He made a big difference by challenging old accepted theories and making important discoveries in astronomy and dynamics.
Maybe his most important discovery was the moons of Jupiter, the first time any objects had been seen that definitely did not orbit the Earth. This encouraged Galileo to take up the Copernican heliocentric theory which has the Sun at the centre of the local system of planets known as the Solar System.
Science did not fully demonstrate the accuracy of the heliocentric theory until the 19th century but Galileo's important contribution was to stimulate the debate.
His disagreement with the catholic church was taken up by protestant propagandists, which did nothing for the quality of the scientific debate, but gradually the heliocentric theory became universally accepted by the first half of the 19th century.
