Two of them are the geocentric theory and the heliocentric theory.]]> 2017-10-01 17:14:03 UTC https://padlet.com/nuhii064/lwv5djr1u8do/wish/192784517 nuhii064 https://padlet.com/nuhii064/lwv5djr1u8do/wish/192784640 The geocentric theory said that the earth was in the middle of the universe and that the celestial bodies orbits around the earth.
this theory was depeloved in ancient greece by a group of philosophers and that tries to explain how the stars,the planets and other celestial bodies orbits the earth.The philosophers believed that each planet orbits around a circle called epicycle and that all was orbiting around  the earth.]]> 2017-10-01 17:15:04 UTC https://padlet.com/nuhii064/lwv5djr1u8do/wish/192784640 nuhii064 https://padlet.com/nuhii064/lwv5djr1u8do/wish/192784723 The geocentric theory is completely different. This theory tries to explain that the Sun was in the middle of the universe and the planets (including the earth) orbits the sun. That wants to show that the celestial bodies revolve around the sun. This theory was determinated because the sun was bigger than the earth so they proposed that it was the earth who orbits the sun.]]> 2017-10-01 17:15:43 UTC https://padlet.com/nuhii064/lwv5djr1u8do/wish/192784723 nuhii064 https://padlet.com/nuhii064/lwv5djr1u8do/wish/192786193 In that picture we can see that the earth is in the middle of the galaxy and the sun and the other planets orbits around. This is the geocentric theory.]]> 2017-10-01 17:29:02 UTC https://padlet.com/nuhii064/lwv5djr1u8do/wish/192786193 nuhii064 https://padlet.com/nuhii064/lwv5djr1u8do/wish/192786659 here we can see that the sun is in the middle of the universe  and the earth is orbiting around it. this is the heliocentric theory]]> 2017-10-01 17:33:38 UTC https://padlet.com/nuhii064/lwv5djr1u8do/wish/192786659
