#heliocentric — Public Fediverse posts

#Aristarchus's #heliocentric model, proposed 18 centuries before #Copernicus, is a powerful reminder of how suppressed ideas resurface in the #history of science.

`Epicycles are often cited as one of the biggest problems with the Ptolemaic #geocentric model. And that is precisely what Copernicus is taking aim at here. That’s not to say that Copernicus was fundamentally against epicycles. Indeed, his own adherence to uniform circular motion forced him to include #epicycles in his model. But what #Copernicus is criticizing here is the size demanded by the Ptolemaic model for #Venus in particular.`

Poetically, Galileo was sentenced for heliocentric heresy the day after the summer solstice.

Can’t make this shit up.

In lofty circles I pull weight,
Enjoy the company of great
Philosophers and men of science,
And find a way to end reliance
On faulty models. Yet I cleave
To custom—I won’t take my leave
But hold on tight until I burst:
A compromise that’s still Earth-first.
