By August that year, Galileo had built an 8 power telescope while just two or three months later, he had built another with a magnification two and a half times greater. In January 1610 he discovered four moons revolving around Jupiter. Telescopes of 2x magnification had been in existence for only a couple of years and the polymath from Pisa had now built himself one 10 times as powerful. Galileo's work laid the foundation for today's modern space probes and telescopes.

The notion that the moon had a topology like the Earth led to speculation on what life might be like on the Moon. Similarly, the other two options are also famous discoveries of Galileo. But more importantly he also spurred on other astronomers to apply the laws and lessons of mathematics and logic to their observations in a quest to understand how the universe works. It can be seen at certain time without the aid of instruments. Which of the statements below is true? Saturn was not a single planet, but rather a triple planet!

Remembering Galileo and the first astronomers, he did not hesitate to build the telescopes that I couldn't buy. During this period he designed a new form of hydrostatic balance for weighing small quantities and wrote a short treatise, La bilancetta (The Little Balance), that circulated in manuscript form. Johannes Kepler wrote a letter of support the following month while additional observations by other astronomers confirmed Galileos claims. Indeed, he transformed the way in which people perceived the world and had a life and career that some may not be so familiar with.

Gravity between two objects is __________ proportional to the product of their masses and __________ proportional to the square of the distance between them. Prior to Galileo's conflict with the Church, the majority of educated people in the Christian world subscribed either to the Aristotelian geocentric view that the earth was the center of the universe and that all heavenly bodies revolved around the Earth, or the Tychonic system that blended geocentrism with heliocentrism.
