Galileo used the telescope he built to observe the heavens and examine the surface of the moon.   At that time, they thought that force was not necessary for the body to continue moving, but an experiment showed that this was not the case, and later it led to Newton's first law. 
What do you think about his invention?

Galileo, while not the telescope’s inventor, pioneered its use by turning it toward the night sky. His observations birthed modern astronomy, deepening our understanding of the universe and its workings. 🌠🔭🌌
