Heliocentrism and Geocentrism

A simple animation at which is easily to observe how different and difficult is to describe a planetary motion according to Geocentric point of view, in relation to a Heliocentrism.

I remember reading that the ancient Greeks couldn't make sense of the movement of the planets until they considered a heliocentric model

[DukeEastway]

Great animation. Shows why the geocentric concept became too complex as more planets were discovered.

[prasoonjha]

Claudius Ptolemy was a real crazy genius to create such a complicated model for an idea we now know to be untrue. Probably many difficult topics of today will be replaced by much simpler ones in the future too.

I wonder if we have an animation for Lunacentrism.

I love how under geocentrism, Jupiter just chills in the same spot for a little bit in it's orbit, like it's taking a breather ☠️

[kottonmouthhero]

Geocentrism still makes sense if you consider the planets are following the torus field. It's actually kinda beautiful

[jonathanaarhus]

Fun fact: the ancient greeks were basically doing Fourier series without realizing it. Any arbitrary orbit can be modeled with the right epicycles.

The pattern with the geocentric model actually looks cool btw

Geocentrism: the solar system but on drugs

[mr.markofski]

Bro, the idea heliocentrism must’ve been one of the greatest plot twists in history

Imagine the first guy to ever suggest the idea

[ПолорЄлеон]

Gees, it's been hundreds of years, there was no need to diss it that hard

We still use both models in astronomy. The Earth observational Ptolemy model tells us where Jupiter, the Sun, Mars, etc will be any given observational moment.

Both models are correct from different chosen centers. Our sun is not the center of our universe either....but it is from our observations. Nothing is the center of anything as what we observed isn't where it was where we now observe it.

With hand calculations the heleocentric model of Copurnicus was much easier for Kepler to plot for his planetary movement laws. Physics is often about picking the best mathematical point and relating vectors and curved formulas to it.

Kepler found that the planets orbit in an ellipse, so the sun is not the center either...but one of two foci....a center point is between the sun and that other foci...in empty space.

[Morec]

If I didn't know I was the center of everything already, I'd be pretty convinced by the heliocentric one.

[Nora-kybt]

Oh my goodness, the geocentric model is so beautiful! Definitely the way God would have designed it 🙏👍😃

[jerotoro]

I mean, looking at the geocentric model you can see how each planet is the same distance from the sun at all times. They all move relative to the sun's position, is almost like they revolve around the sun WAIT

[Tletna]

However, both models are correct in a way. For example: the Sun and the Earth both revolve around one another but we say the Earth orbits the Sun because the Sun is far more massive and play a much bigger role in that interaction than Earth does. And, as this video shows, it makes predicting orbits of other objects in the solar system much easier (though not as simple as this video makes it seem).

[jmixes]

(I am not a geocentrist)

But fun fact: the reason culture was uneasy to switch to heliocentricity was not because 'they thought they were the center of the universe' (I mean, literally they did, but not in a prideful way) in fact, quite the opposite. They believed anything higher than the moon to be divine/eternal, and thus placing the earth as 'just another planet' basically defiled that divinity.

[martinb.]

Imagine someone from ancient times trying to remember how the planets 'n stuff orbit
"...so this one goes woop, and then woop, this is only wee, the other's weee woop weee and the other goes woawoawoawoa..."

[michaelkhoo]

Nice animation, I will use it in class, thank you!!!

[racionador]

Geocentrism fails in the momment we found out other planets had their own moons.
the entire idea on Geocentrism is that earth is the literal center of the universe and everything that mattered happened here or was related to earth.
