Question 2 (1 point)
Nicolaus Copernicus developed the theory of a heliocentric solar system in the 1500s. With the invention of the telescope more than 100 years later, Galileo Galilei was able to provide scientific evidence to support this theory. What kind of scientific evidence did Galileo provide for Copernicus's theory?
a
educated predictions
b
exact measurements
c
reliable observations
d
modern photographs
c
Reliable observations
e
Hilarious sketches of planets doing yoga. Just kidding! The correct answer is c) reliable observations. Galileo used his trusty telescope to observe the heavens and gather evidence that supported Copernicus's heliocentric theory. He discovered things like the phases of Venus and the moons of Jupiter, which showed that not everything revolves around the Earth. Galileo sure knew how to rock the telescope!
The scientific evidence that Galileo Galilei provided for Copernicus's theory of a heliocentric solar system was reliable observations (c). Galileo used his telescope to observe the moons orbiting Jupiter, the phases of Venus, and the irregularities on the surface of the Moon. These observations supported the idea that celestial bodies were not orbiting the Earth, but instead were moving around the Sun.
To determine what kind of scientific evidence Galileo Galilei provided for Copernicus's theory of a heliocentric solar system, we can examine the options given and analyze each one.
a) Educated predictions: Educated predictions are based on knowledge and reasoning, but they do not provide concrete evidence. This option can be eliminated.
b) Exact measurements: Exact measurements involve precise and accurate quantification, but in this case, Galileo did not have the kind of advanced instruments necessary to measure the distances accurately. Therefore, this option can also be eliminated.
c) Reliable observations: Galileo made significant advancements in astronomical observations using his telescope. He discovered that Venus goes through phases similar to the Moon, observed the four largest moons of Jupiter orbiting around it, and noticed that the Moon's surface had craters and mountains. These observations provided scientific evidence that supported Copernicus's theory. Therefore, this option is the correct answer.
d) Modern photographs: Galileo lived in the 16th and 17th centuries, long before the invention of photography. So, he did not have access to modern photographs. This option can also be eliminated.
In conclusion, Galileo Galilei provided reliable observations as scientific evidence to support Copernicus's theory of a heliocentric solar system.
