the theory of how to make a telescope
Galileo Galilei changed the world today because he invented many space telescopes that still come in handy today, he also was the one of the only people that experimented his own theories. I LOVE RYAN ANDREW SWIFT
Galileo Galilei published several influential works, including "Sidereus Nuncius" ("Starry Messenger"), in which he described his observations using a telescope; "Dialogue Concerning the Two Chief World Systems," which compared the Copernican and Ptolemaic systems; and "Dialogues Concerning Two New Sciences," which laid the groundwork for the science of dynamics and the study of materials.
He didn't invent science.
Galileo's other interest were art and medicine.
Galileo performed experiments to test his ideas.
