Question

Which events took place during the Copernican revolution, when most people started to believe in a heliocentric model of the solar system? Check all that apply.
Aristotle developed his model of the solar system.

Copernicus rediscovered Aristarchus’s heliocentric model.

Hawking proposed theories that increased curiosity about space.

Scientists checked, confirmed, refined, and mathematically proved ideas.

Newton’s theories of gravity increased understanding of the movement of planets.

Answer 1

2) Copernicus rediscovered Aristarchus’s heliocentric model.

Before Copernican Revolution, people did believe in the ptolemain model that establishes the description of the Universe with the earth at the center having sun, moon, starts and planets all orbited earth. On the other hand, the heliocentric model establishes the sun at the center of the solar system and this starts with the publication of Nicolas Copernicus named De revolutionibus orbium coelestium.

5) Newton’s theories of gravity increased understanding of the movement of planets.

The revolution ended with Isaac Newton's work over a century later. As you well know, Newton was both a physicist and mathematician, better known for his prodigal work called Philosophiæ Naturalis Principia Mathematica. In this revolution, he is known for his laws of motion and universal gravitation increasing understanding of the movement of planets.

Answer 2

Answer:

The correct option is B. Copernicus rediscovered Aristarchus’s heliocentric model.

Explanation:

Before the Copernican revolution, people believed that the Earth was present in the centre of the universe and it was stationary. This theory was then amended by Nicolaus Copernicus at the time of the Copernican revolution. He made models which showed the Sun to be the centre of the universe instead of the earth and other heavenly bodies to be rotating around the Sun. This model is known as the heliocentric model.
