Galileo Galilei

Galileo Galilei Galileo Galilei was a Roman Catholic and a scientist during the 16th and 17th centuries. He was prisoned because he went against the Church and their religion. The Church believed the geocentric model to be true. The geocentric model, theorized by Aristotle, had the Earth as the center of the planetary system, with the sun going around the Earth. Galileo believed the heliocentric model to be the true model. The heliocentric model, theorized by Copernicus, had the sun in the center of the system, with the planets going around the sun. Galileo taught himself how to grind lenses. He invented the telescope and improved it further on. With his improved telescope, he could see ships in the sea two hours away. His telescopes were then supplied to the navy. Galileo then turned his telescope towards celestial objects. He observed the moon’s surface and saw that it was not as smooth as the naked eye saw it to be. The surface of the moon was actually uneven, rough, and full of cavities. He looked at Jupiter through his telescope and saw 3 stars aligned with the planet. The next night when he looked at them again, their positions had changed. He had discovered the moons of Jupiter. The scientist studied the heliocentric model and the planets movements for months. He saw that Venus had phases like the moon, so he thought it must go around the sun. The Church thought it was ridiculous and banned Copernicus’s idea. If anyone defended that idea, they were accused of heresy. Galileo published a dialogue that contained Copernicus’s ideas, and he was summoned to the Inquisition. The dialogue was banned and put in the Index of prohibited books, and Galileo was put under house arrest. Galileo had also looked back at his works about the physics of motion. Galileo had three illegitimate children, the oldest being Virginia, later renamed Maria Celeste. Maria Celeste was not allowed to be married since she was illegitimate,
