Who is galileo galilei

Heres a simple answer

Galileo Galilei was an Italian polymath. Galileo is a central figure in the transition from natural philosophy to modern science and in the transformation of the scientific Renaissance into a scientific revolution.

Galileo Galilei is an important forefather to much of what we know today about physics and astronomy. In fact, he was one of the first people to claim that the sun was the center of the universe, not the Earth. He was also the first to use the telescope to examine celestial bodies. Finally, he realized that in a vacuum, if two different weighted objects were dropped, they would land at the same time. Those are just a few of his many accomplishments.
