000.0, for March 13, 1781): RA 07h 10m 00s, Dec +22° 40′ 00″.
