The geocentric model says that the earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it. The early heliocentric models consider the sun as the center, and the planets revolve around the sun.
Q. Why was geocentric model accepted?
It was embraced by both Aristotle and Ptolemy, and most Greek philosophers assumed that the Sun, Moon, stars, and visible planets circle the Earth. Christianity taught that God placed the earth in the center of the universe and this made earth a special place to watch human life unfold.

Q. Is the heliocentric theory used today?
Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Still in use today, the mathematical equations provided accurate predictions of the planets’ movement under Copernican theory.
Q. What do heliocentric and geocentric have in common?
Both were created by a Greek astronomer. Both are ways to display the Universe. The models both contain 3 main objects: Earth, Sun, and other planets. Planets orbit in some way.
Q. Who created the heliocentric model?
Nicolaus Copernicus
Q. Why is the heliocentric model important?
It discredited many people’s theories and modern belief at the time. The heliocentric theory is important today, because it led to the advancement and accuracy in astronomical tools, both physical and mathematical and changed the way scientists understand the design of our solar system.
Q. Why was the geocentric model replaced by the heliocentric model?
The geocentric model was eventually replaced by the heliocentric model. Copernican heliocentrism could remove Ptolemy’s epicycles because the retrograde motion could be seen to be the result of the combination of Earth and planet movement and speeds. The Ptolemaic order of spheres from Earth outward is: Moon.
Q. Why doesn’t the universe have a center?
Although planets and stars do represent non-uniformities in the spacetime structure, on the universal scale, such uniformities are randomly dispersed. On average, therefore, the universe is uniform. Being infinite and uniform, there is no way to define a center of mass for the universe.
Q. Is also called the crust?
Earth’s Crust. “Crust” describes the outermost shell of a terrestrial planet. Earth’s layers constantly interact with each other, and the crust and upper portion of the mantle are part of a single geologic unit called the lithosphere.
Q. Which is the coldest layer of atmosphere?
mesosphere
Q. Is mantle the thickest layer of earth?
The mantle At close to 3,000 kilometers (1,865 miles) thick, this is Earth’s thickest layer. It starts a mere 30 kilometers (18.6 miles) beneath the surface. Made mostly of iron, magnesium and silicon, it is dense, hot and semi-solid (think caramel candy). Like the layer below it, this one also circulates.
