The first observation of the #JovianMoons was on #ThisDayInHistory in 1610. #GalileoGalilei used his custom telescope and first saw the larger #Ganymede & #Callisto, with the smaller #Io & #Europa sighted the following night. These observations proved the #Copernican solar model.

I think the 'embarrassing part' being there the whole time is the most interesting - far more than any of the myriad trivial puzzle-solving bits added to the pile over the past several decades.

Not enough serious thought seems to be going into the idea that the odds seem highest that both theories are wrong in key areas. As you highlighted, there aren't that many fundamentals that affect both, & we should be focusing more on the relations of #time & #scaling, which operate quite differently between our principal abstract dimensions.

There's also a very good chance, imo, that the embarrassing part extends well beyond these 'pillars' of scientific models & thought. Both of them pointed clearly to the fact that 'classical' (previously just known as 'right') #physics concepts were not as we had pegged them, yet who among the noted scholars went backwards from there, as a detective would in order to solve a crime?

Instead, in proper pre-#Copernican fashion, they just set about adding layers of arbitrary #complexity in order to leave the past as-is, and race toward the next paper on some low-hanging fruit that supported the '#quantum revolution' that was now their defacto career title track.

No one has looked back since, I'm afraid.

📆 1950 the question "Where is everybody ?" occurred to #Fermi at lunch 🍽️ one day.

• The #MilkyWay 🌌 contains hundreds of billions of stars 🎇, and billions of them are similar to the #sun ☀️.
• It is highly likely that some of these stars will have planets 🪐 that are similar to #Earth 🌏.
• If we assume – via the #Copernican principle – that Earth is not particularly special, then #intelligent life should also exist on some fraction of these Earth-like #planets.
• Some of these intelligent life-forms might develop advanced technology, and even #InterstellarTravel.
#Interstellar travel would take a long time, but as there are many sun-like #stars that are billions of years older, there has been plenty of time ⌛ for such #travel to have occurred.
• Given all this, why haven’t we met or seen 🔭 any trace of #aliens 👽 ?

What is the Fermi Paradox?

The Fermi Paradox – named after the Italian-American physicist Enrico Fermi – can be summed up in a simple question: Where is everybody?

The Religious Significance of Kant's Copernican Revolution

#19febbraio 1473, nasce l'astronomo polacco Niccolò Copernico. Noto per aver promosso l'evidenza del sistema eliocentrico contro il sistema geocentrico fino ad allora sostenuto in Europa.
