Question

1. how did galileo and his fellow astronomers change the worldview of how people viewed the universe? (1 mark)

Explanation:

Galileo and fellow astronomers (like Copernicus - supported by Galileo's observations) promoted the heliocentric model, where the Sun, not Earth, is at the center of the solar system. This contradicted the geocentric (Earth - centered) view, using telescopic observations (e.g., moons of Jupiter, phases of Venus) to show celestial bodies move independently of Earth, shifting the worldview from a geocentric, static universe (with Earth as the center and all celestial bodies orbiting it) to a heliocentric, more dynamic one, and laid groundwork for modern astronomy.

Answer:

Galileo and fellow astronomers (supporting heliocentrism) changed the worldview by promoting the heliocentric model (Sun - centered solar system, via telescopic observations like Jupiter’s moons, Venus’ phases) to replace the geocentric (Earth - centered) view, showing celestial bodies move independently of Earth and shifting toward a dynamic, Sun - centered cosmic understanding.
