How can planet retrograde motion be explained by the Earth-center hypothesis By the Sun-center hypothesis?

In the Geocentric Hypothesis (Earth-centered), retrograde motion can only be explained by describing the motion of planets as complex, curlicue paths. In the Heliocentric Hypothesis (Sun-centered), retrograde motion is described as changes in relative motion as the Earth overtakes a slower-moving planet in an outer orbit, or is overtaken by a faster-moving planet in an inner orbit. In the Heliocentric Hypothesis, all planets move in more-or-less circular orbits at more-or-less constant speeds, but planets closer to the Sun move faster. Thus, the Earth can overtake and pass each of the outer planets, making them appear to move "backward" (retrograde) for a time.

What did Artemis explain in nature?
She really didn't explain things in nature. She explained the human endeavor of hunting. She was the goddess of animals so you could say she explained animals. She and her twin brother Apollo spread plagues through cities so you could also say they explained that.

What are the contributions of Eudoxus in geocentric theory?
He created a model for the universe that explained retrograde motion if Earth was at the centre.
How can a experiment support or fail to support a hypothesis?
a hypothesis is given to explain a phenomena which has not been explained till then. it can be supported by an experiment if that experiment gets the other results regarding that particular phenomena in agreement with that being predicted by the hypothesis and if any contradictory fact arises or the result doesnt match the prediction then the hypothesis is again thought upon or totally discarded at times
What are the main qualities of a good hypothesis?
iA hypothesis is a proposed explanation for an observable phenomenon. For a hypothesis to be put forward as a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous obserations that cannot satisfactorily be explained with the available scientific theories.These are the essential traits of a good hypothesis:TestibilitySimplicityScope - the apparent application of the hypothesis to multiple cases of phenomenaFruitfulness - the prospect that a hypothesis may explain further phenomena in the futureConservatism - the degree of "fit" with existing recognized knowledge-systemsA hypothesis cannot contradict scientific laws.
How did nicolous copernocus and galilio find out that the earth moves around the sun?
it was very difficult to understand the retrograde motion of other planets if earth was considered to be at the center of the solar system but it could be easily explained if earth is considered to revolve around the sun along wit other planets. So explanation of retrograde motion of other planets made them realize that earth moves around the sun.
Why was it difficult for ancient astronomers to explain about the apparent retrograde motion?
If, as ancient astronomers thought, that our Earth was the center point of rotation for other planets, then it is difficult to explain why those planets would move in a direction opposite to their rotation. Ptolemy came up with a solution that worked, but it was a cumbersome one. Nicolae Copernicus was able to show that this retrograde motion could be explained easily if it were assumed that our Sun was the actual center of rotation of the planets.
What geometric arrangements did ptolemy use to explain retrograde motion?
Earths faster motion makes Mars appear to be going backwards, the backwards motion, in fact, is what caused retrograde motion. --Ptloemy used Epicycles to explain how geocentrical models worked.
How do you identify a hypothesis?
A hypothesis (from Greek ὑπόθεσις; plural hypotheses) is a proposed explanation for an observable phenomenon. The term derives from the Greek, ὑποτιθέναι - hypotithenai meaning "to put under" or "to suppose." For a hypothesis to be put forward as a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. I did not know the exact meaning myself, so I copied this from wikipedia.

What is needed for a good hypothesis?
For a basic hypothesis, try an "If, then, because statement".For example: Say I'm doing a hypothesis about rainy weather.If I wear a rain jacket while it is raining then I will stay dry because the materials in the jacket will wick the water, preventing it from touching my skin and thus getting me wet.Hypotheses are generally short sentences which are further explained throughout a research paper/lab report.
Why Does mr wormley have a girlfriend?
This question is quite simple. it can be explained through the scientific process. My hypothesis is that he really does not have a girlfriend but rather has psychological problems based on self esteem. therefore i believe that theoretically he does not have an actual girlfriend.
How was Ptolemy's idea of retrograde different from Copernicus' idea of retrograde motion?
We now understand that all the planets travel round the Sun, and a planet's retrograde motion happens as the Earth overtakes the other planet in its orbit. That was also Copernicus's view although we now use Kepler's theory, but on this point the two models are in agreement. In Ptolemy's model the Earth is stationary in the centre, and the planets move on circles and epicycles, explained as follows. Using Mars as an example and assuming the orbits of Earth and Mars are circular for simplicity, the Earth is at the centre and there is then a circle (or deferent) round it with a radius of 1.524 units. The epicycle is a smaller circle whose centre travels round the deferent in 687 days. The epicycle has a radius of 1.000 units and Mars travels round this in 365¼ days. That was Ptolemy's geometric construction to explain the motion of Mars, and the retrograde motion happens when Mars on its epicycle moves close to the Earth.
What is that which cannot be explained by scientific method?
If I had to say something it would be anything that cannot be tested. Existence of god, ghosts, etc. as the basis of the scientific method is to prove a hypothesis through tests and observations. Kinda butchered the explanation but you get what I mean. (I hope.)
