The sun was obviously made of fire, not earth, therefore the sun was lighter than earth (made mostly of earth and water) it was therefore normal that earth, being more massive, would be the central element of the universe, not the flimsy sun. Ptolemy, latin in full claudius ptolemaeus (fl ad 127-145, alexandria), ancient astronomer, geographer, and mathematician who considered the earth the center of the universe (the ptolemaic system. The first speculations about the possibility of the sun being the center of the cosmos and the earth being one of the planets going around it go back to the third century bce copernicus stated that the sun was the center of the universe and that the earth had a galileo's dialogue concerning the two chief world systems of 1632 was a.
The ptolemaic model accounted for the apparent motions of the planets in a very direct way, by assuming that each planet moved on a small sphere or circle, called an epicycle, that moved on a larger sphere or circle, called a deferent. Figure 7 a saddle (negative curvature) shaped universe actually, it looks rather like an infinitely large pringles potato chip in this two-dimensional universe, the curvature is such that triangles have angles that add up to less than 180 degrees and parallel lines diverge (get further apart. There is an abundant wealth of evidence from the workings of physics, chemistry, and properties of the universe, our solar system, and earth which indicate that life on earth did not happen by accident--it was planned these arguments are typically called anthropic principles, where physical.
Two common observations were believed to support the idea that the earth is in the center of the universe: the first observation is that the stars, sun, and planets appear to revolve around the. The roman catholic church dictated that earth, not the sun, was the center of the universe this classical, or ptolemaic, view is represented in an engraving from 1660. That would say we are truly the center of the universe most scientists brushed the observation off as a fluke of some type, and many theories were created to explain it away many awaited the. The idea that the earth was at the centre of the universe with everything revolving around it was one that fitted with religious beleifs afterall, man is the most important of god's creations and so it was proper that the earth should be at the center of a perfect and uniform universe. Galileo believed that the sun was not just the fixed center of the solar system but the fixed center of the universe we now know that the sun is not the center of the universe and that it does move—it simply orbits the center of the galaxy rather than the earth.
Observations to date support the idea that the universe is both isotropic and homogeneous both facts are linked to what is called the cosmological principle the cosmological principle derives from the copernican principle but has no foundation in any particular physical model or theory, ie it can not be `proved' in a mathematical sense. Now you are aware that ‘universe’ is the name given by most astronomers to the sphere whose center is the center of the earth and whose radius is equal to the straight line between the center. Ptolemy's geocentric model was based on the idea that earth is the center of the universe, while copernicus's heliocentric model was developed around the idea that the sun is at the center while these two models were based on opposing ideas, they shared a common belief in uniform circular motion and the use of epicycles. Galileo galilei (italian: the majority of educated people subscribed either to the aristotelian geocentric view that the earth was the center of the universe and that all heavenly bodies revolved around the earth, the inquisition found that the idea of the earth's movement receives the same judgement in philosophy and. In the early 1500s, when virtually everyone believed earth was the center of the universe, polish scientist nicolaus copernicus proposed that the planets instead revolved around the sun although.
For nearly 1,000 years, aristotle’s view of a stationary earth at the center of a revolving universe dominated natural philosophy, the name that scholars of the time used for studies of the physical world. The estimated age of the universe has been increased by the observations of an accelerated expansion of the universe the current best value is 1374 +/- 011 billion years from a fit of 9 years of wmap data to a flat universe, or 13750 +/- 0088 billion years for a fit to wmap+ bao +h 0 data. What evidence supports the idea that a collision between two spiral galaxies might lead to the formation of a single elliptical galaxy definition observations of some elliptical galaxies with stars and gas clouds in their cores that orbit differently from the other stars in the galaxy. While aristotle’s justifications for an earth-centred universe lack scientific support, he offers some compelling observational evidence to justify a spherical earth, the most important being the difference in the position of the polar star as one changes latitude, an observation that offered a way to measure the earth’s circumference.
He believed that the earth was the center of the universe the word for earth in greek is geo, so we call this idea a geocentric theory even starting with this incorrect theory, he was able to combine what he saw of the stars' movements with mathematics, especially geometry, to predict the movements of the planets. The earth was in the center of it all (geocentric), with these planets revolving around it so important did this become in culture that the days of the week were named after the gods, represented. Taking that into account, astronomers have worked out that the galaxies right on the edge of the observable universe, whose light has taken 138 billion years to reach us, must now be 465 billion.
Polish astronomer, mathematician, and canon the observational evidence that the planets moved around the sun while preserving the sacrosanct notion that the earth was the center of the universe copernicus was willing to move one step further away from orthodoxy (1564 – 1642) was the first to provide strong, compelling evidence in. Before the 17 th century, people generally believed that earth was at the center of the universe galileo, however, was not afraid to challenge existing beliefs when he published his work in. The old-earth view of the creation of the universe also assumes that science has proven the true age of the earth and universe in fact, science has only interpreted the evidence from radiometric dating, distant starlight, and the formation of rock layers.
