These theories have led us to what we now today (except for flat-earthers) even though the start to Astronomy was Astrology (Justifying things by saying it is true).]]> 2019-03-29 06:58:31 UTC https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346429446 alexaaaaaaamachdaslichtan https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346430203 The ancient greek philosopher believed that the spherical earth was in the center of the solar system proposing the geocentric model to explain how the sky works. This theory said that 55 crystalline concentric circles would travel around the earth at different velocities whilst carrying stars and planets]]> 2019-03-29 07:06:06 UTC https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346430203 alexaaaaaaamachdaslichtan https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346431057 2019-03-29 07:12:35 UTC https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346431057 alexaaaaaaamachdaslichtan https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346431136 2019-03-29 07:12:58 UTC https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346431136 alexaaaaaaamachdaslichtan https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346432860 The Ptolemaic model took Aristotle's idea for apparent motions of the planets. He assumed that each planet moved on an epicycle (a small sphere) which then moved on a deferent (larger sphere). The stars moved on a celestial sphere around the outside of the planetary spheres, which again was an assumption and not able to be proven. ]]> 2019-03-29 07:22:49 UTC https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346432860 alexaaaaaaamachdaslichtan https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346433467 2019-03-29 07:25:35 UTC https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346433467 alexaaaaaaamachdaslichtan https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346436829 Having been born five years after Nicolaus Copernicus published  “De revolutionibus“ which proposed the heliocentric model, Bruno "Philosopher of Astronomy" apart from continuing to try to persuade people of the heliocentric solar system also proposed theories of the multiplicity of worlds as well as the theory of an infinite universe. As his idea and Copernicus' idea were trying to disapprove the churches idea of the sky, the geocentric model, he was sentenced to 9 years in prison.]]> 2019-03-29 07:40:17 UTC https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346436829 alexaaaaaaamachdaslichtan https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346437169 This polish astronomer was the first person to propose that the earth and planets moved around the sun and that the earth would move daily around its own axis.

The noseless astronomer, was said to have died under mysterious circumstances.

These are the laws of planetary motion.]]> 2019-03-29 07:44:58 UTC https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346437891 alexaaaaaaamachdaslichtan https://padlet.com/alexaaaaaaamachdaslichtan/q71xo3qbrldv/wish/346438060 Inventing the universal laws of gravity, Sir Isaac Newton wrote "Philosophiae Naturalis Principia Mathematica" to further understand gravity, the orbits of planets and provide proof that the Earth rotates around the sun. He also invented the world's first reflecting telescope and found outabout the spectrum of light. Addionally, he presented his idea of strength of the force of the gravitational interaction between objects.
