How did Galileo investigate and prove the model of heliocentrism correct? (1 point) He only used mathematical calculations to prove the model of heliocentrism correct. He improved on the sextant and quadrant to determine the movements of planets. He used the telescope to make observations about the solar system. He used biblical teachings to prove the model of heliocentrism correct.

Galileo’s groundbreaking work in favor of heliocentrism was primarily driven by his use of the telescope, an astronomical instrument he famously improved. With this new tool, he observed the moons of Jupiter, the phases of Venus, and the surface of the Moon, providing compelling evidence against the geocentric model that positioned Earth at the center of the universe. These observations vividly illustrated that celestial bodies did not orbit Earth, but rather had their own motion, supporting the heliocentric theory proposed by Copernicus. Beyond just the observations, Galileo faced significant opposition from the Church and scholars of his time, who were staunch advocates of the geocentric view aligned with biblical interpretations. Still, he boldly published his findings, notably in "Dialogue Concerning the Two Chief World Systems," effectively sparking further scientific inquiry. His work laid the groundwork for modern astronomy and showcased the importance of observation and experimentation in scientific inquiry.
