It fails to describe the basic motions of the planets without a number of "arbitrary" actors. It fails to describe the now-observed motions of the host of stars around us.

What is the centre in the Ptolemaic model of the universe?
Earth
How did galileos findings with the telescope disprove the Ptolemaic theory?
A model is never technically disproven or proven. The ptolemaic model is no longer accepted because it does not adequately explain observations. The heliocentric model was accepted gradually because it was a better explanation for observed phenomena. However, people continued to believe the ptolemaic model long after it was irrational to do so.
What is the majority of the energy in our universe?
Something called "dark energy" which provides almost 70% of the total energy in the observable universe and is causing the expansion of the universe to accelerate (instead of decelerate as expected in the basic big bang model of the universe).
How was Copernicus' model of the universe different from ptomely's model?
Ptomely thought that the earth was at the centre of the universe and everything revolved around it. His model had everything moving in perfect circles or circles within circles. Copernicus suggested that the Earth in fact revolved around the sun. It wasn't until Galileo and the invention of the telescope that Copernicus was proved right Later Kepler went on to prove that the planets orbit in elliptical and not circular orbits.
What is flaws in a chemistry model?
The meaning of flaw in this context is a defect in the theoretic model.
In the Ptolemaic Greek model of the universe the stars are attached to the?
The stars in the Ptolemaic model of the universe move on or are attached to a celestial sphere.
What is the centre in the Ptolemaic model of the universe?
Earth
What the ptolemaic of the universe had in the center of the universe?
This model of the universe placed the Earth at the center of the universe
In the Ptolemaic (Greek) model of the universe the stars are attached to the?
celestial sphere . . . ?
What are the geocentric and heliocentric theories of the universe?
The Geocentric or Ptolemaic Model put the earth at the center of the Universe. The Heliocentric Model postulated by Copernicus and, before him, Aristarchus, places the Sun at the center of the Solar System. Galileo's observations proved the validity of the Heliocentric Model.
What was the main idea in the ptolemaic system?
The main idea in the Ptolemaic system was that the Earth was at the center of the universe, with the Moon, Sun, planets, and stars orbiting around it in perfect circles. This geocentric model dominated Western astronomy until it was eventually replaced by the heliocentric model proposed by Copernicus.
When Copernicus first created his Sun centered model of the universe it did not lead to substantially better predictions of planetary positions than the Ptolemaic model?
Copernicus used perfect circles for the orbits of the planets.
Why do scientists not accept the ptolemaic model?
The Ptolemaic model is also known as the geocentric model, where the Earth is at the center of the solar system. Scientists refute this because orbital paths show that the solar system is heliocentric.
Why is heliocentric and geocentric a theory?
A geocentric theory is one that states the universe is centered by Earth. Geo means earth. The old Ptolemaic Model of the universe has earth as the center. A heliocentric theory is one that is centered by a source of heat. Helio = heat. It basically states that the sun is the center of our galaxy. (Copernican Model)
What was the old Ptolemaic conception of the universe?
The Earth was the center of the universe and the "heavenly bodies", such as the moon, sun, planets and stars, rotated in their own spheres around the Earth in a pattern. The order of spheres from Earth outward are:MoonMercuryVenusMarsJupiterSaturnFixed starsSphere of Prime Mover
Does this expanding universe model mean that the milky way galaxy is the center of the universe?
No it does not. It is my basic understanding of this theory that the 'true center' of the universe would be mostly devoid of material.
