2016年4月30日 · Aristotle contributed a geocentric model for the universe, in 4C BC.with Moon, Mercury, Venus, Sun, Mars, Jupiter and Saturn moving around the Earth, with fixed stars beyond. This model was superseded by Aristarchus' heliocentric model, a century later. It is pertinent to mention that philosopher Aristotle was not a scientist.

2016年3月21日 · In Aristotle world the earth is composed of four elements: Earth, Water, Fire and Air. It is at the center and it does not revolve around anything else or rotate around its own axis. It is surrounded by ten concentric spheres made of a perfectly transparent substance known as "quintessence." These spheres revolve around the earth, carrying the other celestial bodies: 1) …

2016年6月13日 · They thought the Earth was the centre of the Universe and everything revolved around it and that those orbits were circular. Sometimes great thinkers just get it wrong. So let's talk about Aristotle. As he thought about the heavens and creation and divinity, he reasoned: that the Earth was the centre of the universe. Not only was there ample evidence of things going …

2016年2月9日 · Ptolemy included epicycles in his orbits. Ptolomy's model of the solar system was geocentric, where the sun, moon, planets, and stars all orbit the earth in perfectly circular orbits. The problem with perfectly circular orbit around the Earth is that they do not explain the occasional backward motion, or retrograde motion, of the planets. The Greeks insisted that the …

2017年2月1日 · The Copernican view of the universe put the Sun at the center, and this broke from the widely accepted (be even the church at the time) that the Earth was at the center (Geocentric view). Ptolemy (as well as everyone) preached the Geocentric model. Copernicus was excommunicated by the church because his views were TOTALLY different than theirs.

2016年3月22日 · Before Copernicus most people were thinking that the Earth is at center of universe. In 1609 Galileo observed sky through his home made telescope. He found 4 moons orbiting Jupiter..It was a proof that bodies are orbiting other planets Not earth alone. He found the crescent shape of Venus through his telescope.This could happen only if Sun is at center,. …

2018年3月20日 · Copernicus's beliefs contradicted Church tradition and doctrine The Catholic church had placed Church traditions and the teaches of the Catholic church on a equal if not superior position to scripture. Copernicus's beliefs contradicted the Churches teachings about the nature of the universe. St Thomas Aquanus had written a systematic theology based on the …

2017年5月19日 · From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid. Let's describe them from smallest to largest. In fact the size order is not exact as there are exceptions. An asteroid is a rocky body which lies in the asteroid belt between Mars and Jupiter. They are typically quite small object. The largest asteroid Ceres has been …

2016年8月15日 · The currently held view is that the Big Bang resulted in an inflationary Universe as opposed to the static model suggested by the Steady State theory. The Big Bang means that the Universe evolved from a singularity and the Universe is inflationary, it being finite and unbounded, Einstein had originally postulated the need for a cosmological constant as the …

2018年1月13日 · Well, Bohr's model of the atom assumes fixed orbits AND trajectories for the electron. Simultaneously known orbits and trajectories violate the Heisenberg Uncertainty Principle. Bohr's model of the nitrogen atom is: The problem is, electrons do NOT travel in fixed orbits, and they do NOT travel with fixed trajectories. That is, they should NOT have …
