Galileo Galilei – The Experimentalist Did experiments (falling bodies) rather than studying Aristotle Major Works Siderius Nuntius (1610) Dialogue concerning.

Astronomy is remote sensing We cannot repeat (or change) the Universe in a controlled environment. We cannot make planets, stars, or galaxies. We cannot.
