What evidence did Galileo have to his theory?
Galileo's theory was supported by evidence from his observations using a telescope, which showed that the Earth orbits the Sun and not the other way around as commonly believed at the time. He also provided evidence of the phases of Venus, the moons of Jupiter, and the mountains on the Moon, all of which supported his heliocentric model of the solar system.
A theory is supported by?
evidence, experimentation, and observational data that consistently confirm its predictions and conclusions.
What did ptolemy and Copernicus and Galileo found out about the solar system?
Ptolemy proposed a geocentric model, with Earth at the center and planets orbiting it. Copernicus suggested a heliocentric model, with the Sun at the center of the solar system. Galileo's telescopic observations supported the heliocentric model and provided evidence for Copernicus' theory.
Does a theory have to be supported by evidence?
Yes, a theory should be supported by evidence in order to be considered valid and credible. Evidence helps to substantiate the claims and predictions made by a theory, allowing for testing, verification, and refinement of the theory as needed.
What instrument did Galileo develop which help find evidence to support the heliocentric theory?
Galileo developed the telescope, which allowed him to observe celestial bodies such as the moons of Jupiter and the phases of Venus. These observations provided evidence to support the heliocentric theory proposed by Copernicus.
