In a time period where the Church reins supreme, anything that goes against the teachings or beliefs would be considered heresy and consequences would be death. Galileo was a man of science with logical reasoning and evidences but this conflicted with religion. As long as he carries science with him, trouble would follow behind him. Throughout the play science and religion cannot co-exist.
Galileo was fascinated with the instrument that enables to enlarge, zooms objects. With the instrument he used it for astronomic research. He had shown the instrument to Prince Cosimo De' Medici but with little knowledge to comprehend what they were seeing, they were in disbelief. The cardinals, monks, scholars were also in disbelief and mocking Galileo research. "Don't hurl us off onto the moon. There are nasty sharp mountain peaks on the moon, brethren!" (pg72) quoted by second monk. They do not accept the fact of the moon being similar to "motherly earth" because earth is the only unique planet with life that "God granted". Andrea quoted these type of people lived in a cage. "He's in there with his eye glued to that diabolical instrument." Quote by the infuriated monk. This shows that science is perceived as negative and evil.
The relationship between science and religion is complex. Some who just learned about science are confused and it conflicts on their religion. "you've destroyed my faith in a lot of things, Mr. Galilei" (pg 61) quoted by Curator. It was difficult for people to accept these scientific studies because religion revolved around their daily life. People were born and raised to believe. Religion is viewed to be far superior to science. People had gone through cruel and unusual punishment when they state God was nowhere to be found. "Ten years ago a man was burned at the stake for saying that." (pg 63) quoted by Sagredo. Galileo argued that the eyes cannot fool what they see; it's harder to deny when something actually is occurring....
