Geocentric vs. Heliocentric

Front

What is the Geocentric model of the universe?

Back

The Geocentric model is an astronomical theory that places the Earth at the center of the universe, with all other celestial bodies, including the Sun and stars, orbiting around it.

Front

Who is known for formulating the laws of planetary motion?

Back

Johannes Kepler is known for formulating the laws of planetary motion, which describe the orbits of planets around the Sun.

Front

What does the term 'Heliocentric' mean?

Back

Heliocentric refers to a model of the solar system where the Sun is at the center, and the planets, including Earth, orbit around it.

Front

Who proposed the Heliocentric theory?

Back

Nicolaus Copernicus proposed the Heliocentric theory, which suggested that the Sun is at the center of the universe.

Front

What is the significance of Galileo's observations?

Back

Galileo's observations provided strong evidence for the Heliocentric model, including the discovery of Jupiter's moons and the phases of Venus.

Front

What shape did Kepler determine the orbits of planets to be?

Back

Kepler determined that the orbits of planets are elliptical, not circular.

Front

What does 'geo-' in Geocentric refer to?

Back

The prefix 'geo-' means 'Earth'.

Front

What are the main differences between the Geocentric and Heliocentric models?

Back

The Geocentric model places Earth at the center of the universe, while the Heliocentric model places the Sun at the center.

Front

What evidence did Copernicus provide for the Heliocentric model?

Back

Copernicus provided a mathematical model that explained the retrograde motion of planets and simplified the understanding of their movements.

Front

How did the scientific community react to the Heliocentric model initially?

Back

The scientific community was largely resistant to the Heliocentric model initially, as it contradicted the long-held Geocentric view supported by the Church.
