Ptolemaic Planetary model
Loading...
Uploaded by rufjunk on Jul 25, 2008
This model originated over 2000 years ago to account for the various 'wanderers' in the sky. These wanderers were of course the planets - our solar systems other local worlds. Hope u like the music too.

The reason an Earth centered model was accepted for so long was because there was no evidence (that could be measured with the tools of that era) that the Earth was moving.

@luismedina2008 this has nothing to do with any god.... This is philosophical science.

God Bless you.

one of the main reasons that people didn't question the earth center mobdle is that Aristotle says say and in those days whatever aristotle says is true.
-
Wow. Ptolemy really was a genius... he just so happened to be dead wrong
-
I'd like to see a REAL model of this. Any suggestions?

I think I've looked at this video 20 times already in a row. Dude, you've got a gift for production.

Explanation: As the Earth moves around the sun, and passes by other plants moving around the sun, but slower because they are farther away, the planets appear to move backward and then forwards again, because the Earth is moving faster than them. To explain this while preserving the Earth-centric solar system, the Greeks showed that this "apparent retrograde motion" could be explained if planets did not orbit in one circle around the Earth, but around a circle that orbited another circle, etc.

Look up Ptolemy. He was an ancient philosopher. Arguably the first to publicly question the idea of just accepting without looking for evidence and for that is a very celebrated philosopher. Even though his idea about a geocentric solar system was incorrect, Ptolemy did provide a suprising solid mathematical explanation for the pattern exhibited by planets that moved throughout the night sky. Later, other philosophers would show the sun, not the earth, was the centar of the solar system.
