@UCcO6SOkIyjgM8CEfm2-5Aow well, Aristarchus did not prove it as far as I know, and this is one reason the Aristotelean model kept being used until the XVI century. It's easy to prove Earth is a sphere, but heliocentrism is quite hard to prove actually. The apparent lack of stellar parallax (which can only be measured with very precise instruments that did not exist until the XIX century) was used as an argument for a few decades after Galileu and Kepler. Galileu's proofs were quite faulty in themselves. The best about Galileu was that showing the Jovian moons was definite proof that NOT EVERYTHING orbited the Earth.

@Huckleberry00 Copernicus' model didn't have any simple circles, you might want to actually look at the model rather than the "diagram of the spheres" (the rough locations of the orbits) that's often incorrectly shown as the model. Copernicus' moon has a _double_ epicycle. No evidence survives as to the nature of Aristarchus' claims, and it's as likely he was making a philosophical argument like the Pythagoreans (who argued the universe had a "central fire" due to different opinions on the hierarchy of elements, but did not think it was the sun) as that it had any material basis.

@@Huckleberry00 We have no idea what the basis of Aristarchus' claims were since the only surviving information on them is a very skeptical evaluation of his claim by Archimedes. It could just as easily have been a philosophical claim based on a different opinion of the hierarchy of elements: we already know that was the justification for the Pythagoreans, who believed fire to be greater than Earth and believed a great fire was at the centre of the universe, but didn't think it was the sun. Also, Copernicus' circles are far from simple, they're actually more complex than the Ptolemaic model when the epicycles are included. Kepler wasn't working with Copernicus at all, he was working with his mentor Tycho Brahe's geo-heliocentric model (the sun orbits the Earth and all other bodies orbit the sun), but couldn't match this up to Brahe's data for the orbit of Mars. He eventually found that the data could only be explained if the Earth and Mars were both in elliptical orbits around the sun.

Considering she was 60 at the time, probably not much... Also film has some wild historical inaccuracies... She was a neo platonist philosopher not the atheist expert in astronomy and mathematics, she did not prove heliocentrism nor the elliptical orbits and most of the inventions credited to her were invented well before the 4th century

Let's not forget Anaxagoras,the philosopher who left his town in Asia minor,under Persian occupation,to go to Athens and teach philosophy.He's been teaching to the future teachers of great philosophes like Socrates,teacher of Platon,one the greatest of all time.When he told them that the Sun is an asteroid full of gas and heat that sends light all-over the world along with energy,they asked him either to exile or die.He offended the Gods,since they had The Sun as their God.The poor fellow had to leave away from Athens where he spent 2/3of his live and go and die somewhere else.Oligarchy is fascism, meaning that do as we say, don't do as you please.

Hypatia questioning the Ptolemaic model, let alone figuring out a Kepleresque heliocentric is so absurdly stupid it’s painful. It’s such an annoying trope in movies when writers attempt to project modern knowledge on intellectuals of the past. Hypatia especially was a Neoplatonist. She organized and commented on the Almagest as we know it today. Not only did she believe the geocentric model, she knew the science behind it more than just about anyone alive at the time.

This movie is historically accurate as Braveheart and The Patriot combined. There actually was riots in Alexandria at the time but there were atrocities on all sides during the riots and Pagans, Christians and Jews attacked each other but mass stonings never occurred. It's especially nonsensical how they showed Hypatia proved the elliptical movement of the planets millennia before Kepler, while drawing circles in the sand with a stick... Without any mathematics.., Kepler only needed a lifetime of astronomical observation and lifetime of calculations plus all of the data collected by Tycho Brahe during his lifetime. The fact that much of the knowledge from the library was lost is also fault of the scholars themselves because the common folk never saw any gain from it. That supposed steem engine they invented was useless because the inventor never found any actual use for it, and like most of their other "inventions" was used for entertainment of the rich. Also, and papyrus isn't especially durable material, it tends to fall apart quite easily...look at the dead sea scrolls for example and they were kept in perfect conditions avoid of humidity. Some people treat the plot of historical films that fit their agenda as a fact, which is a mistake. The actual library of Alexandria was burned in the roman civil war around 48 BC, where according to Plutarch Ptolemy's forces besieged the city with Julius Caesar inside after which the Roman soldiers ended up burning their own ships as a disguise so the fire spreaded around the city burning large portions of the library. It's unclear how many of the scrolles survived but there probably was a portion left according to writings from various scholars. Between 270 and 275 AD, the city of Alexandria found itself at the centre of a rebellion against the Romans and a target of an imperial counterattack in which Emperor Aurelian ordered the entire quarter of the city where the library was located to be burned to the ground so that probably destroyed whatever remained of the Library, if it still existed at that time because there is reports of several fires and earthquakes before that. According to some historical sources the Serapeum was demolished by the order of the Christian bishop in 391 AD but none of the historcal sources from that time period mentions that it housed books. So it is unknown did it housed any books at that time period and quite possibly served merely as a gathering place. Hypatia's death in 415 AD when she was in her 60s was unconnected with the burning of any part of the library and her assassination was done because of political reasons. Oh yeah, and after the schollars of Alexandria copied any book they would usually destroy the original, so the question is how much ancient knowledge we haven lost because of that.
