What proof can be provided that the world is not the center of the universe.?

Question

What proof could acient astronomers have been provided with to proove that the earth was not the center of the universe.

Answer 1

Does not look like it can be proved or disproved.

But if you mean by center, everything revolves around the world, then we know the answer.

Earth revolves around the sun. Plenty of proofs exist for this.

The sun is not at the center of our milky way galaxy, nor do all stars of our galaxy revolve around our sun. Again we have proof for this.

Do all other galaxies revolve around our milky way galaxy ? No, we are just a small part in some corner of our local cluster of galaxies. And there are many such clusters.

But, from a geometric point of view, is the world at the center of the universe, assuming the universe to be sperical ? Though highly unlikely, I do not think this can be proved or disproved.

Answer 2

The proof is by negation. The math points to the universe having NO center. Therefore, nothing, including the earth, can be at "the center".

For the ancients, any observation that might suggest that the earth was not the center of the universe was often dealt with by fudging some fancy Euclidian spherical geometry, giving rise to such intricate and complicated geo-centric models as the Ptolemaic system. Although we often look at Aristotle and Ptolemy as being somewhat ignorant for their views, these actually represent a seroius and sophisticated effort to account for the all the data is a neat and coherent manner.

Further they were using the best means of observation, measurement, and math available in their day for this synthesis. It was not until the use of the telescope and the advent of the rudiments of calculus and differential equations that more sophisticated models better accounted for the data. (Keep in mind that even Copernicus' sun-centered planetary system was only a theory until Galileo directly observed the phases of Venus through his glass.)

Answer 3

I'm not sure that there's any obvious proof. The idea of a heliocentric solar system wasn't widely accepted until data continued to support Kepler's laws, and they were based on analysing a lot of observational data. You can work backwards through the development of better instruments and observing techniques, but I don't think there's anything that can be singled out as THE proof.

The planets were a problem for geocentric theories, but epicycles were viewed as an acceptable solution.

Answer 4

Who cares. I think the fact that ancient astronomers KNEW the world was not the center of the universe well before xians arrived and redefined everything wrong. PI does not equal 3 xians.

Answer 5

Actually, there were many ancient astronomers who did in fact reach this conclusion based on careful observations of the heavenly bodies including the sun, moon and planets.

Answer 6

the fact that thew earth revolves around a center point, "The Sun" in absolute proof that the world can't be the center

Answer 7

it actually is the center of the universerse, if you establish it a point of reference. according to Einsteins general theory of relativity, everything depends on your point of reference. is the earth traveling through the universe or is the universe traveling around the earth. it all has to do with trying to establish absolute motion.

Answer 8

The planets in the sky, or "wandering stars", don't go along with all of the other stars in the sky, and prove that they rotate around something other than the earth

Answer 9

Human could not undrestana how much the univers is huge so,nobody knowes center of it.

Answer 10

Gravity? Theory of relativity? Telescopes? Not really sure what you are asking...
