How did Galileo prove ptolemy's theory of space wrong?

Answer 1

Copernicus produced his model with the Sun at the centre in 1543, and then in 1609 Kepler produced the model that we use now. Kepler's model also uses the idea of having the Sun at the centre. No-one proved anything but after Newton's discoveries in physics it was realised that Kepler's model fitted exactly with Newton's later theories in gravity and dynamics, so that's why it became accepted, and it still is.

Answer 2

Galileo made the first astronomical discoveries with a telescope, and one important thing he discovered was the phases of Venus.

Venus has a crescent phase when it is close to us, and a gibbous phase when it is far away on the other side of the Sun (as we now know). But in the Ptolemaic system, Venus never goes behind the Sun.

Therefore Galileo's discovery raised a few doubts about the Ptolemaic system but it took time before other discoveries were made that brought about big changes to our model of the solar system, and these happened long after Galileo's time.

One of the major discoveries was Kepler's laws of motion, which Galileo did not accept because he preferred the older Copernicam system. Later, Kepler's theory was shown to be correct by Newton's discoveries.

Answer 3

because he did not realise earth is not the center of our solar system

Answer 4

It was Copernicus who discovered the heliocentric system, but it was Galileo who proved it with his telescope

Answer 5

it was Copernicus who figured it out but Galileo was the one who proved it

Answer 6

Galileo
